請參照圖1，其係繪示根據本發明實施例之軋輥檢驗系統100之功能方塊圖，軋輥檢驗系統100包含軋輥研磨資料庫110、軋延資料庫120、軋輥管理模組130以及軋輥輥形檢驗模組140。軋輥研磨資料庫110係用以儲存複數個軋輥組標準資料，以供軋輥研磨製程使用。每個軋輥組標準資料係對應至一個軋輥組，且包含一個標準上輥外形以及一個標準下輥外形。舉例而言，在對軋輥進行研磨時，軋輥研磨資料庫110可根據使用者需求來提供一個軋輥組標準資料的標準上輥外形和標準下輥外形，以研磨出具有標準上輥外形的上輥以及具有標準下輥外形的下輥。在本發明之一實施例中，標準上輥外形包含複數個寬度對半徑的資料點，這些資料點可構成標準上輥外形。類似地，標準下輥外形也包含複數個寬度對半徑的資料點，這些資料點可構成標準下輥外形。 Please refer to FIG. 1, which shows a functional block diagram of a roll inspection system 100 according to an embodiment of the present invention. The roll inspection system 100 includes a roll grinding database 110, a rolling database 120, a roll management module 130, and a roll profile. Inspection module 140. The roll grinding database 110 is used to store a plurality of roll group standard data for use in the roll grinding process. Each roll group standard data corresponds to a roll group, and includes a standard upper roll profile and a standard lower roll profile.

Similarly, the standard bottom roll profile also contains multiple width-to-radius data points, which can constitute the standard bottom roll profile.

再者，軋輥研磨資料庫110亦用以儲存複數個軋輥組的軋輥組真實資料。這些軋輥組真實資料包含真實上輥外形以及真實下輥外形。舉例而言，在軋延機台利用研 磨完成的軋輥組來進行軋延製程時，軋延機台會相應地記錄軋輥組上輥和下輥的真實上輥外形以及真實下輥外形，並將其儲存於軋輥研磨資料庫110中。在本發明之一實施例中，真實上輥外形包含複數個寬度對半徑的資料點，這些資料點可構成真實上輥外形。類似地，真實下輥外形也包含複數個軋輥寬度對軋輥半徑的資料點，這些資料點可構成真實下輥外形。在本發明之實施例中，軋延製程的工輥可為上輥或下輥。 Furthermore, the roll grinding database 110 is also used to store the actual data of the roll sets of a plurality of roll sets. The real data of these roll sets include the real top roll shape and the real bottom roll shape. For example, the use of research When the finished roll set is used for the rolling process, the rolling machine will record the real top roll shape and the real bottom roll shape of the top and bottom rolls of the roll set accordingly, and store them in the roll grinding database 110. In an embodiment of the present invention, the actual upper roller profile includes a plurality of width-to-radius data points, and these data points can constitute the true upper roller profile. Similarly, the real bottom roll profile also includes a plurality of data points of roll width versus roll radius, and these data points can constitute the real bottom roll profile. In the embodiment of the present invention, the work roll of the rolling process may be an upper roll or a lower roll.

軋輥管理模組130係電性連接至軋輥研磨資料庫110和軋延資料庫120，以根據使用者需求來擷取軋輥研磨資料庫110的資料，並將其傳送至軋輥輥形檢驗模組140，以檢驗軋延設備的軋輥組(以下稱為目標軋輥組)是否有異常。舉例而言，如果使用者覺得軋延製程進行得不順利(例如產品出現異常)，使用者可利用軋輥管理模組130來取得目標軋輥組的軋輥組真實資料和軋輥組標準資料，並將其傳送至軋輥輥形檢驗模組140。如此，使用者可透過軋輥輥形檢驗模組140來檢驗目標軋輥組是否異常。 The roll management module 130 is electrically connected to the roll grinding database 110 and the rolling database 120 to retrieve the data of the roll grinding database 110 according to user needs and send it to the roll shape inspection module 140 , To check whether the roll set of the rolling equipment (hereinafter referred to as the target roll set) is abnormal. For example, if the user feels that the rolling process is not going well (for example, the product is abnormal), the user can use the roll management module 130 to obtain the real data of the target roll set and the standard data of the roll set. Transfer to the roll shape inspection module 140. In this way, the user can check whether the target roll set is abnormal through the roll shape inspection module 140.

