Applications
Cast tungsten carbide can be used as the oil drilling & exploring drill matrix by the way of melt-penetration. It can also bead-welded at the location at the locations where wear resistance on the unit by oxygen-acetylene welding or by electrical welding, spray welding, brazing welding and infiltrating welding. At those locations where the working temperature is not high and impact is low, this material can firmly adhere onto the surface of the wear parts with help of epoxy resins or inorganic binder.
Cast tungsten carbide is widely used in mining industry, petroleum industry, metallurgy industry, construction machinery, agriculture machinery and steel industry. For example, for making and other melt-infiltration products in oil drilling & exploring industry. It can also be used for surface reinforcement of cutting drills, scraper drills , cone rock bits, and tools in machinery industry.
The application of cast tungsten carbide can greatly improve heat-resistance and impact-resistance of the piece, and prolong the work piece performance life, thus, lighting the reparation labor, lowering production cost and raising productivity.
