Mill Rolls

The mill rolls are mainly used for the rolling mill, which cause continuous plastic deformation of the metal. The roll is mainly composed of a roll body, a roll neck and a shaft head. The roll body is the middle part of the roll, which actually participates in the rolling of the metal with a smooth cylindrical or grooved surface.There are steel rolls, cast iron rolls, alloy rolls, ceramic rolls, etc, according to the roll material.Depending on the manufacturing method, the mill rolls have types of casting rolls, forging rolls, surfacing rolls, sleeve rolls, etc.Also mill rolls are classified into hot rolling rolls and cold rolling rolls, as per the steel.The properties and quality of a roll generally depend on its chemical composition and manufacturing method and can be evaluated by its microstructure, physical and mechanical properties.The mill roll features resistance to thermal cracking, high hardness, impact resistance, strict finish requirements, etc
