在鋼帶等金屬的軋延製程中，會使用軋延液，其中軋延液中包含軋延油與水，以在軋延製程中幫助潤滑與降溫。由於軋延時，軋輥與鋼帶表面於咬入區域會發生接觸與研磨，因而會產生大量的磨耗鐵粉。這些鐵粉不僅會黏附在鋼帶上，也會摻附在循環的軋延液中。 In the rolling process of a metal such as a steel strip, a rolling solution is used, wherein the rolling liquid contains rolling oil and water to assist lubrication and cooling in the rolling process. Due to the rolling delay, the surface of the roll and the steel strip will contact and grind in the biting area, and a large amount of abrasive iron powder is generated. These iron powders not only adhere to the steel strip, but also adhere to the circulating rolling solution.
冷軋廠之軋延設備的過濾系統包括濾紙過濾系統與磁分離器，為冷軋與清洗製程的主要裝置。濾紙過濾系統與磁分離器可過濾軋延液中的雜質與鐵粉，因此濾紙過濾系統與磁分離器之效能對軋延時之軋延液的品質性能與軋延後之鋼板的表面清淨度具有關鍵的影響。 The filtration system of the rolling mill's rolling equipment includes a filter paper filtration system and a magnetic separator, which are the main devices for the cold rolling and cleaning process.

有鑑於習知軋延設備之操作方式會造成軋延液的油耗偏高以及濾過之含鐵油泥量超高，而造成下游處理的負荷量與成本大增，因此本發明在此提出一種軋延液之監控系統與監控方法，其可提高鐵粉屑與軋延油的分離效率，如此一來不僅可提升軋延液中之軋延油的利用效率，更可大幅減少油泥渣直接排到下游之廢油水處理系統的量。故，應用本發明之軋延液之監控系統與監控方法，可大幅降低軋延液中之油耗，並可有效降低廢油水的處理量，除了可減少廢油水的處理負荷外，亦可降低軋延製程的成本。 In view of the fact that the operation mode of the rolling device causes the oil consumption of the rolling liquid to be high and the amount of the filtered iron sludge to be extremely high, and the load and cost of the downstream processing are greatly increased, the present invention proposes a rolling delay. The liquid monitoring system and the monitoring method can improve the separation efficiency of the iron powder and the rolling oil, so that the utilization efficiency of the rolling oil in the rolling liquid can be improved, and the sludge slag can be directly discharged to the downstream. The amount of waste oil water treatment system. Therefore, the monitoring system and the monitoring method of the rolling solution of the invention can greatly reduce the fuel consumption in the rolling liquid, and can effectively reduce the processing amount of the waste oil water, in addition to reducing the processing load of the waste oil water, the rolling can also be reduced. The cost of the process.
請參照圖1，其係繪示依照本發明之一實施方式的一種軋延液之監控系統與軋延設備之裝置示意圖。軋延液之監控系統100適用以監測與控制軋延設備200中之軋延液的使用，藉以降低軋延液的油耗，而提升軋延液的使用效率，並大幅減少廢油水的處理量。軋延液一般包含軋延油與水、磨耗金屬粉，在金屬加工的軋延製程中，可幫助潤滑減摩與冷卻降溫。 Please refer to FIG. 1 , which is a schematic diagram of a device for monitoring and rolling equipment of a rolling solution according to an embodiment of the present invention. The rolling liquid monitoring system 100 is suitable for monitoring and controlling the use of the rolling liquid in the rolling equipment 200, thereby reducing the fuel consumption of the rolling liquid, improving the use efficiency of the rolling liquid, and greatly reducing the processing amount of the waste oil. The rolling solution generally includes rolling oil and water, and wear metal powder, which can help to reduce friction and cool down during the rolling process of metal processing.
在一些例子中，軋延設備200主要包含軋機202、髒液回收槽204、過濾系統206以及軋延液槽208，其中軋機202、髒液回收槽204、過濾系統206以及軋延液槽208依序設置，而軋延液主要也是以此順序在軋延設備200中循環。舉例而言，髒液回收槽204位於軋機202之下游，以接收軋延期間從軋機202傳送來之使用過的軋延液；過濾系統206位於髒液回收槽204之下游，以過濾從髒液回收槽204傳送來之軋延液；軋延液槽208位於過濾系統206之下游，以接收經過濾系統206過濾後之軋延液，來回收使用；軋機202位於軋延液槽208之下游，以接收並利用添加補充水與軋延油後之經過濾之軋延液，來進行金屬胚的軋延。在軋延液槽208中，可對軋延液加熱，使軋延液之溫度保持恆溫，例如約50℃至55℃。此外，經過濾而回收循環到軋延液槽208之軋延液的量通常會減少，因此可在軋延液槽208中添加軋延油與補充水。 In some examples, the rolling apparatus 200 mainly includes a rolling mill 202, a dirty liquid recovery tank 204, a filtration system 206, and a rolling liquid tank 208, wherein the rolling mill 202, the dirty liquid recovery tank 204, the filtration system 206, and the rolling liquid tank 208 are The setting is performed, and the rolling solution is mainly circulated in the rolling apparatus 200 in this order. For example, the effluent recovery tank 204 is located downstream of the mill 202 to receive the used temperate from the mill 202 during the rolling; the filtration system 206 is located downstream of the effluent recovery tank 204 to filter the effluent The rolling solution is sent from the recovery tank 204; the rolling solution tank 208 is located downstream of the filtration system 206 to receive the rolling liquid filtered by the filtration system 206 for recycling; the rolling mill 202 is located downstream of the rolling liquid tank 208. The rolling of the metal embryo is carried out by receiving and using the filtered rolling solution after adding the make-up water and the rolling oil. In the rolling solution tank 208, the rolling solution may be heated to maintain the temperature of the rolling solution at a constant temperature, for example, about 50 ° C to 55 ° C. Further, the amount of the rolling solution which is recovered by filtration and recycled to the casting bath 208 is usually reduced, so that rolling oil and make-up water can be added to the rolling solution tank 208.
