The present invention mainly solves the above-mentioned technical problem existing for prior art, provides a kind of rolling oil composition for cold rolling below 650mm common carbon steel board and preparation method.This rolling oil composition can meet the stability requirement of steel rolling lubrication being ensured under high temperature to rolling process, and can ensure annealing cleanness under No clean condition, milling train detergency and rust-preventing characteristic.
In order to solve the problems of the technologies described above, according to an aspect of the present invention, provide a kind of rolling oil composition for cold rolling below 650mm common carbon steel board, include the component of following parts by weight:
Optimize, above-mentioned a kind of rolling oil composition for cold rolling below 650mm common carbon steel board, described machine oil is 150SN base oil.
Optimize, above-mentioned a kind of rolling oil composition for cold rolling below 650mm common carbon steel board, described rust-preventive agent is T746 rust-preventive agent.
Optimize, above-mentioned a kind of rolling oil composition for cold rolling below 650mm common carbon steel board, described antioxidant is T501 antioxidant.
In order to solve the problem, according to a further aspect in the invention, propose a kind of method preparing the above-mentioned rolling oil composition for straight carbon steel slab milling train, comprising:
Step 1, adds machine oil, is warming up to 60-70 DEG C, adds oxidation inhibitor, is stirred to dissolving;
Step 2, cools to 60 DEG C, and add TriMethylolPropane(TMP) cocounut oil acid esters, sulfurized lard stirs;
Step 3, adds rust-preventive agent at 50 DEG C, stirs 30 minutes, then add oleic acid diethyl amide, coconut acid diethanolamide stirs 30 minutes, obtains the present composition.
Therefore, tool of the present invention has the following advantages: (1) lubricity is better, has rational saponification value, can meet the requirement of common carbon steel board milling train steel rolling to lubrication; (2) independently synthesize extreme pressure additive, ensure the lubrication under high-temperature and high-pressure conditions; (3) independently synthesizing synthetic ester, and adopt complete synthesis Recipe, without causing annealing unclean vegetable and animals oils, ensure that the detergency in lubrication and the rear plate face of annealing, and zero pour is lower; (4) allocate efficient extraordinary rust-preventive agent into, ensure the rustless property of steel; (5) distinctive emulsifier ratio technology, controls size and the stability of emulsion granularity, more can ensure the stability of rolling process.
