When the
stainless steel plate is under pressure, the cross-section will be reduced, the shape will be changed, and the length will be extended. At this time, the surface of the rolled piece and the roll will form relative sliding, causing friction, accompanied by frictional heat and deformation. heat formation. 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 form plastic deformation.
The stainless steel rolling oil enters the deformation zone through the wedging effect of the strip, and will adhere to the stainless steel plate and roll, so as to achieve the effect of lubrication and cooling.
There are three main functions of stainless steel plate rolling oil in the cold rolling process. One is to lubricate the roll and the stainless steel plate, reduce the external friction between the rolled stainless steel plate and the roll, thereby reducing the wear of the roll and reducing the total rolling. Pressure and energy consumption, increase the pass reduction rate, reduce the rolling pass, and speed up the rolling speed.
The second is to fully cool the rolling deformation zone. With the help of the cooling effect of the stainless steel plate rolling oil, the softening of the roll and the change of the roll shape can be avoided, so that the rolling process of the stainless steel plate is more stable, which is conducive to strictly controlling the precision and shape of the product, and ensuring the precision and surface finish of the rolled stainless steel plate.
The third point 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. Anti-rust effect.
The performance of stainless steel rolling oil will directly affect the stability of cold rolling stainless steel rolling process and the surface quality of stainless steel. In order to ensure that the rolling process can be carried out stably, the stainless steel plate rolling oil must meet the following performance requirements, namely, it must have good lubricating performance, good cooling performance, excellent anti-rust performance, in addition, it must be easy to clean, chemical properties Stable and safe and environmentally friendly.
