Abstract
Description
本發明係關於提升油品極壓性與乳化性的金屬加工油品添加劑，特別是關於一種用於軋延油提升油品極壓性與乳化性的金屬加工油品添加劑。The present invention relates to a metalworking oil additive for improving the extreme pressure and emulsification of oil products, and in particular to a metalworking oil additive for improving the extreme pressure and emulsification of rolling oil.
軋鋼廠根據產品規格的不同，於生產產品時之軋製負荷通常約介於1000至2500噸之間。一般而言，軋製過程通常會噴灑軋延乳化液，以同時確保冷卻與潤滑所需，俾利鋼材後續加工程序。再者，軋延油之特性需求，如表面的形變程度（油品潤滑性）、潔淨程度（油品揮發性）及防銹性均需同時兼顧。此外，因軋延乳化液中的油品濃度通常僅約為2至7wt%之間，其多數仍為水分，因此軋製過程中之鋼板冷卻需求通常較為穩定。然而，在潤滑的要求上，會因為軋製不同的鋼品組合而有不同的需求標準。Depending on the product specifications, the rolling load of steel rolling mills during product production is usually between 1,000 and 2,500 tons. Generally speaking, rolling emulsion is usually sprayed during the rolling process to ensure cooling and lubrication at the same time, so as to facilitate the subsequent processing of steel. In addition, the characteristics of rolling oil, such as surface deformation (oil lubricity), cleanliness (oil volatility) and rust resistance, must be taken into account at the same time. In addition, because the oil concentration in the rolling emulsion is usually only about 2 to 7wt%, most of it is still water, so the cooling demand of the steel plate during the rolling process is usually more stable. However, the lubrication requirements vary depending on the combination of steel products being rolled.
在非方向性電磁鋼捲的軋製上，因高品級電磁鋼捲之含矽量較高，導致鋼板較脆且硬度提升。因此，採用一般工輥軋製時，軋延機之軋製負荷通常會超出操作上限，尤其在起、完軋之低速軋延段的荷重更為明顯。因此，常需強化油品潤滑性以降低軋製負荷。In the rolling of non-directional electromagnetic steel coils, the high-grade electromagnetic steel coils have a higher silicon content, which makes the steel plate more brittle and hard. Therefore, when using general roller rolling, the rolling load of the rolling mill usually exceeds the upper limit of the operation, especially in the low-speed rolling section of the start and end of rolling. Therefore, it is often necessary to enhance the lubricity of the oil to reduce the rolling load.
此外，油品應用於鋼品軋製時係為乳化形態。因此，使用過程中之乳化形態的維持亦甚為重要。因為乳化形態的過度變化即會影響軋延的穩定性。In addition, oil is in emulsified form when used in steel rolling. Therefore, it is also very important to maintain the emulsified form during use, because excessive changes in the emulsified form will affect the stability of rolling.
現有商業用之電磁鋼捲軋延油品均需要添加高劑量的極壓添加劑方能提供高度的極壓性。然而，因極壓添加劑的反應活性較大，過量的添加通常會導致鋼品表面的品質問題。再者，亦會影響油品的乳化安定性而導致軋延品質的不佳。Existing commercial electromagnetic steel rolling oils require the addition of high doses of extreme pressure additives to provide high extreme pressure properties. However, due to the high reactivity of extreme pressure additives, excessive addition usually leads to quality problems on the surface of steel products. Furthermore, it will also affect the emulsification stability of the oil and lead to poor rolling quality.
因此，有必要提供一種同時提升油品極壓性與乳化性的金屬加工油品添加劑，以解決習用技術所存在的問題。Therefore, it is necessary to provide a metalworking oil additive that can simultaneously enhance the extreme pressure properties and emulsification properties of the oil to solve the problems existing in the conventional technology.
本發明之一目的在於一種同時提升油品極壓性與乳化性的金屬加工油品添加劑，可在低添加劑量的前提下，軋製難軋板材，並且在軋製過程中的油品乳化特性亦甚為穩定，進而強化了鋼品生產的穩定性。One of the purposes of the present invention is to provide a metalworking oil additive that simultaneously improves the extreme pressure and emulsification properties of the oil, so that difficult-to-roll plates can be rolled with a low additive dosage, and the emulsification properties of the oil during the rolling process are also very stable, thereby enhancing the stability of steel production.
