There are two forming methods for the production of cemented carbide round rod: One is extrusion molding, which is a suitable way to make long rods. It can be truncated to any length desired by the user during extrusion. However, the overall length cannot exceed 350mm. The other is molding, which is a suitable way to produce short bar. As the name implies, it is to press the carbide powder into shape with a mold.
Carbide ball has high hardness, high wear resistance, good chemical stability and thermal stability, mainly used in the petrochemical industry valve ball, special bearing ball, testing instrument measuring head ball, electric tools and die ball, widely used in precision machinery, aerospace, military defense, petrochemical and other fields.If you want to purchase or customize tungsten steel balls such products, choose a company that controls the quality strictly.
The studed roller needs to rely on the high wear resistance of the cemented carbide studs to break the material, but the high hardness of the cemented carbide studs itself produces great stress deformation on the base material of the roller sleeve. Today, most roll press manufacturers use a special adhesive method to connect the carbide stud to the mounting hole in the base material of the roll cover. The bonding strength of cemented carbide stud and hole directly determines whether the cemented carbide nail can be fixed stably on the roll surface. Therefore, in order to ensure that the cemented carbide stud does not fall off, it is necessary to improve the strength of the hole wall of the carbide studs, select a high strength adhesive, and install the cemented carbide studs.
