  • Tungsten Carbide Ring Rolls for Cold Rolling

    What is cold rolling?
    Cold rolling is the use of hot rolled steel coils as raw material, after pickling to remove the oxide skin for cold continuous rolling, the finished product is rolled hard coil, due to continuous cold deformation caused by cold hardening of the rolled hard coil strength, hardness, toughness and plasticity indexes, so the stamping performance will deteriorate, can only be used for simple deformation of the parts. Rolled hard coil can be used as raw materials for hot-dip galvanising plant, because hot-dip galvanising units are set up with annealing line. Rolled hard coil weight is generally 6 ~ 13.5 tonnes, steel coil at room temperature, the hot-rolled pickling coil for continuous rolling.

    Typical products of carbide tools for cold rolling:
    Ring rolls
    Rodillos arrastradores
    Feeding rolls
    Integral straightening dies, or inlaid tungsten carbide straightening and guide pillar dies.
    Wire guides
