Medium alloy cold hardening centrifugal composite roll

The medium alloy cold hardening centrifugal composite roll and the medium alloy infinite cold hardening centrifugal composite roller have the structure of sorbite + bainite + martensite in the working layer of the medium alloy cold hardening centrifugal composite roll and the structure of the working layer containing only a small amount of graphite due to careful design of chemical composition and bold improvement of the technical control method of melting and pouring The hardness of the roller body is as high as 75-78hsd. Because of the above advantages, the wear resistance of the medium alloy cold hardening centrifugal composite roll is significantly improved (30-40% higher than the original), and the surface quality of the wire rod is also significantly improved. This kind of new material roller has been widely used in K1 stand of finishing mill of general line mill, which has won high praise from customers.
