Graphite Steel Rolls have good resistance to fire crack and prevent oxidized scales from adhering, which is widely used on blooming and roughing stand
Product Description
The characteristics of Graphite Steel Rolls are similar to those of Adamite Rolls. The main character is that it contains a small amount of fine graphite in its microstructure, which will increase its resistance to fire crack and prevent oxidized scales from adhering. This material are widely used on blooming and roughing stand.
