Abstract

The invention provides an emulsion-type steel plate cold-rolling lubricating oil composition. The emulsion-type steel plate cold-rolling lubricating oil composition comprises, by weight, 85-95.5% of a component A, 0.5-5.0% of a nonionic compound emulsifier, 1.0-10.0% of a lubrication additive and 0.5-2.0% of a high / low-temperature anti-oxidant, and the component A comprises animal and plant oil, synthetic ester and mineral oil. The emulsion-type steel plate cold-rolling lubricating oil composition has the advantages of excellent lubricity, rolling mill cleanability, stable emulsibility and good impurity oil resistance. The emulsion-type steel plate cold-rolling lubricating oil composition is suitable for multi-rack high-speed cold rolling or single-rack reciprocating cold rolling, can be used for rolling of a cold-rolled sheet, a tinned thin sheet and an electrotechnical silicon steel plate and can be used for preparation of an emulsion for cycle use.

Description

technical field [0001] The invention relates to an emulsified steel plate cold rolling lubricating oil composition. Background technique [0002] Steel plate rolling, as a non-loss forming processing method, is widely used in the iron and steel machinery industry. As a high-tech cold rolling process, it is highly valued. According to the cooling lubricating oil supply method used in rolling, it can be divided into two types: direct injection or one-time oil supply and circulating oil supply. With the improvement of environmental protection requirements and the conservation of resources and energy, most of them now use circulating oil supply, that is, the lubricating oil is mixed with water and recycled, and the impurities such as iron powder produced are removed. At this time, more stringent requirements are put forward for the recycled lubricating oil. In addition to good lubricity, emulsification stability, annealing and rust resistance, it is also required to have stable...
