Know about the reasonable rolling amount of tungsten carbide rollers and avoid excessive rolling is very important for steel rolling mills.
Micro-cracks in the groove during tungsten carbide roller rolling are unavoidable, and need to be repaired when reaching a certain depth (generally controlled at 0.2 mm). Excessive rolling causes the micro crack depth to expand faster, and the risk of crushing rolls increases and should be prevented. The recommended range of normal rolling capacity of tungsten carbide roller is as follows:
Stands of pre-finishing rolling mill ;( 3500-4000) tons
1-2 Stands of finishing rolling mill ;( 1800-2500) tons
3-4 Stands of finishing rolling mill ;( 1800-2500) tons
5-6 Stands of finishing rolling mill ;( 1500-2000) tons
7-8 Stands of finishing rolling mill ;( 1500-2000) tons
9-10 Stands of finishing rolling mill ;( 600-1200) tons
Stands for reducing and sizing mill;( 600-1200) tons