在一些例子中，軋延液之監控系統100主要包含數據處理與控制系統102、線上皂化價檢測裝置104、排 放開關106以及高壓水噴射裝置108。數據處理與控制系統102可例如設於軋機202之控制室中。在一些示範例子中，數據處理與控制系統102可預先儲存有油皂化價與油劣化率之關係表，以利對皂化價進行比對判斷。 In some examples, the rolling fluid monitoring system 100 mainly includes a data processing and control system 102, an online saponification price detecting device 104, and a row. The switch 106 and the high pressure water jet device 108 are placed. Data processing and control system 102 can be provided, for example, in the control room of rolling mill 202. In some exemplary examples, the data processing and control system 102 may pre-store a table of oil saponification prices and oil degradation rates to facilitate comparison of saponification prices.
線上皂化價檢測裝置104和數據處理與控制系統102訊號連接。舉例而言，線上皂化價檢測裝置104利用電性連接的方式來和數據處理與控制系統102訊號連接。當然，線上皂化價檢測裝置104亦可以藍牙等無線傳輸方式來和數據處理與控制系統102訊號連接。線上皂化價檢測裝置104同時也與軋延液槽208連接。線上皂化價檢測裝置104配置以檢測軋延液槽208內之軋延液的皂化價，並將檢測到之軋延液的皂化價的資訊透過訊號傳送的方式傳遞給數據處理與控制系統102。 The online saponification rate detecting device 104 is coupled to the data processing and control system 102. For example, the online saponification rate detecting device 104 is electrically connected to the data processing and control system 102 by means of electrical connection. Of course, the online saponification price detecting device 104 can also be connected to the data processing and control system 102 by a wireless transmission method such as Bluetooth. The online saponification rate detecting device 104 is also connected to the rolling solution tank 208 at the same time. The online saponification price detecting device 104 is configured to detect the saponification price of the rolling solution in the rolling solution tank 208, and transmit the information of the detected saponification price of the rolling solution to the data processing and control system 102 by means of signal transmission.
由於皂化價的高低可用以判斷油的劣化程度，因此利用線上皂化價檢測裝置104來檢測軋延液槽208內之軋延液的皂化價，可先判斷軋延液槽208內之軋延液中的軋延油是否仍符合軋延製程的規格需求，以確保軋延品質。 Since the saponification price can be used to judge the degree of deterioration of the oil, the online saponification price detecting device 104 is used to detect the saponification price of the rolling liquid in the rolling solution tank 208, and the rolling liquid in the rolling liquid tank 208 can be judged first. Whether the rolling oil in the product still meets the specifications of the rolling process to ensure the rolling quality.
數據處理與控制系統102收到線上皂化價檢測裝置104之軋延液的皂化價資訊後，將所檢測到的皂化價與預存之預設值或油皂化價與油劣化率之關係表比對判斷後，數據處理與控制系統102會產生對應之控制訊號與切換訊號。 After receiving the saponification price information of the rolling solution of the online saponification price detecting device 104, the data processing and control system 102 compares the detected saponification price with the pre-stored preset value or the relationship between the oil saponification price and the oil deterioration rate. After the determination, the data processing and control system 102 generates corresponding control signals and switching signals.
排放開關106設於軋延液槽208，其中排放開關106可控制軋延液槽208內之軋延液的排放與否。排放開關 106和數據處理與控制系統102訊號連接，以接受數據處理與控制系統102所傳來之切換訊號。舉例而言，排放開關106利用電性連接的方式來和數據處理與控制系統102訊號連接。然而，排放開關106亦可以藍牙等無線傳輸方式來和數據處理與控制系統102訊號連接。排放開關106配置以接收數據處理與控制系統102所傳來之切換訊號，並根據此切換訊號開啟或關閉。 The discharge switch 106 is disposed in the rolling liquid tank 208, wherein the discharge switch 106 can control the discharge of the rolling liquid in the rolling liquid tank 208. Drain switch The signal processing and control system 102 is coupled to the signal processing and control system 102 for receiving the switching signals from the data processing and control system 102. For example, the drain switch 106 is electrically coupled to the data processing and control system 102 by means of electrical connections. However, the drain switch 106 can also be connected to the data processing and control system 102 by wireless transmission means such as Bluetooth. The drain switch 106 is configured to receive a switching signal from the data processing and control system 102 and to turn it on or off based on the switching signal.
