Description:

The technology of Bainite nodular cast iron rolls is improved from the method of conventional casting rolls, and it is alloyed but not heat treated, so the rolls’ wear resistance, tensile strength, anti-accident ability are superior to those conventional rolls. The adoption of Bainite nodular cast iron rolls can increase the producing efficiency, and gain the economic benefits.
