Product Description

Unit price will be decided by engineering drawing.

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.

The resulting roll has excellent performance for rolling ferrous and non-ferrous metals, and can withstand heavy loads and high-speed rolling operations. The outer layer of the roll also has good heat resistance and can resist thermal shocks, ensuring stable rolling operation and longer service life. Overall, adding chromium alloy elements to the roll's outer layer enhances its wear resistance, hardness, and strength, while the use of alloy spheroidal graphite in the core
