Abstract

The invention provides high speed tandem cold rolling silicon steel strip rolling oil and a preparation method thereof and relates to the technical filed of lubricants. The method comprises the following steps: successively adding pentaerythritol oleic acid ester, butyl stearate trimethylol propane monooleate, EAK, di-n-butyl phosphite, 2,6-di-teutyrt-bl-p-cresol, petroleum sodium sulfonate, TX-4 and TX-7 into a reaction kettle; stirring with a revolving speed of 80 to 110 rpm and heating to 80 to 85 DEG C; stirring under a heat preservation condition for 30 to 35 minutes; then cooling to 70 DEG C; further adding alkyl phenol polyoxyethylene ether and re-stirring under the heat preservation condition for 20 to 25 minutes; cooling to room temperature to obtain brown-yellow uniform and transparent silicon steel strip rolling oil. The rolling oil has the benefits of high safety, efficiency and environmental friendliness, can effectively reduce the rolling force, the delivery thickness and the friction coefficient in the rolling process, apparently improve the surface quality of the rolled steel strip, and the surface smoothness of the rolled steel strip is higher, the corrosion prevention cycle is longer, and the annealing detergence is better.

Description

technical field [0001] The invention relates to the technical field of lubricants, which are used for process lubrication in the high-speed continuous cold rolling process of silicon steel strips, in particular to a high-speed continuous cold rolling silicon steel strip rolling oil component content and a preparation method thereof. Background technique [0002] With the improvement of the equipment capacity of modern cold strip rolling mills, the deformation and rolling force of rolling silicon steel strips by continuous rolling mills are no longer the main problems, but the lubrication technology to ensure the surface quality of silicon steel strips after rolling has become a technical difficulty. Due to the large deformation resistance of the silicon steel strip during the cold rolling deformation process, and the hardness of the silicon steel itself is high. Therefore, in the high-speed continuous cold rolling production process of traditional strip rolling oil, due to t...
