In rolling sheets for automobiles and household electrical appliances, the dent imperfection brought by the foreign objects on the roll's surface will most probably be passed on to the strip surface to cause color difference and pit in the rolled product. Due to the demanding surface soundness of those products, these kinds of flaws will definitely brought a negative effect on the strip quality.
Changzhou Roll has upgraded 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.