本發明之一目的在於提供一種同時提升油品極壓性與乳化性的金屬加工油品添加劑，在約5%重量百分比的添加劑量下，即可達到4球燒熔負重約為800kgf之程度。One of the purposes of the present invention is to provide a metalworking oil additive that simultaneously improves the extreme pressure and emulsification properties of the oil, and at an additive dosage of about 5% by weight, a 4-ball sintered negative weight of about 800 kgf can be achieved.
本發明又一目的在於提供一種同時提升油品極壓性與乳化性的金屬加工油品添加劑，添加於軋延油中時，其軋延力降低幅度可達20%以上。Another object of the present invention is to provide a metalworking oil additive that simultaneously improves the extreme pressure and emulsification properties of the oil. When added to rolling oil, the rolling force can be reduced by more than 20%.
本發明再一目的在於提供一種同時提升油品極壓性與乳化性的金屬加工油品添加劑，當以乳化型態進行金屬加工時，則加工前、後之油滴粒徑變化幅度小於2%。Another object of the present invention is to provide a metal processing oil additive that simultaneously improves the extreme pressure and emulsification properties of the oil.

表1列出本發明之實施例及比較例的添加劑中的各成分（環烷基基礎油、石油溶劑、石油烷基苯磺酸鹽及硫系極壓添加劑）的含量比例，其比例單位為重量百分比（wt%）。
本發明之實施例1之詳細製備流程如下所述：於定量燒杯中，首先置入70克的環烷基基礎油，而後再依序加入20克的溶劑（例如，礦物油），再加入5克的石油烷基苯磺酸鈣以及5克的硫系極壓添加劑，以形成一添加劑混合液。同樣地，比較例1至8與實施例2至17之添加劑製備流程大致如實施例1所述，不同之處在於各實施例之添加劑成分以及各成分含量。The detailed preparation process of Example 1 of the present invention is as follows: 70 grams of cycloalkyl base oil is first placed in a quantitative beaker, and then 20 grams of solvent (e.g., mineral oil) is added in sequence, and then 5 grams of petroleum alkylbenzene sulfonate calcium and 5 grams of sulfur-based extreme pressure additive are added to form an additive mixture. Similarly, the additive preparation processes of Comparative Examples 1 to 8 and Examples 2 to 17 are roughly the same as those of Example 1, and the difference lies in the additive components and the content of each component in each example.
表2所示比較例1至7及實施例1至17即為表1中之比較例1至7或實施例1至17製成之添加劑以10wt%之重量比例添加於軋延油1中之極壓特性與乳化穩定狀況結果比較；表2所示實施例18、19、20為表1中之實施例1分別以5、8、13 wt%添加於軋延油1中之極壓特性與乳化穩定狀況結果比較；表2所示實施例21、22為將10 wt%之實施例1分別添加於軋延油2、3中之極壓特性與乳化穩定狀況結果比較。
本發明採用4球極壓測試儀比較各測試油種之極壓性，測試條件為每分鐘轉速1800轉（revolutions per minute，rpm）、歷時10秒，以記錄燒熔負重及最大無卡咬負重，其結果如表2所示。由表2可得知以實施例1之燒熔點負重（welding load）與最大無卡咬負重（Last non-seizure load）分別為大於800及250kgf。本發明實施例之結果均遠優於原始油種（軋延油1）所呈現的燒熔荷重（160 kgf）與最大無卡咬負重（63 kgf）。與比較例1~7之測試結果相比，可知添加劑需同時存有環烷基基礎油、溶劑、石油烷基苯磺酸鹽及硫系極壓添加劑，方可有極壓性的複合效果。The present invention uses a 4-ball extreme pressure tester to compare the extreme pressure of each test oil type. The test conditions are 1800 revolutions per minute (rpm) and 10 seconds to record the melting load and the maximum non-seizure load. The results are shown in Table 2. From Table 2, it can be seen that the melting load (welding load) and the maximum non-seizure load (Last non-seizure load) of Example 1 are greater than 800 and 250 kgf respectively. The results of the embodiments of the present invention are far better than the melting load (160 kgf) and the maximum non-seizure load (63 kgf) presented by the original oil type (rolling oil 1). Compared with the test results of Comparative Examples 1 to 7, it can be seen that the additive must contain cycloalkyl base oil, solvent, petroleum alkylbenzene sulfonate and sulfur-based extreme pressure additives at the same time to achieve an extreme pressure composite effect.