舉例而言，數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷獲得軋延液的皂化價低於預設值、或在關係表中所對應之油劣化率已超出製程規範時，所產生之切換訊號係開啟排放開關106。當排放開關106開啟時，可將軋延液槽208內之軋延液排放到廢油水處理系統，以在廢油水處理系統中進行必要之處理，藉此避免排放之軋延液汙染環境。 For example, the data processing and control system 102 determines, according to the detected saponification price, that the saponification price of the rolling solution is lower than a preset value, or the oil deterioration rate corresponding to the relationship table has exceeded the process. In the specification, the generated switching signal turns on the drain switch 106. When the discharge switch 106 is opened, the rolling liquid in the rolling liquid tank 208 can be discharged to the waste oil water treatment system to perform necessary treatment in the waste oil water treatment system, thereby preventing the discharged rolling liquid from polluting the environment.
另一方面，數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷獲得軋延液的皂化價高於或等於預設值、或在關係表中所對應之油劣化率並未超出製程規範時，所產生之切換訊號係使排放開關106維持關閉。當排放開關106關閉時，代表軋延液槽208內之軋延液符合軋研製程的規範，因而輸送至軋機200，來供軋延製程使用。 On the other hand, the data processing and control system 102 compares and determines the saponification price of the rolling solution to be higher than or equal to a preset value or an oil deterioration rate corresponding to the relationship table according to the detected saponification price. When the process specification is not exceeded, the resulting switching signal maintains the drain switch 106 closed. When the discharge switch 106 is closed, the rolling solution representing the rolling solution tank 208 conforms to the specifications of the rolling development process and is thus sent to the rolling mill 200 for use in the rolling process.
高壓水噴射裝置108和數據處理與控制系統102訊號連接，以接受數據處理與控制系統102所傳來之控制訊號。舉例而言，高壓水噴射裝置108利用電性連接的方式來和數據處理與控制系統102訊號連接。然而，高壓水噴 射裝置108亦可以藍牙等無線傳輸方式來和數據處理與控制系統102訊號連接。高壓水噴射裝置108配置以接收數據處理與控制系統102所傳來之控制訊號，並根據此控制訊號來決定是否對軋延設備200之過濾系統206內之軋延液的濾過物噴射補充水。 The high pressure water injection device 108 is coupled to the data processing and control system 102 for receiving control signals from the data processing and control system 102. For example, the high pressure water injection device 108 is electrically coupled to the data processing and control system 102 by means of electrical connections. However, high pressure water spray The transmitting device 108 can also be connected to the data processing and control system 102 by wireless transmission such as Bluetooth. The high pressure water injection device 108 is configured to receive a control signal from the data processing and control system 102 and, based on the control signal, determine whether to inject makeup water to the filtrate of the rolling fluid in the filtration system 206 of the rolling apparatus 200.
舉例而言，數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷獲得軋延液的皂化價低於預設值、或在關係表中所對應之油劣化率已超出製程規範時，所產生之控制訊號係不啟動高壓水噴射裝置108，因軋延液槽208內之軋延液已排放更新。 For example, the data processing and control system 102 determines, according to the detected saponification price, that the saponification price of the rolling solution is lower than a preset value, or the oil deterioration rate corresponding to the relationship table has exceeded the process. In the specification, the generated control signal does not activate the high pressure water injection device 108 because the rolling fluid in the rolling solution tank 208 has been discharged and updated.
另一方面，數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷後獲得軋延液的皂化價高於或等於預設值、或在關係表中所對應之油劣化率並未超出製程規範時，所產生之控制訊號係啟動高壓水噴射裝置108，以利用原來添加於軋延液槽208中的補充水來沖洗過濾系統206內之軋延液的濾過物。在一些例子中，高壓水噴射裝置108所使用之補充水的溫度可為從約25℃至約60℃。高壓水噴射裝置108所使用之補充水的溫度較佳可為從約50℃至約60℃，以利更有效的分離軋延油與鐵粉屑和雜質。 On the other hand, the data processing and control system 102 obtains, according to the detected saponification price, the saponification price of the rolling solution after the comparison and judgment is higher than or equal to a preset value, or the oil deterioration rate corresponding to the relationship table. When the process specification is not exceeded, the resulting control signal activates the high pressure water injection device 108 to flush the filtrate of the rolling fluid in the filtration system 206 with the makeup water originally added to the casting bath 208. In some examples, the temperature of the makeup water used by the high pressure water injection device 108 can range from about 25 °C to about 60 °C. The temperature of the make-up water used by the high pressure water injection device 108 may preferably be from about 50 ° C to about 60 ° C to facilitate more efficient separation of the rolling oil from the iron dust and impurities.
