Juncheng Corporation was found in 2011 at Changde city, China. We are commited to making and supplying rolls for plain steel and long steel both hot and cold rolling mills 12 years. Steel and iron rolls production capacity: 100,000 Tons/year;
Rolls max size: 8m long, 1.6 m dia. ,barrel length 2.6m and max weight 55 tons .
Centrifugal and static alloy indefinite chilled cast iron rolls ( ICDP)
Grade properties: The outer layer has fairly high metallurgical properties. The amount of graphite in the working layer of the roll body has almost no change in the depth direction because the hardness difference of the working layer is very small. The hardness of the roll mainly depends on the type of matrix structure, namely sorbite, bainite or martensite.