在本發明之一實施例中，當軋延製程進行得不順利時，使用者可輸入要查詢的時間區間至軋輥管理模組130，此時間區間可根據目標軋輥組之軋延開始時間來決定，但本發明之實施例並不受限於此。接著，軋輥管理模組130會根據此時間區間以及軋延資料庫120中的軋延資料來檢查軋延設備上的軋輥號碼是否發生變化。當軋輥號碼發生 變化時，軋輥管理模組130判斷有換輥事件發生，並自動抓取換輥後的第一個鋼捲編號，再找到對應的軋輥編號。然後，軋輥管理模組130可基於此軋輥編號以及此鋼捲的軋延時間從軋輥研磨資料庫110中擷取對應的軋輥組標準資料和軋輥組真實資料。如此，使用者便可根據軋延資料庫120中所儲存的軋延資料來從軋輥研磨資料庫110獲取目標軋輥組的軋輥組真實資料和軋輥組標準資料。 In an embodiment of the present invention, when the rolling process does not go smoothly, the user can input the time interval to be queried to the roll management module 130, and this time interval can be determined according to the rolling start time of the target roll group However, the embodiments of the present invention are not limited to this. Then, the roll management module 130 checks whether the roll number on the rolling equipment has changed according to this time interval and the rolling data in the rolling database 120. When the roll number occurs During the change, the roll management module 130 determines that a roll change event has occurred, and automatically grabs the first coil number after the roll change, and then finds the corresponding roll number. Then, the roll management module 130 can retrieve the corresponding roll set standard data and the actual roll set data from the roll grinding database 110 based on the roll number and the rolling time of the steel coil. In this way, the user can obtain the actual roll set data and the standard roll set data of the target roll set from the roll grinding database 110 according to the rolling data stored in the rolling database 120.

在本發明之其他實施例中，軋輥研磨資料庫110和軋延資料庫120可使用統一格式的識別碼(ID)來識別各個軋輥，如此軋輥管理模組130可直接透過此共通識別碼來從軋輥研磨資料庫110中擷取目標軋輥組所對應的軋輥組標準資料和軋輥組真實資料。 In other embodiments of the present invention, the roll grinding database 110 and the rolling database 120 can use a uniform format identification code (ID) to identify each roll, so that the roll management module 130 can directly use the common identification code to access The roll grinding database 110 retrieves the standard data of the roll set and the real data of the roll set corresponding to the target roll set.

軋輥輥形檢驗模組140係用以進行檢測步驟，以對軋輥管理模組130所傳送之軋輥組標準資料與軋輥組真實資料進行曲線擬合，並判斷目標軋輥組是否發生異常。 The roll profile inspection module 140 is used to perform a detection step to perform curve fitting on the standard data of the roll set transmitted by the roll management module 130 and the real data of the roll set, and determine whether the target roll set is abnormal.

請參照圖2，其係繪示根據本發明實施例之軋輥檢驗方法200的流程示意圖。在軋輥檢驗方法200中，首先進行步驟210和220，以利用軋輥管理模組130從軋輥研磨資料庫110取得目標軋輥組之軋輥組標準資料以及軋輥組真實資料。接著，進行步驟230，以利用軋輥輥形檢驗模組140來進行檢測步驟，以對軋輥組標準資料與軋輥組真實資料進行曲線擬合，並判斷目標軋輥組是否發生異常。 Please refer to FIG. 2, which is a schematic flowchart of a roll inspection method 200 according to an embodiment of the present invention. In the roll inspection method 200, steps 210 and 220 are first performed to use the roll management module 130 to obtain the roll set standard data and the actual roll set data of the target roll set from the roll grinding database 110. Then, step 230 is performed to use the roll profile inspection module 140 to perform a detection step to perform curve fitting on the standard data of the roll set and the real data of the roll set, and determine whether the target roll set is abnormal.