由於高壓水噴射裝置108可以具較大衝力與高於室溫的補充水來沖洗過濾系統206內軋延液的濾過物，因此可有效分離軋延液之濾過物中的軋延油與鐵粉屑和雜質。如此一來，可將軋延液之濾過物中的軋延油有效分離再利用，而可提升軋延液中之軋延油的利用效率，並可明顯減 少軋延液之油耗，且可大幅減少過濾後之油泥渣或沖洗液直接排到下游廢油水處理系統的量，進而可降低下游廢油水之處理製程的負荷，減少製程成本。 Since the high-pressure water jet device 108 can flush the filtrate of the rolling solution in the filtration system 206 with a larger impulse and supplemental water above room temperature, the rolling oil and the iron powder in the filtrate of the rolling solution can be effectively separated. Chips and impurities. In this way, the rolling oil in the filtrate of the rolling liquid can be effectively separated and reused, and the utilization efficiency of the rolling oil in the rolling liquid can be improved, and the rolling efficiency can be significantly reduced. The fuel consumption of the rolling mill is reduced, and the amount of the sludge sludge or the flushing liquid after filtration is directly discharged to the downstream waste oil water treatment system, thereby reducing the load of the downstream waste oil water treatment process and reducing the process cost.
請再次參照圖1，在一些特定例子中，軋延液之監控系統100更可選擇性地包含導電度檢測裝置110。導電度檢測裝置110和數據處理與控制系統102訊號連接。舉例而言，導電度檢測裝置110利用電性連接的方式來和數據處理與控制系統102訊號連接。另外，導電度檢測裝置110亦可以藍牙等無線傳輸方式來和數據處理與控制系統102訊號連接。導電度檢測裝置110同時也與軋延液槽208連接。導電度檢測裝置110配置以檢測軋延液槽208內之軋延液的導電度，並將檢測到之軋延液的導電度的資訊透過訊號傳送的方式傳遞給數據處理與控制系統102。 Referring again to FIG. 1, in some specific examples, the rolling fluid monitoring system 100 more selectively includes a conductivity detecting device 110. The conductivity detecting device 110 and the data processing and control system 102 are connected to each other. For example, the conductivity detecting device 110 is electrically connected to the data processing and control system 102 by means of electrical connection. In addition, the conductivity detecting device 110 can also be connected to the data processing and control system 102 by a wireless transmission method such as Bluetooth. The conductivity detecting device 110 is also connected to the rolling solution tank 208 at the same time. The conductivity detecting device 110 is configured to detect the conductivity of the rolling solution in the rolling solution tank 208, and transmit the information of the conductivity of the detected rolling solution to the data processing and control system 102 by means of signal transmission.
由於軋延液之導電度的高低可用以判斷軋延液中之鐵粉屑的含量多寡，因此利用導電度檢測裝置110來檢測軋延液槽208內之軋延液的導電度，可先判斷軋延液槽208內之軋延液是否仍符合軋延製程的規格需求，以確保軋延品質。 Since the conductivity of the rolling solution can be used to determine the amount of iron dust in the rolling solution, the conductivity detecting device 110 is used to detect the conductivity of the rolling liquid in the rolling solution tank 208, which can be judged first. Whether the rolling solution in the rolling solution tank 208 still meets the specification requirements of the rolling process to ensure the rolling quality.
數據處理與控制系統102收到導電度檢測裝置110之軋延液的導電度資訊後，將所接收到的導電度與預存之預設值比對判斷後，數據處理與控制系統102會產生對應之驅動訊號。 After the data processing and control system 102 receives the conductivity information of the rolling solution of the conductivity detecting device 110, and compares the received conductivity with the pre-stored preset value, the data processing and control system 102 responds. Drive signal.
舉例而言，數據處理與控制系統102根據所檢測到的導電度，經比對與判斷後獲得軋延液的導電度高於或 等於預設值時，所產生之驅動訊號係驅動數據處理與控制系統102，以控制線上皂化價檢測裝置104開始進行軋延液槽208內之軋延液的皂化價的檢測。另一方面，當數據處理與控制系統102根據所檢測到的導電度，經比對與判斷後獲得軋延液的導電度低於預設值時，所產生之驅動訊號係驅使數據處理與控制系統102來控制線上皂化價檢測裝置104維持待命但不檢測的狀態。 For example, the data processing and control system 102 obtains the electrical conductivity of the rolling solution higher than or after the comparison and judgment based on the detected conductivity. When the value is equal to the preset value, the generated driving signal drives the data processing and control system 102 to control the online saponification rate detecting device 104 to start the detection of the saponification price of the rolling solution in the rolling bath 208. On the other hand, when the data processing and control system 102 determines, based on the detected conductivity, that the conductivity of the rolling solution is lower than a preset value after comparison and judgment, the generated driving signal system drives data processing and control. The system 102 controls the on-line saponification rate detecting device 104 to maintain a state of standby but not detected.
