The material contains a certain amount of Cr, Ni, Mo and other alloying elements, static casting production is tempered sorbite + part carbides, and there is a part of the free state of spheroidal graphite.
It is abrasion resistance, excellent resistance to thermal cracking. Hardness Control in 40-55 HS range, with a high temperature overall performance, it can ensure stability under high temperature micro structure and stable performance with higher life of the material.
BD ductile iron alloy roll, for multi-chassis BD universal beam mill rolls, especially the type of steel used for rolling rail, can greatly improve the life of rolling mill roll, and increase mill productivity.
