Bainitic ductile iron roll
Goods&specification（mm）:∮350—∮440
Goods net weight:600kg—1200kg
Product introduction:
Bainitic ductile iron roller is added with alloy elements such as nickel, manganese, chromium, molybdenum, etc. It is a matrix with needle-like structure (bainitic + a small amount of martensite). Through the optimization of alloy elements and special heat treatment, the purpose of optimizing the structure and performance of the roller can be achieved.
Product feature:
The impact toughness, elongation and other indexes of the roll are higher than those of the pearlite ductile iron roll, the toughness is better, and the wear resistance is also improved obviously. It can be produced by static casting or centrifugal casting, which can significantly prolong the service life of rollers and effectively reduce the production cost of rolling mills.
Product Application：
Small section steel continuous rolling, bar rolling, narrow strip mill stand, high-speed wire prefinishing.
