Metallurgical RollMetallurgical roll is mainly the centrifugally cast compound roll of high-level and good quality, including the large-sized centrifugally cast compound operating rolls for the mills for wide hot-rolled strips for rod and bar, rolled wire at high-speed and for hot rolled strip, and so an.Newly put out:The roll made from needle-like ductile iron is a special ductile iron roll of high-alloy. Comparing with the pearlite ductile iron of ordinary medium-and low-carbon, this material has higher comprehensive mechanical performances such as higher hardness, better wear resistance, stronger tenacity, etc. This kind of roll is mainly applied for the finishing stands of middle-sized rolling mills for bar and high-speed rolled wire.Improvement type of roll of high Ni-Cr-Mo unlimited chilled cast iron. The improvement type of roll of high Ni-Cr-Mo unlimited chilled cast iron gets improved wear resistance and roughness resistance through the controlling of the form of graphite and obtaining a partial dispersed MC carbide of high hardness. This indicates a higher operation performance. With the roll-body hardness of HSD75-85 and roll-neck tensile strength of Bb≥450Mpa,it is in the lead position in China.Specifications of large-sized metallurgical rollsDiameters of roll body: under ø1000mmLengths of roll body: under ø6000mmSpecifications of middle-and small-sized metallurgical rollsDiameters of roll body: ø250-ø600mmLengths of roll body: 500-1700mm
