Why are tungsten carbide stud damaged?

Although tungsten carbide stud have the advantages of wear resistance and high hardness, their shear resistance is slightly weaker. Damage can also occur during use, such as breakage or accelerated wear. During the production and operation of the grinding roller stud, the studs are subjected to severe high-stress abrasive wear, shear force damage and long-term fatigue damage. During the operation, the studs will break, peel off and serious wear problems, which will affect the rolling. Hourly output and service life of the machine. Here is a summary of the common causes of damage to tungsten-cobalt carbide studs

1. Applicability and quality issues of cement grinding studs. In the selection of cemented carbide grades, the type must be selected according to the abrasiveness of the material in actual use conditions, and the most suitable stud grades with performance indicators such as hardness, bending strength, and impact toughness must be selected.

2. Abrasive wear. With the repeated operation of the roller press, the studs are formed and damaged in a cycle of the protective layer of the material pad, which causes the abrasive wear of the studs.

3. Shear damage. Although cemented carbide studs have ultra-high wear resistance, they have poor shear resistance. Under the impact of large materials, the phenomenon of carbide studs breaking, falling off angles, and accelerated wear will inevitably occur. Therefore, control The size of the material is critical.

The above are the common causes and solutions for the damage of tungsten-cobalt carbide studs, hoping to help you reduce the probability of damage to the tungsten carbide studs. Improve the service life of carbide studs. Please choose Zhuzhou Jinxin for high-quality cemented carbide column top.
