Cemented Carbide Roll / Tungsten

Cemented Carbide Roll / Tungsten
Cemented carbide roller composition, performance
Cemented carbide roller ingredients with different working conditions due to the roll, even in the same finishing mill, a roll component of the type of rack type. High-speed wire rod mill roll mainly cobalt as a binder carbide roll. Minority continuous casting and rolling mill due to poor water quality using the Co-Ni-Cr cemented carbide roller as a binder, the cost is also lower.
Cemented carbide roller has a high hardness, and its hardness value with temperature change is very small, the hardness value of 700 ° C when the HSS 4 times; Also elastic modulus, compressive strength, flexural strength, thermal conductivity higher than tool steel more than doubled. All of these performances are guaranteed cemented carbide roller is better than tool steel roller abrasion resistance and deformation resistance in the working process, thus ensuring a constant finish rolling the roller-shaped groove and size, which guaranteed the surface of the wire quality and dimensional accuracy, is essential. Due to the high thermal conductivity of the cemented carbide roller, so the cooling effect is good, so that the surface of the roll is in a high temperature short time, thereby rolls harmful impurities with the cooling water temperature reaction time is shorter. Therefore, the cemented carbide roller is more resistant to corrosion than tool steel roller resistance to thermal fatigue.
3. Cemented carbide roller development prospect
The cemented carbide roller has been used in various areas of metal plastic processing. From non-ferrous metals to steel, cold-rolled foil from hot-rolled wire, pipe, steel, etc. Used cemented carbide roller. China is capable of producing dozens of varieties from φ 8 ~ φ 300mm specifications cemented carbide roller. With wire finishing high-speed (maximum speed up to 130 m / s), the people are exporting methods to improve the strength and hardness of the cemented carbide roller. Which is added a small amount, TaC, NbC and Ni, Cr, Mo, and other elements in the cemented carbide roller; And by hot isostatic pressing, vacuum sintering a low pressure hot isostatic pressing, heat treatment and other means to take better quality roll system.
Cemented carbide roller rings (also known as tungsten carbide roll rings), superior performance, quality and stability, high precision machining, good wear resistance and high impact resistance. The cemented carbide roller is a roll made of tungsten carbide and cobalt material by powder metallurgy method.
