Steel Rolling Mill Machine: Hot Rolling Roll
At present, there is a trend of using bucket steel rolls to replace forged steel rolls. The roll of the 6VH billet continuous rolling mill in the Baosteel blooming mill is made of forged semi-steel and forged cast iron with 1.7% ~ 2.4% C, which has good wear resistance and poor hot crack resistance.
