Rolling oil composition used for cold rolling of common carbon steel plate with size less than 650mm and preparation method of rolling oil composition

Abstract

The invention relates to a rolling oil composition and a preparation method thereof, belongs to the field of oil products used for metallurgical rolling mills, and particularly relates to a rolling oil composition used for cold rolling of a common carbon steel plate with the size less than 650mm and a preparation method of the rolling oil composition. The rolling oil composition comprises the following components in parts by weight: 250 parts of trimethylolpropane cocoate, 20 parts of oleic diethanolamide, 40 parts of coconut oil diethanolamine condensate, 50 parts of vulcanized lard oil, 305 parts of engine oil (150SN), 30 parts of an antirust agent (T746) and 5 parts of an antioxidant (T501). The rolling oil composition provided by the invention can meet the requirements of lubricating rolled steel under a high temperature so as to guarantee the stability of a steel rolling process; annealing cleanliness, and cleanliness and antirust property of the rolling mills can be guaranteed in a washing-free condition.

Description

technical field [0001] The invention relates to a rolling oil composition and a preparation method, which belong to the field of oil products for metallurgical rolling mills, and in particular to a rolling oil composition and a preparation method for cold-rolling common carbon steel plates below 650 mm Background technique [0002] Carbon 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 broken belt, steel plate deviation, and even rolling mill vibration occur. Even if the concentration is reduced, the problem cannot be solved fundamentally, but it leads to rust prevention Poor other issues.

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 broken strip, steel plate deviation, and even rolling mill vibration occur. Even if the concentration is reduced, the problem cannot be solved fundamentally, but it leads to rust prevention Poor and other issues

[0003] In addition, the rolling oil of traditional steel rolling mills mainly uses animal and vegetable oils as oily agents, which have a high saponification value, and the low volatility of animal and vegetable oils affects the cleanliness of the rolled plate surface after annealing, and is prone to solidification in winter , it is inconvenient to use, and the splashed emulsion will separate and solidify 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
