Mill roll

• Roller is an important consumable part of rolling mill and has a long service life.

• The roll surface has high hardness and precision, good wear resistance and heat resistance.

• Refined raw materials, strict production process, can be processed a variety of roller shapes.

• Used as work roll, finishing roll for strip steel, wire rod, section steel and non-ferrous metal rolling.

Features

As important consumable parts of rolling mill, the functions for bearing the rolling force, and the influences resulted from wearing and temperature variation. The rolls are categorized as work roll, intermediate roll, backup rolls, etc. The fabrication processes of the roll include forging, rough machining, conditioning, non-destructive inspection, finishing machining, quenching and grinding, thus the rolls have the characteristics of high surface hardness, excellent wear and heat resistance, and high accuracy; the crown surface profile of the rolls is machined by precision roll grinder. The roll quenching layer is quite deep, and can be ground repeatedly to a certain extent. The rolls can be used as working roll and rough, medium, finishing rolls of strip steel, wire rod, section steel and non-ferrous metal rolling.
