Dec 08, 2013· Fig 1 Typical rolls for cold rolling. Besides the chemical composition, physical and mechanical properties (micro structure, hardness, YS, UTS etc.) of the materials of the rolls, other properties which are important, are young''s modulus, poisson''s ratio, co efficient of thermal expansion, heat conductivity and co efficient of heat transmission.
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 ...
