Five functions of lubrication in stainless steel hot rolling
Zhengzhou stainless steel hot rolling is a stainless steel plate produced by the hot rolling process, and lubrication plays a key role in the hot rolling process
Zhengzhou stainless steel trapezoidal lead screw hot rolling is a stainless steel plate produced by hot rolling process, and lubrication plays a key role in the hot rolling process
1 improve the internal structure and performance of products:
the lubrication process accounted for 29% of the global market in 2012, which can improve the crystal structure of the rolled strip and improve its deep drawing performance
2 reduce the friction coefficient and reduce the rolling force:
due to the reduction of the friction coefficient, the rolling force is reduced (1) improve the production equipment, which can generally reduce the rolling force by 10%~25%, which reduces the rolling power and saves energy consumption
3 improve the surface quality after rolling:
the reduction of roll wear and black skin directly improves the surface quality after rolling
4 energy saving and consumption reduction:
after adopting process lubrication, the average power saving per ton of hot rolled steel is 3 degrees; Acid pickling solution reduced by 0.3~1.0kg; Metal consumption decreased by 1.0kg; The consumption of rolls can be reduced by 30% - 55%
5 reduce roll consumption and improve operation rate:
under hot rolling conditions, the working roll surface is oxidized due to long-term contact with cooling water, forming black skin, which is the main reason for abnormal roll wear. The use of special lubricants can effectively prevent the formation of black skin on the roll surface, prolong the service life of the roll, reduce the number of roll changes, and improve the operation rate of the mill
