Work roll body length depends on the width of strip, sheet and band. Work rolls are usually used as drive rolls. In mill stands where ratio of body length to roll Ø ≥ 5:1, and a very thin alloy steel strip is rolled, and in multiroll machines backup rolls are used as drive rolls. .
Working Mill Rolls Forged mill rolls are the important spare parts in the cold rolling line. As forged mill rolls bear big rolling force andinstantaneous high temperature for welding line, slag inclusion and edge crack, forged mill rolls must have good strength, good wear resistance, heat impact strength, and good fracture toughness. We uses electroslag remelting process to keep forged raw ...
