graphite Steel
rolls

The carbon content and matrix of graphite steel rolls are similar to those of adamite rolls. Its 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.

Application

  • Intermediate and finishing stands of heavy section mills
  • Finishing stands of rails
  • Pilger mills
  • Vertical Edgers of hot strip mills
