Abstract

A hot-pressed oil composition containing oily-dispersing clay antifriction anti-slip agent has excellent dispersing ability, abrasion resistance and lubricity. The composition consists of 0.1-15wt% sulfur-contained extreme pressure agent from alkyl polysulfide, mineral oil sulfide and thiopoly alcohol ester, 0.1-20wt% phosphor-contained anti-scuff agent from organic phosphate, phosphonate ester, phosphate ester, acid amine salt organic phosphate, amine salt phosphate ester, phosphoamidster, dialkyl phosphateodithioate, dimercaptothioliazole phosphorodithioate and acid phosphate imidazoline salt and 0.01-1wt% oil-soluble clay anti-scuff lubricant of organic modified clay and C4-C24 hydroxy-acid compound or C13-C64 hydroxy-acid contained condensate. It has excellent dispersibility, abrasion resistance and lubricity.

Description

technical field [0001] The invention relates to a hot rolling oil composition. Background technique [0002] The use of hot-rolling oil is a new technology in the field of modern steel rolling. Early hot-rolling did not use oil but was lubricated with water. Later, hot-rolling oil was directly used to lubricate the rolls. Its ingredients include mineral oil, animal and vegetable oils, and synthetic fatty acids. Lubricating oil, causing great pollution. The lubricity of hot rolling has been greatly developed in the past ten years. At present, many large-scale hot rolling mills use the lubrication technology of water and oil co-spraying instead of pure oil lubrication. During the rolling process, a very small amount of hot rolling oil and A large amount of water (more than 99.5%) is mixed, forced to emulsify, sprayed onto the surface of the work roll, and the emulsion is brought into the deformation zone through the rotation of the roll, which not only effectively cools the r...