可運用上述實施方式之軋延液的監控系統100來進行軋延設備200之軋延液的監控。請同時參照圖1與圖2，其中圖2係繪示依照本發明之一實施方式的一種軋延液之監控方法的流程圖。軋延液之監控方法300可用於監控軋延設備之軋延液，例如圖1所示之軋延設備200的軋延液的使用情形，藉以降低軋延液的油耗，而提升軋延液的使用效率，並大幅減少廢油水的處理量。軋延液一般包含軋延油與水、磨耗金屬粉，在金屬加工的軋延製程中，可幫助潤滑減摩與冷卻降溫。軋延設備200主要可例如包含依序設置之軋機202、髒液回收槽204、過濾系統206以及軋延液槽208，其中軋延液主要也是以此順序在軋延設備200中循環。 The monitoring system 100 of the rolling solution of the above embodiment can be used to monitor the rolling solution of the rolling apparatus 200. Please refer to FIG. 1 and FIG. 2 simultaneously. FIG. 2 is a flow chart showing a method for monitoring the rolling solution according to an embodiment of the present invention. The rolling liquid monitoring method 300 can be used to monitor the rolling solution of the rolling equipment, such as the use of the rolling liquid of the rolling equipment 200 shown in FIG. 1, thereby reducing the fuel consumption of the rolling liquid and increasing the rolling liquid. Use efficiency and significantly reduce the amount of waste oil water treated. The rolling solution generally includes rolling oil and water, and wear metal powder, which can help to reduce friction and cool down during the rolling process of metal processing. The rolling apparatus 200 can primarily comprise, for example, a rolling mill 202, a dirty liquid recovery tank 204, a filtration system 206, and a rolling bath 208, which are sequentially disposed, wherein the rolling fluid is also primarily circulated in the rolling apparatus 200 in this order.
在一些例子中，軋延液之監控方法300可運用如圖1所示之軋延液之監控設備100來進行。由於上述已介紹監控設備100之各裝置及其相互連接關係，故於此不再贅述。進行監控方法300時，可先進行步驟302，以利用監控設備100之線上皂化價檢測裝置104檢測軋延液槽208內之軋延液的皂化價。皂化價檢測裝置104完成軋延液槽208內 之軋延液之皂化價的檢測後，將檢測到之軋延液的皂化價的資訊透過訊號傳送的方式傳遞給數據處理與控制系統102。 In some examples, the rolling fluid monitoring method 300 can be performed using the rolling fluid monitoring apparatus 100 as shown in FIG. Since the devices of the monitoring device 100 and the interconnection relationship thereof have been described above, they will not be described again. When the monitoring method 300 is performed, step 302 may be first performed to detect the saponification price of the rolling liquid in the rolling solution tank 208 by the online saponification price detecting device 104 of the monitoring device 100. The saponification rate detecting device 104 completes the rolling solution tank 208 After the detection of the saponification price of the rolling solution, the information of the detected saponification price of the rolling solution is transmitted to the data processing and control system 102 by means of signal transmission.
由於皂化價可用以判斷軋延油的劣化程度，因此利用線上皂化價檢測裝置104來檢測軋延液槽208內之軋延液的皂化價，可先判斷軋延液槽208內之軋延液中的軋延油是否符合軋延製程的規格需求，以確保金屬胚的軋延品質。 Since the saponification price can be used to judge the degree of deterioration of the rolling oil, the online saponification price detecting device 104 is used to detect the saponification value of the rolling liquid in the rolling solution tank 208, and the rolling liquid in the rolling liquid tank 208 can be judged first. Whether the rolling oil in the roll meets the specifications of the rolling process to ensure the rolling quality of the metal blank.
在一些例子中，於步驟302之前，可先選擇性地以導電度檢測裝置110檢測軋延液槽208內之軋延液的導電度，並將檢測到之軋延液的導電度的資訊透過訊號傳送的方式傳遞給數據處理與控制系統102。由於軋延液之導電度可用以判斷軋延液中之鐵粉屑的含量，而鐵粉屑含量高代表軋延液潔淨度差，因此利用導電度檢測裝置110來檢測軋延液槽208內之軋延液的導電度，藉此可先判斷軋延液槽208內之軋延液是否仍符合軋延製程的規格需求。 In some examples, prior to step 302, the conductivity of the rolling solution in the rolling solution tank 208 may be selectively detected by the conductivity detecting device 110, and the information of the conductivity of the detected rolling solution may be transmitted through The manner in which the signals are transmitted is passed to the data processing and control system 102. Since the conductivity of the rolling solution can be used to judge the content of the iron dust in the rolling liquid, and the high iron powder content represents the poor cleanness of the rolling liquid, the conductivity detecting device 110 is used to detect the inside of the rolling liquid tank 208. The conductivity of the rolling solution can be used to determine whether the rolling solution in the rolling solution tank 208 still meets the specifications of the rolling process.
數據處理與控制系統102收到導電度檢測裝置110傳來之軋延液的導電度資訊後，將所檢測到的導電度與預存之預設值比對判斷後，數據處理與控制系統102會產生對應之驅動訊號。舉例而言，數據處理與控制系統102根據所接收之導電度，經比對與判斷後獲得軋延液的導電度高於或等於預設值時，所產生之驅動訊號係驅動數據處理與控制系統102，以控制線上皂化價檢測裝置104開始進行軋延液槽208內之軋延液的皂化價的檢測。藉此，可調控軋延液系統的導電度值至管制範圍內，而有利於穩定軋延液系統內的 鐵離子與鐵粉粒子的含量值。另一方面，當數據處理與控制系統102根據所檢測到的導電度，經比對與判斷後獲得軋延液的導電度低於預設值時，所產生之驅動訊號係驅動數據處理與控制系統102來控制線上皂化價檢測裝置104維持待命但不檢測的狀態。 After receiving the conductivity information of the rolling solution from the conductivity detecting device 110, the data processing and control system 102 compares the detected conductivity with the pre-stored preset value, and the data processing and control system 102 Generate the corresponding drive signal. For example, the data processing and control system 102 generates, according to the received conductivity, the driving signal driving data processing and control generated when the conductivity of the rolling liquid is higher than or equal to a preset value after comparison and judgment. The system 102 starts the determination of the saponification price of the rolling solution in the rolling bath 208 by the control line saponification rate detecting means 104. Thereby, the conductivity value of the rolling liquid system can be adjusted to within the control range, thereby facilitating the stabilization of the rolling liquid system. The content of iron ions and iron powder particles. On the other hand, when the data processing and control system 102 obtains the electrical conductivity of the rolling solution after the comparison and the judgment according to the detected conductivity, the generated driving signal driving data processing and control is generated. The system 102 controls the on-line saponification rate detecting device 104 to maintain a state of standby but not detected.