再者，由表2中本發明的實施例1至7得知，環烷基基礎油在添加劑產品的比例介於20至70wt%均有明顯的極壓促進效果，較佳地環烷基基礎油大於40wt%會有較佳的效果。Furthermore, it can be seen from Examples 1 to 7 of the present invention in Table 2 that the cycloalkyl base oil has a significant extreme pressure promoting effect when the proportion of the additive product is between 20 and 70 wt %, and preferably the cycloalkyl base oil is greater than 40 wt % to achieve a better effect.
表2中本發明的實施例7至10則顯示石油烷基苯磺酸鹽在添加劑產品的比例介於1.5至8.5wt%均有明顯的極壓促進效果，較佳地石油烷基苯磺酸鹽大於3.5wt%會有較佳的效果。Examples 7 to 10 of the present invention in Table 2 show that the proportion of petroleum alkylbenzene sulfonate in the additive product is between 1.5 and 8.5 wt % and has a significant extreme pressure promoting effect. Preferably, the petroleum alkylbenzene sulfonate is greater than 3.5 wt % to achieve a better effect.
表2中本發明的實施例1、11、12顯示環烷基基礎油的黏度會影響極壓性的複合結果，環烷基基礎油的黏度介於22至110cSt（@40℃）均有明顯的極壓促進效果，較佳地是環烷基基礎油的黏度大於50cSt會有較佳的促進效果。Examples 1, 11, and 12 of the present invention in Table 2 show that the viscosity of the cycloalkyl base oil affects the composite result of extreme pressure. The viscosity of the cycloalkyl base oil between 22 and 110 cSt (@40°C) has a significant extreme pressure promoting effect. Preferably, the viscosity of the cycloalkyl base oil is greater than 50 cSt to have a better promoting effect.
表2中本發明的實施例12至17顯示添加劑之各類組成更換為不同廠牌之料源時，並不影響極壓性的複合效果。Examples 12 to 17 of the present invention in Table 2 show that when the various types of additives are replaced with different brands of sources, the composite effect of the extreme pressure is not affected.
表2中本發明的實施例18至20為將為實施例1依不同添加劑量添加至軋延油1中（5至13wt%）。較佳地當實施例1的添加劑添加至軋延油1的比例大於7wt%時，會有較佳的促進效果。In Table 2, Examples 18 to 20 of the present invention are Example 1 added to rolling oil 1 in different amounts (5 to 13 wt%). Preferably, when the proportion of the additive of Example 1 added to rolling oil 1 is greater than 7 wt%, a better promotion effect will be achieved.
表2中本發明的實施例21至22為將實施例1添加於軋延油2與軋延油3中，亦可明顯得知極壓性的促進效應。In Table 2, Examples 21 to 22 of the present invention are obtained by adding Example 1 to Rolling Oil 2 and Rolling Oil 3, and the effect of promoting the extreme pressure can also be clearly seen.
此外，所配好之測試油種若以乳化型態（水：油為95：5 wt%）進行測試，則軋延液在4球磨潤前、後之乳化粒徑的變化幅度均遠低於原用軋延油，顯示本發明的金屬加工油品添加劑的使用有助於強化乳化安定性。In addition, when the prepared test oil is tested in an emulsified form (water: oil is 95:5 wt%), the variation range of the emulsified particle size of the rolling fluid before and after 4-ball milling is much lower than that of the original rolling oil, indicating that the use of the metalworking oil additive of the present invention helps to enhance the emulsification stability.
