Centrifugal and Static Casting Steel Base Adamite Roll
Its micro-structure is composed of matrix and carbide with carbon content of 1.3-2.3%,depending on content of alloy and heat treatment process. The matrix consists of pearlite and bainite, with the addition of Cr, Mo and Ni for higher stability of carbide, enhanced high-temperature resistance and strengthened matrix, the roll has the special merits of being small in drop of hardness, highly wear and high-temperature resistant, and high in load bearing capacity feature etc.
