Roll produced by forging steel ingot. Forging can forge the metallurgical defects such as porosity and shrinkage cavity in the ingot, break the coarse casting structure, and obtain high-quality rolls with dense structure and uniform composition. Forged steel rolls have better strength and toughness, surface hardness uniformity and fatigue resistance than similar cast rolls. (Table 1) in order to meet the specific requirements of different rolling mills and rolling conditions, different alloy elements can be added to the roll steel to improve the roll performance. A certain amount of carbon and alloy elements have the following different effects on the structure and properties of forged steel rolls: carbon can increase the hardness and strength of rolls, reduce plasticity and improve wear resistance; Manganese can increase hardenability and strength; Silicon deoxidizes and improves strength; Chromium can increase hardenability, strength and wear resistance; Molybdenum can increase hardenability, strength and thermal hardness; Vanadium can control the grain size of steel and increase the strength. See Table 2 for the main chemical composition of common forged steel hot rolls and backup rolls.
