Rolling oil composition for cold rolling of low alloy steel plate and preparation method

Abstract

The invention relates to a rolling oil composition and a preparation method, belongs to the field of oil for metallurgy and rolling mills, and particularly relates to a rolling oil composition for cold rolling of a low alloy steel plate and a preparation method, wherein the rolling oil composition for a low alloy steel plate rolling mill comprises the following components in parts by weight: 300 parts of trimethylolpropane coconut acid ester; 300 parts of coconut oil; 20 parts of oleic diethanolamide; 40 parts of coconut oil diethanoamine condensate; 100 parts of sulfurized lard oil; 30 parts of antirust agent (T746); 5 parts of antioxidant (T501); 5 parts of engine oil (150SN). The rolling oil composition is applied to the rolling mill, can meet the requirement on rolled steel lubrication at high temperature and guarantee the stability of a steel rolling process, and also can guarantee annealing detergence, rolling mill detergence and anti-rust property under the no-clean condition.

Description

technical field [0001] The invention relates to a rolling oil composition and a preparation method, belonging to the field of oil products for metallurgical rolling mills, in particular to a rolling oil composition and a preparation method for cold-rolling low-alloy steel plates. Background technique [0002] Steel plate processing is an important process in metal processing. The rolling oil of the traditional steel rolling mill is easy to cause over-lubrication on the rolled steel plate, and problems such as plate breakage, steel plate deviation, and even rolling mill vibration occur. Poor other issues. [0003] In addition, the rolling oil of the traditional steel rolling mill has a high saponification value, and the low volatility of animal and vegetable oils affects the cleanliness of the rolled plate surface after annealing, and it is prone to solidification in winter, which is inconvenient to use and emulsified by splashing The oil precipitates and solidifies around ...

AI Technical Summary

Problems solved by technology

The rolling oil of the traditional steel rolling mill is easy to cause over-lubrication on the rolled steel plate, and problems such as plate breakage, steel plate deviation, and even rolling mill vibration occur. Poor and other issues

[0003] In addition, the rolling oil of the traditional steel rolling mill has a high saponification value, and the characteristics of low volatility of animal and vegetable oils affect the cleanliness of the rolled plate surface after annealing, and it is easy to solidify in winter, which is inconvenient to use and emulsified by splashing The liquid precipitates and solidifies around the rolling mill, which affects the cleanliness of the rolling mill. If the concentration is reduced, it will not solve the problem, but will lead to other problems such as poor anti-rust performance
