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.
Nozzles
Wire guides
Traditionally, the original guide rolls and straighteners initially included in new machines for deforming, forming and welding wire for the manufacture of steel structures and electro-welded wire mesh are made of steel. These components suffer a great deal of wear inherent in the process and are therefore ideally suited for replacement with replacement parts made of carbide.
Driven by their customers, welded steel mesh manufacturers and machine builders are increasingly demanding that spare parts be made from hard metal, a material that offers optimum resistance to wear. Components made from carbide have a longer service life than original steel components. Maintenance time and downtime are reduced and the quality of the end product is improved, as dimensions are maintained more uniformly.
Cold rolled product features:
Because there is no annealing treatment, its hardness is very high (HRB greater than 90), mechanical processing performance is very poor, can only be a simple directional less than 90 degrees of bending process (perpendicular to the direction of coiling). Simply put, cold rolled, is rolled on the basis of hot rolled coil, generally speaking, is hot rolled → pickling → cold rolled such a process.
Cold rolled is processed from hot rolled sheet at room temperature, although in the process because of rolling will also make the steel plate warming, but nevertheless still called cold rolled. Cold rolled by the hot rolled through continuous cold deformation from the cold rolled, the mechanical properties are relatively poor, the hardness is too high, it must be annealed to restore its mechanical properties, no annealed rolled hard rolled called. Rolled hard roll is generally used to do without bending, stretching products, 1.0 thickness rolled hard luck on both sides or four side bending
Application of cold rolled wear parts:
-Steel manufacturing
-Steel tube manufacturing
-Titanium wire manufacturing
-Cold rolling and hot rolling technology, etc.
