Tungsten carbide strips are mainly made by mixing tungsten carbide and cobalt powder through powder milling, ball milling, pressing and sintering by metallurgical methods; cutting or grinding if necessary, final inspection, packing, then delivery. Middle inspection is done after each process to make sure only the qualified products can be moved to next production process.
The content of WC and Co in cemented carbide strips for different purposes is not the same, and the application range is extremely wide.
To ensure the quality, HRA tester, TRS tester, Metallographic microscope, coercive force tester, cobalt magnetic tester are used. Drop test is another good way to make sure there is no material flaw in the whole long strip. Size inspection as per order is also a necessary inspection process.
1. Used to make wear-resistant tools. Such as woodworking baldes, plastic crushing baldes, etc.
2. Cut to small pieces to make high-temperature resistant parts, wear-resistant parts, and anti-shielding parts.
3. Used to make Grinding support plate in grinding machine, corrosion-resistant parts in the chemical industry.
4. Different other applications.
