Various materials are selected to produce roll rings according to different requirements, such as pearlite, bainite, semi-steel, GT semi-steel, graphite steel, high chromium iron, high chromium steel, high-speed steel, etc.
The roll ring is assembled on the high-strength forged steel roll shaft through an interference fit, which ensures the wear resistance of the working layer and has sufficient strength. At the same time, the roll shaft can be reused many times, saving energy and cost.