請再次參照圖1與圖2，完成軋延液槽208內之軋延液之皂化價的檢測後，可進行步驟304，利用數據處理與控制系統102接收來自線上皂化價檢測裝置104傳來之軋延液的皂化價。在一些例子中，可以利用線上皂化價檢測裝置104檢測軋延液槽208內之軋延液之皂化價前，先於數據處理與控制系統102中輸入油皂化價與油劣化率之關係表，以利數據處理與控制系統102進行皂化價的比對判斷。 Referring again to FIG. 1 and FIG. 2, after the detection of the saponification value of the rolling solution in the rolling solution tank 208 is completed, step 304 may be performed, and the data processing and control system 102 receives the from the online saponification price detecting device 104. The saponification price of the rolling solution. In some examples, the online saponification rate detecting device 104 can be used to detect the saponification price of the rolling solution in the rolling solution tank 208 prior to the input of the oil saponification price and the oil deterioration rate in the data processing and control system 102. The benefit data processing and control system 102 performs a comparison of the saponification prices.
數據處理與控制系統102收到線上皂化價檢測裝置104傳來之軋延液的皂化價資訊後，可進行步驟306，以將所檢測到的皂化價與預存之預設值、或油皂化價與油劣化率之關係表進行比對判斷。於比對判斷後，數據處理與控制系統102會產生對應之控制訊號與切換訊號。 After the data processing and control system 102 receives the saponification price information of the rolling solution from the online saponification price detecting device 104, step 306 may be performed to adjust the detected saponification price and the pre-stored preset value or the oil saponification price. The comparison table with the oil deterioration rate is compared and judged. After the comparison is determined, the data processing and control system 102 generates corresponding control signals and switching signals.
當數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷後所獲得之判斷結果為軋延液的皂化價高於或等於預設值、或在關係表中所對應之油劣化率並未超出製程規範時，數據處理與控制系統102根據判斷結果會產生之對應的切換訊號為使排放開關106維持關閉。此時，可進行步驟308，以利用數據處理與控制系統102傳送切換訊號給排放開關106，來使排放開關106維持關閉。當排放開 關106關閉時，代表軋延液槽208內之軋延液符合軋研製程的規範，因而可輸送至軋機200，來供軋延製程使用。 When the data processing and control system 102 determines, according to the detected saponification price, the result of the comparison and judgment is that the saponification price of the rolling solution is higher than or equal to a preset value, or the oil corresponding to the relationship table. When the degradation rate does not exceed the process specification, the data processing and control system 102 generates a corresponding switching signal according to the determination result to keep the discharge switch 106 closed. At this point, step 308 can be performed to utilize the data processing and control system 102 to transmit a switching signal to the drain switch 106 to maintain the drain switch 106 closed. When the discharge is on When the closing 106 is closed, the rolling solution in the rolling solution tank 208 conforms to the specifications of the rolling development process, and thus can be sent to the rolling mill 200 for use in the rolling process.
此外，當數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷後所獲得之判斷結果為軋延液的皂化價高於或等於預設值、或在關係表中所對應之油劣化率並未超出製程規範時，數據處理與控制系統102根據判斷結果同時也會產生之對應控制訊號為啟動高壓水噴射裝置108。此時，可進行步驟310，以利用數據處理與控制系統102傳送控制訊號給高壓水噴射裝置108，來驅動高壓水噴射裝置108，而利用原來添加於軋延液槽208中的補充水來沖洗過濾系統206內之軋延液體的濾過物。在一些例子中，高壓水噴射裝置108所使用之補充水的溫度可為從約25℃至約60℃。高壓水噴射裝置108所使用之補充水的溫度較佳可為從約50℃至約60℃，以利更有效的分離軋延油與鐵粉屑和雜質。 In addition, when the data processing and control system 102 determines, based on the detected saponification price, the saponification price obtained by comparing and judging is that the saponification price of the rolling solution is higher than or equal to a preset value, or corresponds to a relationship table. When the oil degradation rate does not exceed the process specification, the data processing and control system 102 also generates a corresponding control signal based on the determination result to activate the high pressure water injection device 108. At this time, step 310 may be performed to transmit the control signal to the high pressure water injection device 108 by the data processing and control system 102 to drive the high pressure water injection device 108 to be flushed with the supplementary water originally added to the rolling solution tank 208. Filtration of the rolling liquid within the filtration system 206. In some examples, the temperature of the makeup water used by the high pressure water injection device 108 can range from about 25 °C to about 60 °C. The temperature of the make-up water used by the high pressure water injection device 108 may preferably be from about 50 ° C to about 60 ° C to facilitate more efficient separation of the rolling oil from the iron dust and impurities.
