The Advantages of Tungsten Carbide Rolls for Rolling Mills

Tungsten carbide itself has a very high hardness, its hardness is much higher than traditional roll materials such as cast iron and steel, so that tungsten carbide rolls in the rolling process can effectively resist friction and impact, reduce the wear of the roll surface, and then have a longer service life and stable performance. For example, in the high-speed wire rod mill, the use of tungsten carbide rolls can be in a long period of high-speed rolling process, to maintain the dimensional accuracy of the roll grooves and surface finish, so as to ensure the surface quality of the wire rod.

Under the working environment of high pressure and high temperature, tungsten carbide roller can maintain the surface finish and flatness for a long time, and are less prone to wear, fatigue and cracks, which is the ideal choice for high-intensity and high-load working conditions. For example, when rolling stainless steel and other hard materials, cemented carbide rolls wear significantly lower than ordinary rolls, greatly reducing the frequency of roll replacement and improving production efficiency.

Higher thermal conductivity so that the roll surface at high temperatures in a shorter period of time, and cooling water in the harmful impurities in the high-temperature reaction time is also shortened accordingly, so compared with the tool steel rolls, cemented carbide rolls are more corrosion-resistant, resistant to hot and cold fatigue, in some harsh working environment, such as poor water quality continuous casting rolling mill, the use of tungsten carbide rolls can effectively avoid corrosion caused by the roll ring damage, reduce equipment maintenance costs.
