Abstract

The invention relates to a rolling oil composition soluble in a degreasing agent and application of the composition mainly in order to solve the problems that existing rolling oil and the degreasing agent are poor in separation performance and the service life of the degreasing agent is affected. The composition is prepared from, by weight, 75-95 parts of component a which is highly refined mineral oil, 2-15 parts of component b selected from at least one of pentaerythritol oleate, isooctyl palmitate, isooctyl stearate, dibutyl phthalate or methyl palmitate, 1-8 parts of component c selected from at least one of inactive sulfurized olefin, tributyl phosphate, tricresyl phosphate, dibutyl phosphate and amine neutralized phosphate ester, 0.01-3 parts of component d selected from at least one of alkenyl succinic acid, butanedioic acid and alkyl succinic acid half-ester, 0.01-1.0 part of component e selected from at least one of propylene epoxide diamine polycondensate, ethylene oxide / propylene epoxide block polyether and polyether silicone oil comb-type copolymer and 0.1-5 parts of component f selected from at least one of N-phenylnaphthylamine, 1H-benzotriazole and alkyl diphenylamine.

Description

technical field [0001] The invention relates to a rolling oil composition compatible with a degreasing agent and its application. Background technique [0002] During the rolling process of the steel strip, impurities such as rolling oil, iron powder and dust will inevitably remain on the surface, so it must be cleaned before annealing to remove the oil on the surface of the strip steel, otherwise various residues on the surface of the strip steel will easily form during the annealing process. Carbonaceous stains pollute the atmosphere in the furnace and affect the decarburization efficiency. Degreasing and cleaning is an important link in the stainless steel cold rolling process, which can effectively remove the surface marks of the strip and improve product quality. [0003] The commonly used metal surface degreasing cleaning methods mainly include wiping, brushing, pickling, lye cleaning, organic solvent cleaning, ultrasonic cleaning, emulsification cleaning, etc. At pr...