由於高壓水噴射裝置108可提供較大衝力與高於室溫的補充水來沖洗過濾系統206內之軋延液的濾過物，因此可有效分離濾過物中的軋延油與鐵粉屑和雜質，而可將濾過物中的軋延油有效分離出來再回收利用。如此，可提升濾過物中之軋延油的利用效率，並可減少軋延液之油耗，且可大幅減少過濾後之油泥渣或沖洗液直接排到下游廢油水處理系統的量。故，可降低下游廢油水之處理製程的負荷，減少製程成本。 Since the high pressure water injection device 108 can provide a larger impulse and supplemental water above room temperature to flush the filtrate of the rolling solution in the filtration system 206, the rolling oil and iron dust and impurities in the filtrate can be effectively separated. The rolling oil in the filtrate can be effectively separated and recycled. In this way, the utilization efficiency of the rolling oil in the filtrate can be improved, the fuel consumption of the rolling liquid can be reduced, and the amount of the filtered sludge or the flushing liquid directly discharged to the downstream waste oil water treatment system can be greatly reduced. Therefore, the load of the downstream waste oil water treatment process can be reduced, and the process cost can be reduced.
另一方面，在步驟306中，當數據處理與控制系統102根據所檢測到的皂化價，經比對與判斷獲得軋延液的皂化價低於預設值、或在關係表中所對應之油劣化率已超出製程規範時，數據處理與控制系統102根據判斷結果會產生之對應的切換訊號為開啟排放開關106。此時，可進行步驟312，以利用數據處理與控制系統102傳送切換訊號給排放開關106，來開啟排放開關106。當排放開關106開啟時，可將軋延液槽208內之軋延液排放到廢油水處理系統，以在廢油水處理系統中進行必要之處理，藉此避免排放之軋延液汙染環境。此時，數據處理與控制系統102根據所檢測到的皂化價，所產生之控制訊號係不啟動高壓水噴射裝置108，因軋延液槽208內之軋延液已排放更新。 On the other hand, in step 306, when the data processing and control system 102 determines, based on the detected saponification price, the saponification price of the rolling solution is lower than a preset value or corresponds to the relationship table. When the oil degradation rate has exceeded the process specification, the data processing and control system 102 generates a corresponding switching signal according to the determination result to turn on the drain switch 106. At this point, step 312 can be performed to utilize the data processing and control system 102 to transmit a switching signal to the drain switch 106 to turn the drain switch 106 on. When the discharge switch 106 is opened, the rolling liquid in the rolling liquid tank 208 can be discharged to the waste oil water treatment system to perform necessary treatment in the waste oil water treatment system, thereby preventing the discharged rolling liquid from polluting the environment. At this point, based on the detected saponification price, the data processing and control system 102 does not activate the high pressure water injection device 108 because the rolling fluid in the rolling bath 208 has been discharged.
比較例(即沒有經過本發明之軋延液之監控系統與監控方法監控的例子)：從現場取樣三次經過濾系統中之磁分離器與濾紙過濾器過濾後之物質，即油汙泥，來進行檢測分析，其結果如下表1所示。 Comparative Example (i.e., an example of monitoring system and monitoring method without the rolling solution of the present invention): sampling from the field three times through the magnetic separator and the filter paper filter in the filtration system, that is, oil sludge, The analysis was carried out, and the results are shown in Table 1 below.
由分析結果可得知，比較例之第1次取樣之油汙泥的組成成分為60wt%軋延油、30wt%水以及10wt%鐵粉 屑。由此結果可知，過濾系統濾過磨耗鐵粉之效率尚有改善空間。而且，第1次取樣之軋延油經皂化價(SV)分析後，其皂化價值為173mg KOH/g。再經熱重分析儀(TGA)分析以及傅立葉紅外線光譜儀(FTIR)分析等進一步的檢測評估後，可知第1次取樣之軋延油與新鮮軋延油的品質相近。這樣的分析結果表示，過濾系統濾過物內之軋延油明顯還可供回收使用。 It can be known from the analysis results that the composition of the first sample of the oil sludge of the comparative example is 60 wt% rolling oil, 30 wt% water, and 10 wt% iron powder. Chips. From this result, it is known that there is room for improvement in the efficiency of the filtration system for filtering the iron powder. Further, the saponification value of the rolling oil of the first sampling after saponification (SV) analysis was 173 mg KOH/g. After further analysis and evaluation by thermogravimetric analysis (TGA) analysis and FTIR analysis, it is known that the quality of the first sampled rolling oil is similar to that of fresh rolling oil. The results of this analysis indicate that the rolling oil in the filtrate of the filtration system is clearly available for recycling.
