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

SPP Industry Ltd.

In the 1990s, SPP Industry Ltd was one of the first manufacturers to establish CNC machining in China. The company has now established five major machine parks in China, with significant achievements in the areas of 5-axis machining, precision grinding & honing, gear machining, large parts machining, custom tungsten carbide and new material development respectively.
