Study of High Chromium Cast Iron Roller
The production process for high-chromium cast iron roller was introduced.By choosing chemical composition of Cr20 material reasonably and developing casting process and heat treatment process via combining solidification characteristics of high-chromium cast iron,the targets which are the roller hardness 53 HRC in the cast state and 61 HRC after heat treatment can be achieved,making sure the roller non-destructive testing qualified as well,and the casting quality achieve the advanced level of domestic equivalent products.
