Adamite Rolls


Texture profile

The carbon content is usually in the range of 1.2-1.7%, component contains Cr, Ni, Mo and other alloying elements, roll with a special heat treatment process, compared with the conventional alloy steel roll has good wear resistance, thermal crack resistance, roll using layer hardness drop is small.

Main application

  • Wok roll for hot strip mill, plate mill, vertical roller mill Steckel.
  • Work rolls for 4Hi roughing hot strip mill.
  • Section mill roll, bloom roll.
  • Section mill roll edge roll, S roll.
