Rolling oil composition used for cold rolling ordinary carbon steel plate under 1000mm and preparation method

The invention relates to a rolling oil composition and preparation method and belongs to the field of oil for metallurgical rolling mills, in particular to a rolling oil composition used for cold rolling an ordinary carbon steel plate under 1000mm and a preparation method. The rolling oil composition contains the following components in parts by weight: 300 parts of trimethylolpropane cocoate, 200 parts of palm oil, 20 parts of oleic diethanolamide, 40 parts of coconut oil diethanoamine condensate, 5 parts of engine oil (150SN), 30 parts of antirust agent (T746) and 5 parts of antioxidant (T501). The rolling oil composition can meet the lubrication requirement on rolling steel at high temperature to ensure the stability of a steel rolling process, and moreover, annealing detergence, rolling mill detergency and antirust property can be ensured under the no-clean condition.
