There is fine intergranular graphite in the working layer of the alloy infinite chilled hard roll. The size, shape, and distribution of graphite and carbide can be controlled by quenching and alloy content, and the matrix structure can be pearlite, bainite, or martensite due to the addition of alloying elements such as manganese, chromium, nickel, and molybdenum. In addition, there is a small amount of fine graphite, which not only improves the spalling resistance, hot cracking resistance and wear resistance of the roll, but also the hardness drop of the working layer of the roll body is very small. It is used in bars, wire rods, small section steel rolling mills, middle rolling and finishing rolling stands.
