The elements of nickel,chrome and molybdenum etc.are added in the ductile cast iron,after through special heat treatment,the pearlite ductile cast iron roll can be obtained.Such king of roll possesses fine strength,hi-temperature-resistant and anti-accident performances,including its small drop height of hardness in work layer.
