Under the condition of compression, the cross-section of the
stainless steel plate will be reduced, the shape of the product will be changed, the length of the plate will be extended, and accompanied by widening. At this time, the surfaces of the rolled piece and the roll form relative sliding, forming friction, and accompanied by heat and deformation heat. During the rolling process, under the action of pressure in the deformation zone, the roll will form elastic deformation, and the stainless steel plate will produce plastic deformation. The rolling oil enters the deformation zone through the wedging effect of the stainless steel plate, and adheres to the stainless steel plate and the roll, so as to achieve the effect of lubrication and cooling.
The role of rolling oil in the cold rolling process of stainless steel plates is as follows.
One is to lubricate the roll and the stainless steel plate to reduce the external friction between the rolled metal and the roll, so as to reduce the wear of the roll, reduce the total pressure and energy consumption of rolling, increase the pass reduction rate, and reduce the rolling pass. , to increase the rolling speed.
The second is to fully cool the rolling deformation zone. With the help of the cooling effect of the rolling oil, the softening of the roll and the change of the roll shape can be avoided, so that the rolling process of the cold rolling of the stainless steel plate is more stable, which is conducive to strictly controlling the precision and shape of the stainless steel plate, and ensuring the precision and surface finish of the rolled stainless steel plate .
The third is to clean the rolling area and the surface of the stainless steel plate to prevent mechanical scratches on the surface of the roll and the stainless steel plate, and at the same time make the surface of the rolled stainless steel plate adhere to a layer of oil film, which is beneficial to achieve anti-rust effect in the turnover process of the subsequent process.
The performance of the rolling oil will directly affect the stability of the rolling process and the surface quality of the stainless steel plate. In order to ensure that the rolling process can be carried out stably, the rolling oil must meet the following performance requirements and have excellent lubricating performance; secondly, it has good cooling performance; it has excellent antirust performance, good detergency, good chemical stability and environmental protection healthy.
