Problems solved by technology

In the cold-rolled emulsified oil rolling process of the strip steel in the prior art, rolling putty is very likely to remain on the strip steel surface, which affects the surface finish of the strip steel and seriously affects the surface quality of the strip steel after galvanizing. The use concentration is high, the use period is short, and the oil slick in the rolling liquid pool is serious, which increases the production cost of the enterprise and the recognized labor intensity

Abstract

The invention relates to a strip steel cold rolling emulsified oil and a preparation method thereof.The strip steel cold rolling emulsified oil is prepared from 10%-40% of a component A, 15%-45% of a component B, 5%-20% of a component C, 3%-10% of a component D, 2%-8% of a component E, 2%-8% of a component F, 1.8%-7% of a component G and 1.5%-6% of other auxiliaries H.The cold rolling emulsified oil is appropriate in viscosity, good in volatility and moderate in saponification value; the emulsion particle size is moderate after the cold rolling emulsified oil is dissolved in water, so that rolled strip steel is good in surface finish and free of residues, which plays a key role in improving the galvanization quality of strip steel in a subsequent process; the rolling liquid is long in service life, low in cost and capable of prolonging the service life of rollers and reducing product cost; besides, the preparation method is simple and easy to apply and popularize on a large scale, so that good economic benefits and social benefits are brought.

Description

technical field [0001] The invention relates to the technical field of strip steel cold rolling lubrication and rust prevention, in particular to a borate-containing strip steel cold rolling emulsified oil and a preparation method thereof. Background technique [0002] In the prior art, the preparation method of emulsified oil for cold rolling of strip steel is usually: take mineral oil as the main raw material, heat it to a certain temperature, add emulsifier, oily agent, anti-wear agent, antioxidant, anti-oxidant, etc. Rust agent and other additives. In the cold-rolled emulsified oil rolling process of the strip steel in the prior art, rolling putty is very likely to remain on the strip steel surface, which affects the surface finish of the strip steel and seriously affects the surface quality of the strip steel after galvanizing. The use concentration is high, the service life is short, and the oil slick in the rolling liquid pool is serious, which increases the produc...
