Work Roll

Forged steel work roll performs as a tool to transform materials under normal room temperature, therefore , it is the most wear and tear spare parts during the rolling process . With 2%Cr, 3%Cr, 5%Cr material series , we have greatly improved our products both in terms of quality and diversification . Currently , our product is widely used in a variety of applications , such as anti hydrogen-attack roll, ultra-deep hardened roll, anti-roll mark roll, anti-roll accident roll and the high wear resistance roll and so on .

Due to the demanding surface soundness of those products, these kinds of flaws will definitely brought a negative effect on the strip quality. We haveupgraded their rolls' anti-press-in and anti-scratches capabilities by adjusting the rolls' alloy composition and heat treatment techniques. The barrel's hardness can reach over HRC64. Granted as National Patent, this tech can satisfy the requirement of high-performance cold rolled products such as sheets for automobile and high-class household electrical appliances.

In rolling some steel sheets with higher strength, phenomenon as "slippery" will often occur resulting from excessively fast decreasing of toughness. As a result, the quality of sheet will degrade while roll change frequency will increase. It not only affects the output but also raises the roll's consumption.
