Pearlitic nodular cast iron rolls
Goods&specification（mm）:∮400—∮660
Goods net weight:950kg—4500kg
Product introduction:
Excellent pearlite, bainite and martensite matrix can be obtained by adding Ni and Mo alloy into ductile iron,Graphite is spherical, has good thermal conductivity and high tensile strength,by changing the structure into bainite, martensite and spicular nodular iron chemical composition and heat treatment process, the dense network of primary cementite can be obtained and the wear resistance can be improved.
Product feature:
The pearlite nodular cast iron rolls have good strength, high temperature and accident resistance,the hardness drop of working layer is small.
Product Application：
Mainly used in the continuous rolling mill of section steel, hot rolling mill of pipe, bar and wire mill, middle mill, pre - finishing mill and finishing mill.