請參照圖3，其係繪示軋輥管理模組130所進行 之檢測步驟300的流程示意圖。在檢測步驟300中，首先進行步驟310，以根據軋輥組標準資料來計算工輥之複數個橫移量所對應之複數個標準等效冠高，以獲得標準特徵曲線。例如，在步驟310中，首先對軋輥組標準資料所包含的資料點進行多項次曲線擬合，以獲得對應標準上輥外形的上輥曲線C1和對應標準下輥外形的下輥曲線C2，及其方程式，如圖4a和4b所示。接著，根據上輥曲線方程式和下輥曲線方程式來計算工輥(在本實施例中為上輥)在複數個不同橫移量下所對應之不同輥縫形狀，如圖4c、圖4d與圖4e所示。然後，為計算不同橫移量下所對應之開度曲線，可將上輥曲線方程式和下輥曲線方程式相減，並將相減後的方程式降階至2次曲線，如圖4f、圖4g與圖4h之虛線所示。接著，將軋輥中央的位置數據以及軋輥邊緣的位置數據帶入前述之2次曲線方程式，並再將其降階，即可獲得代表工輥橫移量與等效冠高之線性關係的標準特徵曲線。 Please refer to Figure 3, which shows the roll management module 130 performed Schematic diagram of the flow of the detection step 300. In the detection step 300, step 310 is first performed to calculate a plurality of standard equivalent crown heights corresponding to a plurality of lateral displacements of the work roll according to the standard data of the roll group to obtain a standard characteristic curve. For example, in step 310, firstly perform polynomial curve fitting on the data points contained in the standard data of the roll set to obtain the upper roll curve C1 corresponding to the standard upper roll profile and the lower roll curve C2 corresponding to the standard lower roll profile, and The equations are shown in Figures 4a and 4b. Then, according to the upper roll curve equation and the lower roll curve equation, calculate the different roll gap shapes corresponding to the work roll (in this embodiment, the upper roll) under a plurality of different traverse amounts, as shown in Figure 4c, Figure 4d and Figures 4c, 4d, and 4c. Shown in 4e. Then, in order to calculate the opening curve corresponding to different lateral displacements, the upper roller curve equation and the lower roller curve equation can be subtracted, and the subtracted equation can be reduced to a second-order curve, as shown in Figure 4f and Figure 4g This is shown by the dashed line in Figure 4h. Then, bring the position data of the center of the roll and the position data of the edge of the roll into the aforementioned quadratic curve equation, and then reduce the order to obtain the standard feature representing the linear relationship between the work roll traverse and the equivalent crown height curve.

在步驟310後，接著進行步驟320，以根據軋輥組真實資料來計算工輥之複數個橫移量所對應之複數個真實等效冠高，以獲得真實特徵曲線。在本實施例中，步驟320係類似於步驟310，其亦對軋輥組真實資料所包含的資料點進行多項次曲線擬合，並進行相似的計算步驟，以獲得代表工輥橫移量與等效冠高之線性關係的真實特徵曲線。其中，步驟320亦會計算不同橫移量下所對應之開度曲線，如圖4f、圖4g與圖4h之實線所示。 After step 310, step 320 is then performed to calculate a plurality of true equivalent crown heights corresponding to a plurality of lateral displacements of the work roll according to the actual data of the roll group, so as to obtain a true characteristic curve. In this embodiment, step 320 is similar to step 310, which also performs polynomial curve fitting on the data points contained in the real data of the roll group, and performs similar calculation steps to obtain the representative work roll traverse amount and etc. The true characteristic curve of the linear relationship of the effect crown. Among them, step 320 also calculates the opening curve corresponding to different lateral displacements, as shown by the solid lines in FIG. 4f, FIG. 4g, and FIG. 4h.

另外，本領域技術人員應可知，若目標軋輥組的上輥和下輥為對稱輥形，則前述之步驟310和320可相應地簡化。 In addition, those skilled in the art should know that if the upper roll and the lower roll of the target roll set are symmetrical, the aforementioned steps 310 and 320 can be simplified accordingly.

然後，進行步驟330，以計算標準特徵曲線FC1之斜率與真實特徵曲線FC2之斜率之間斜率差值，如圖4i所示，其中橫軸為橫移量，縱軸為冠高。由圖4i可知，標準特徵曲線FC1和真實特徵曲線FC2為直線，且斜率並非完全相同。實際上，考慮軋輥研磨製程本身可能的誤差，標準特徵曲線FC1和真實特徵曲線FC2的斜率會有稍微的差距。在本發明之實施例中，提供第一預設閥值來供使用者判斷誤差是否過大。在本實施例中，第一預設閥值為10%，但本發明之實施例並不受限於此。 Then, step 330 is performed to calculate the slope difference between the slope of the standard characteristic curve FC1 and the slope of the true characteristic curve FC2, as shown in FIG. 4i, where the horizontal axis is the amount of lateral displacement and the vertical axis is the crown height. It can be seen from Fig. 4i that the standard characteristic curve FC1 and the real characteristic curve FC2 are straight lines, and the slopes are not completely the same. In fact, considering the possible errors of the roll grinding process itself, the slope of the standard characteristic curve FC1 and the true characteristic curve FC2 will be slightly different. In the embodiment of the present invention, a first preset threshold is provided for the user to determine whether the error is too large. In this embodiment, the first preset threshold value is 10%, but the embodiment of the present invention is not limited to this.