比較例之第2次取樣之油汙泥的組成成分為58wt%軋延油、31wt%水以及11wt%鐵粉屑。而且，第2次取樣之軋延油經皂化價分析後，其皂化價值為160mg KOH/g。另外，比較例之第3次取樣之油汙泥的組成成分為52wt%軋延油、34wt%水以及14wt%鐵粉屑。第3次取樣之軋延油經皂化價分析後，其皂化價值為145mg KOH/g。由此可知，軋延液經回收使用後，其中之軋延油的皂化價下降。 The composition of the oil sludge of the second sampling of the comparative example was 58 wt% rolling oil, 31 wt% water, and 11 wt% iron dust. Further, after the second sampling of the rolling oil was analyzed by saponification, the saponification value was 160 mg KOH/g. Further, the composition of the oil sludge of the third sampling of the comparative example was 52% by weight of rolling oil, 34% by weight of water, and 14% by weight of iron powder. After the third sample of the rolling oil was analyzed by saponification, the saponification value was 145 mg KOH/g. It can be seen from this that after the rolling solution is recycled, the saponification price of the rolling oil is lowered.
實施例(即經過本發明之軋延液之監控系統與監控方法監控的例子)：取樣三次經過濾系統中之磁分離器與濾紙過濾器濾過後之油汙泥來進行檢測分析，其結果如下表2所示。 Embodiment (that is, an example of monitoring by the monitoring system and monitoring method of the rolling solution of the present invention): sampling and analyzing the oil sludge filtered by the magnetic separator and the filter paper filter in the filtration system for the detection and analysis, and the results are as follows: 2 is shown.
由分析結果可得知，實施例之第1次取樣之油汙泥的組成成分為12wt%軋延油、29wt%水以及59wt%鐵粉屑。由此結果可知，經本發明實施例監控處理後，軋延油的回收再利用率可達80%以上。在上表2中，第1次取樣之軋延油的皂化價值為177mg KOH/g，第2次取樣之軋延油的皂化價值為163mg KOH/g，第3次取樣之軋延油的皂化價值為150mg KOH/g。 As can be seen from the analysis results, the composition of the oil sludge of the first sampling of the examples was 12 wt% rolling oil, 29 wt% water, and 59 wt% iron dust. From this result, it can be seen that after the monitoring and treatment of the embodiment of the present invention, the recovery and utilization rate of the rolling oil can reach 80% or more. In the above Table 2, the saponification value of the rolling oil of the first sampling was 177 mg KOH/g, and the saponification value of the rolling oil of the second sampling was 163 mg KOH/g, and the saponification of the rolling oil of the third sampling was performed. The value is 150 mg KOH/g.
請參見下表3，其列示數個軋延液系統之皂化價檢測值與對應試片之表面狀況。 Please refer to Table 3 below, which shows the saponification value of several rolling system and the surface condition of the corresponding test piece.
在上表3中，試片Al係採新軋延液來進行軋延，且由表3可知新軋延液之皂化價檢測值為180mg KOH/g。此外，在表3中，油品劣化率定義為：油品劣化率(%)=[(新軋延液皂化價檢測值-已使用之軋延液皂化價檢測值)÷新軋延液皂化價檢測值]×100。 In the above Table 3, the test piece Al was subjected to rolling with a new rolling solution, and it was found from Table 3 that the saponification value of the new rolling solution was 180 mg KOH/g. In addition, in Table 3, the oil deterioration rate is defined as: oil deterioration rate (%) = [(new rolling solution saponification price detection value - used rolling solution saponification price detection value) new rolling solution saponification Price detection value] × 100.
由上表1至表3可知，隨著軋延液的使用次數增加，其中的軋延油的皂化價降低，且軋延油的油品劣化率提高。而且，根據表3之例子，軋延油之皂化價在低於136mg KOH/g時，試片表面就開始出現刮痕，此時可考慮更換軋延液。 As is apparent from the above Tables 1 to 3, as the number of times of use of the rolling solution increases, the saponification price of the rolling oil therein decreases, and the oil deterioration rate of the rolling oil increases. Further, according to the example of Table 3, when the saponification price of the rolling oil is less than 136 mg KOH/g, scratches appear on the surface of the test piece, and replacement of the rolling solution may be considered at this time.
由上述之實施方式可知，本發明之一優點就是因為本發明之軋延液之監控系統與監控方法偵測軋延液之皂化價來判斷軋延液的更換時機，並搭配利用高壓水噴射裝置，且以補充水來沖洗過濾系統內濾過物之軋延油，藉此可有效分離過濾系統內濾過物中之鐵粉屑與軋延油，如此一來，可在確保軋延金屬表面的品質下，提升軋延液中之軋延油的利用效率，並可大幅減少下游之廢油水處理系統處理廢油泥渣的量，故可降低製程成本。 It can be seen from the above embodiments that one advantage of the present invention is that the monitoring system and the monitoring method of the rolling solution of the present invention detect the saponification price of the rolling liquid to judge the replacement time of the rolling liquid, and cooperate with the high pressure water spraying device. And the supplemental water is used to rinse the rolling oil of the filtrate in the filtration system, thereby effectively separating the iron powder and the rolling oil in the filtrate in the filtration system, thereby ensuring the quality of the rolled metal surface. The utility model can improve the utilization efficiency of the rolling oil in the rolling liquid, and can greatly reduce the amount of waste oil sludge treated by the downstream waste oil water treatment system, thereby reducing the process cost.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何在此技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 While the present invention has been described above by way of example, it is not intended to be construed as a limitation of the scope of the invention.
