Tungsten carbide rings,which is powder metallurgy technology was invented in 1909, was born with the development of metal processing industry. Since 1918, Germany launched after the cemented carbide drawing die, inspired the study of carbide, all kinds of USES roll appeared one after another. But the application of cemented carbide roll is after 1960. Morgan, 1964 (Morgen) the birth of the first high-speed twist wire mill, the speed of wire rod finishing at that time Increased four times. Because of the finishing mill group is working under high speed, high stress, the wear resistance of cast iron roller, tool steel roller, groove life is short,tungsten carbide rings of repair loading and unloading is very frequent, affect the efficiency of the mill,has not adapt to the request of the finishing production, replaced by combined carbide roll. More than two hundred sets of Morgan rolling mill in the world, cemented carbide roll consumption hundreds of tons.
Tungsten carbide rings have high hardness, and the hardness value is rather small, along with the change of temperature of 700 ℃ when the hardness value is four times that of high speed steel; And modulus of elasticity, compressive strength,bending strength, thermal conductivity were also higher than that of tool steel more than 1 times. Due to their high thermal conductivity of carbide roll, so the cooling effect is good,make the roll surface at high temperature time is shorter, thus make the roll cooling water with harmful impurity in the high temperature reaction time is shorter. Therefore,tungsten carbide rings are more than tool steel roller corrosion resistance, resistance to cold and hot fatigue.

tungsten carbide rings quality control

  • all raw material are tested in terms of density, hardness and T.R.S before use.
  • There are strict inspection on process and final products.
  • every batch of product can be traced.