另外，採用軋延油1與本發明的實施例1於反覆式軋延機進行實際軋製鋼品以進行比較，兩測試油種均以乳化型態進行金屬加工（水：油為95：5 wt%）。請參照圖1a至圖1c，測試結果顯示，實施例1的使用可有效降低第七道次的軋延力。過往使用軋延油1無法軋製的現象明顯改善，第七道次之軋延力約可降低約300噸（200mpm定速段，在入、出口張力設定相同的前提下），軋製鋼板之軋延力、前滑率以及頭尾低速段變異幅度均有明顯降低的跡象（如圖1a所示）。另外，再比較軋延油1與實施例1在第七道次之不同軋速段的軋延力，相較於軋延油1，更可明顯得知實施例1的使用，可使軋延力降低約20至25%。In addition, rolling oil 1 and Example 1 of the present invention were used to roll steel products in a repetitive rolling mill for comparison. Both test oils were used in an emulsified form for metal processing (water: oil is 95:5 wt%). Please refer to Figures 1a to 1c. The test results show that the use of Example 1 can effectively reduce the rolling force of the seventh pass. The phenomenon that the rolling oil 1 could not be used for rolling in the past has been significantly improved. The rolling force of the seventh pass can be reduced by about 300 tons (200mpm constant speed section, under the premise that the inlet and outlet tensions are set the same), and the rolling force, forward slip rate and head and tail low-speed section variation range of the rolled steel plate all show signs of significant reduction (as shown in Figure 1a). In addition, by comparing the rolling forces of rolling oil 1 and Example 1 at different rolling speeds in the seventh pass, it can be clearly seen that the use of Example 1 can reduce the rolling force by about 20 to 25% compared with rolling oil 1.
此外，亦將使用軋延油1與本發明的實施例1的兩款油品所生產鋼捲進行X射線光電子能譜儀（XPS）分析，軋延油1試片有明顯之鐵、矽氧化訊號，占總鐵、矽量分別為12.4與6.7%（如圖1b所示）。此分析結果表明油膜在此軋製條件下已有部分遭受破壞（由於油品極壓性較薄弱的緣故），因而導致底材的氧化反應。In addition, steel coils produced using rolling oil 1 and the two oil products of Example 1 of the present invention were analyzed by X-ray photoelectron spectroscopy (XPS). The rolling oil 1 test piece had obvious iron and silicon oxidation signals, accounting for 12.4% and 6.7% of the total iron and silicon respectively (as shown in Figure 1b). This analysis result shows that the oil film has been partially destroyed under this rolling condition (due to the weak extreme pressure resistance of the oil product), resulting in oxidation reaction of the substrate.
此外，由軋延油1與本發明的實施例1之軋延液乳化態可知（如圖1c所示），本發明的實施例1於第七道次之軋延前、後乳化狀態變化並不明顯，顯見軋延液軋製過程中的穩定性。In addition, from the emulsified state of the rolling oil 1 and the rolling liquid of Example 1 of the present invention (as shown in FIG. 1c ), it can be seen that the emulsified state of Example 1 of the present invention does not change significantly before and after the seventh rolling, which shows the stability of the rolling liquid during the rolling process.
綜而言之，本發明所開發之同時提升油品極壓性與乳化性的金屬加工油品添加劑加入軋延油以中進行鋼品軋製時，油品可提供較佳之極壓特性，因此鋼捲無氧化現象（油膜完整），且完成鋼捲軋延後之乳化型態幾無改變，表示其熱穩定性較佳。In summary, when the metalworking oil additive developed by the present invention that simultaneously improves the extreme pressure properties and emulsification properties of the oil is added to the rolling oil for steel rolling, the oil can provide better extreme pressure properties, so that the steel coil has no oxidation phenomenon (the oil film is complete), and the emulsification form after the steel coil rolling and rolling is almost unchanged, indicating that its thermal stability is better.
雖然本發明已以較佳實施例揭露，然其並非用以限制本發明，任何熟習此項技藝之人士，在不脫離本發明之精神和範圍內，當可作各種更動與修飾，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。Although the present invention has been disclosed with preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
