INTRODUCE :
Alloy infinite chilled cast iron rolls are cast iron with fine intergranular graphite evenly distributed in the working layer of the roll body. The size, shape and distribution of graphite and carbides are controlled by the chilling effect and the content of alloying elements. The addition of alloying elements such as manganese, nickel, chromium and molybdenum transforms the matrix structure from pearlite and bainite to martensite. The presence of a small amount of fine graphite improves the roll's resistance to spalling, thermal cracking and wear.
Applications
1. Wire rod finishing.
2. Hot strip rolling and plate mill rolling of flat products.
3. Cold rolling of non-ferrous metal sheets.
