Application of Tungsten Carbide Rollers in High-Speed Wire Production
Tungsten carbide rollers are widely used in high-wire mills. In high-speed wire rolling mill, the rolling force, rolling moment and wear of the ring on different stands are different, so different grades of tungsten carbide must be used accordingly.

From the structural form of tungsten carbide rollers, there are 2 kinds of whole tungsten carbide rollers and composite tungsten carbide rollers. The whole tungsten carbide rollers has been widely used in prefinishing and finishing stands of high-speed wire rolling mill. Composite tungsten carbide rollers are made of tungsten carbide and other materials, and can be divided into tungsten carbide composite rollers and whole tungsten carbide composite rolls. The tungsten carbide composite rollers is installed on the roller shaft by mechanical connection and is applied to small rolling mill, high-line rolling mill, steel pipe three-roll mill etc..the whole tungsten carbide rollers and composite rollers are directly cast into the roller shaft to form a whole, applied to rolling mills with very large rolling loads.
Tungsten carbide rollers are widely used in high-wire mills. In high-speed wire rolling mill, the rolling force, rolling moment and wear of the ring on different stands are different, so different grades of tungsten carbide must be used accordingly. In general, the front stand has a large rolling load, the tungsten carbide rollers is required to have good toughness and strength, should choose the grade with higher binder content. The rear stand is over the steel long time, and the tungsten carbide rollers is required to have better wear resistance, should choose the grade with lower binder content, especially the finished product and the finished product front stand rollers has a direct impact on the surface quality and tolerance of finished wire products, compared with the previous stand, it is more often needed to change the roll, change the groove, usually the number of replacement is often 2-4 times of the previous stand, its wear resistance often plays a decisive role in improving the efficiency of the whole mill.
