Problems solved by technology

[0005] The problem to be solved by the present invention is that the lubricating performance of conventional rolling oil is not enough to meet the lubrication requirements of multi-roll tandem rolling mills, and it is easy to cause scratches on the plate surface during the cold rolling process, vibration of the rolling mill, excessive rolling force or failure to meet the working conditions. Provide a new high-lubricating rolling oil composition

The composition is prepared from 40-90 parts of highly refined mineral oil, 10-30 parts of carbon dodecanol tetradecyl alcohol, isotridecyl alcohol, n-octanol, pentaerythritol oleate, trimethylolpropane trioleate, diisooctyl phthalate, 2-ethylhexyl palmitate, isooctyl stearate, methyl palmitate or butyl stearate, 1-5 parts of ZDTP, octadecyl zinc dithiophosphate, sulfurized olefin, sulfide aliphatic acid ester, sulfurized animal oil, alkyl sulfide or sulfur phosphorus molybdenum, 0.5-5 parts of amine thiophosphate, isooctyl acidic phosphate octadecylamine, tricresyl phosphate, tributyl phosphate, dibutyl phosphate and carbon-12 to carbon-14 acid phosphate compound ester, 0.1-5 parts of 2,6-butylated hydroxytoluene, N-phenyl naphthylamine, thioether phenol or alkyl diphenylamine and 0.01-2 parts of 1H-benzotriazole, thiadiazole derivative and benzotriazole.

Description

technical field [0001] The invention relates to a high-lubrication rolling oil composition and its application. Background technique [0002] In the cold rolling process of stainless steel plates, there are multi-roll single-stand reversing mill technology and multi-stand continuous rolling mill technology. When performing process lubrication, there are pure oil-type rolling oil and emulsified rolling oil. The process lubrication of most multi-stand continuous rolling mills uses emulsified rolling oil. Some continuous rolling processes have relatively high requirements on the surface of the rolled stainless steel plate, so pure oil-type rolling oil is used. This continuous rolling process has higher requirements on the lubricating properties of pure oil-type rolling oil. [0003] If the pure oil-type rolling oil used in this continuous rolling process has poor lubricating performance, it is easy to cause scratches on the plate surface during the cold rolling process, vibrat...
