Product Description

High Chromium Rolls

This type of rolls is High Chromium Centrifugal Duplex Rolls, produced from high alloy material, whose microstructure is bainite and chrome carbides, the core of the rolls is filled with spheroidal graphite cast iron.the carbide morphology in the outer microstructure is no longer M3C type, but becomes M7C3 type with high microhardness, good wear resistance and chrysanthemum distribution. After high temperature heat treatment, it has good comprehensive properties at high temperature. The microhardness of matrix and carbide is high and the wear resistance is good.

Now there are a lot of steel plant use High Cr Cast Rolls in intermediate stand to replace SG rolls, the work life of Hi Cr iron rolls is much higer than SG rolls, so the period of changing rolls will be long, and the production efficiency will increase, so that the cost will be decreased for per ton steel.