接著，進行步驟340，以計算斜率差值與標準特徵曲線之比值，並判斷此比值是否大於第一預設閥值。當此比值大於第一預設閥值時，判斷真實特徵曲線FC2所對應之真實輥縫形狀不符合標準特徵曲線FC1所對應之標準輥縫形狀。意即，軋輥輥形檢驗模組140所檢驗之目標軋輥組有異常。 Then, step 340 is performed to calculate the ratio of the slope difference to the standard characteristic curve, and to determine whether the ratio is greater than the first preset threshold. When the ratio is greater than the first preset threshold, it is determined that the real roll gap shape corresponding to the real characteristic curve FC2 does not conform to the standard roll gap shape corresponding to the standard characteristic curve FC1. That is, the target roll group inspected by the roll profile inspection module 140 is abnormal.

另外，本發明實施例亦提供第二預設閥值來供使用者判斷是否需要對軋延製程進行調整。例如，進行步驟350，以判斷前述之比值是否小於第二預設閥值。當前述之比值小於第二預設閥值時，判斷真實特徵曲線FC2所對應之真實輥縫形狀符合標準特徵曲線FC1所對應之標準輥縫形狀，因此軋延製程的程控系統可直接使用預設之控制參數來進 行軋延製程。 In addition, the embodiment of the present invention also provides a second preset threshold for the user to determine whether the rolling process needs to be adjusted. For example, step 350 is performed to determine whether the aforementioned ratio is less than the second preset threshold. When the aforementioned ratio is less than the second preset threshold, it is judged that the real roll gap shape corresponding to the real characteristic curve FC2 matches the standard roll gap shape corresponding to the standard characteristic curve FC1, so the program control system of the rolling process can directly use the preset The control parameters come in Line rolling process.

然而，當前述之比值小於第一預設閥值且大於第二預設閥值時，進行步驟360，以根據軋輥組真實資料所包含的資料點來進行迴歸計算，以獲得工輥的真實迴歸曲線。例如，若工輥為上輥，則根據真實上輥外形的資料點，來進行迴歸計算，以獲得真實上輥外形的迴歸曲線方程式。又例如，若工輥為下輥，則根據真實下輥外形的資料點，來進行迴歸計算，以獲得代表真實下輥外形的迴歸曲線方程式。接著，進行步驟370，將真實迴歸曲線傳送至軋延製程的程控系統，以於軋延設備利用目標軋輥組來進行軋延時，控制此軋延設備來根據真實迴歸曲線控制工輥之移動。例如，軋輥輥形檢驗模組140可將工輥的真實迴歸曲線方程式的係數傳送至軋延製程的程控系統，如此程控系統根據這些係數來調整軋延製程的控制參數，以改善軋延製程。在本實施例中，第二預設閥值為6%，但本發明之實施例並不受限於此。 However, when the aforementioned ratio is less than the first preset threshold and greater than the second preset threshold, step 360 is performed to perform regression calculation based on the data points contained in the real data of the roll group to obtain the true regression of the work roll curve. For example, if the work roll is the upper roll, the regression calculation is performed based on the data points of the real upper roll shape to obtain the regression curve equation of the real upper roll shape. For another example, if the work roll is the bottom roll, a regression calculation is performed based on the data points of the real bottom roll shape to obtain a regression curve equation representing the real bottom roll shape. Next, proceed to step 370 to transmit the true regression curve to the program control system of the rolling process, so that the rolling equipment uses the target roll set to delay the rolling, and the rolling equipment is controlled to control the movement of the work rolls according to the true regression curve. For example, the roll shape inspection module 140 can transmit the coefficients of the true regression curve equation of the work roll to the program control system of the rolling process, so that the program control system adjusts the control parameters of the rolling process according to these coefficients to improve the rolling process. In this embodiment, the second preset threshold value is 6%, but the embodiment of the present invention is not limited to this.
