Introduction:
Adding relatively more Chromium alloy elements in its outer layer brings a special carbide structure. Compared with normal roll, it has higher wear resistance, hardness, strength, and campaign rolling tonnage. The core part adopts alloy spheroidal graphite(SGP) to ensure the roll's integral strength.
