Tungsten cemented carbide roller

various OEM

Tungsten cemented carbide rollers can be divided into solid carbide rolls and composite hard alloy rolls according to the structure. Solid carbide rolls have been widely used in pre-finishing and finishing stands for high-speed wire rod mills (including fixed reduction racks, pinch roll stands).

The composite tungsten cemented carbide roll is made of cemented carbide and other materials and can be divided into hard alloy composite roll ring and solid carbide composite roll. The cemented carbide composite roll ring is mounted on the roller shaft; for the solid carbide composite roll, cemented carbide roll ring is directly cast into the roll shaft to form an entirety, which is applied to the rolling mill with the large rolling load.


Features

The tungsten cemented carbide rollers have high hardness, and its hardness changes very little with temperature changes. The hardness at 700 °C is 4 times that of high-speed steel; and the elastic modulus, compressive strength, flexural strength, and thermal conductivity are also over 1 time higher than tool steel.

Since the thermal conductivity of the tungsten cemented carbide roll is high, the heat dissipation effect is good, and the time at which the surface of the roll is at a high temperature is short so that the high-temperature reaction time between the roll and the harmful impurities in the cooling water is short. Therefore, the tungsten cemented carbide roll is more resistant to corrosion and cold and hot fatigue than the tool steel roll.

Application:

Tungsten Carbide rollers are widely used in metal forming, especially in hot rolling industry mainly for intermediate and last finishing stands to ensuring superior surface finish and dimensional stability of processed metal products. Rolls are also commonly used for wire flattening, de-scaling and straightening applications.
 
Tungsten carbide roller used on the stretch reducing mill for bars, thread steel bars and common wire with the durability 10 to 20 times higher compared to common steel roller. The surface quality and the steel bar size accuracy are greatly improved. The cemented carbide roller reduces effectively the production cost and improves the quality. Roller for Profile Wire Rolling, Flat Wire Rolling, Construction Wire Rolling, Plain Wire Rolling and Welding Wire Rolling, Wire Straightening, Wire Guiding etc.
