Description:

The ingredients of alloy cast steel rolls adopt several microalloyed technologies to improve the metallurgic quality enable the rolls to meet different kinds of mills' needs. The features of alloy cast steel rolls are high hardness, high tensile strength,good bite and against heat crack. We use three methods to cast this kind of rolls: static, static cast slot and casement.
