On the basis of original alloy composition of normal ICDP,the hardness of carbide is increasing by adjusting the other elements and the graphite is refining by modification treatment of molten iron. Besides, the hardness fall of radial work layer is smaller. ICDP ROLLS

At present the enhanced rolls are generally used as work rolls for finishing stands of 4-high hot strip mill, work rolls for roughing stands/finishing stands of hot strip mill and 4- high wide strip of reversing mill, work rolls for 4-high cold strip mill, work rolls/back-up rolls for tempering stands of 4- high hot strip mill and steckle mill. The rolling tonnage per millimeter is increased a lot compared to ordinary rolls due to good hardness fall and structural properties.
