We all know that the main component of cemented carbide is carbide micron-sized powder of high-hardness refractory metal. Therefore, it is very solid. Many people are asking whether the cemented carbide used in the cemented carbide ball teeth is a metal? How did cemented carbide come about? The following small series will explain to you the manufacturing method of cemented carbide ball tooth cemented carbide.
1. The manufacturing method of cemented carbide is as follows: firstly, the bonding alloy is made by high-energy ball milling; then the ingredients are proportioned according to the specified weight of cemented carbide components, and the ball is reinforced, and then the cemented carbide mixture obtained by ball milling is processed. Vacuum sintered forming.
2. The main materials of cemented carbide ball teeth are: tungsten carbide (WC), titanium carbide TC. Cemented carbides mainly include: tungsten-cobalt (WC+Co) cemented carbide (YG), tungsten-titanium-cobalt (WC+TiC+Co) cemented carbide (YT), tungsten-tantalum-cobalt (WC+TaC+Co) Cemented carbide (YA), tungsten titanium tantalum cobalt (WC+TiC+TaC+Co)) cemented carbide (YW).
3. An ultra-fine cemented carbide ball tooth cemented carbide and its manufacturing method. The alloy is a composite alloy composed of the main component WC hard phase, Co-Al as a binder metal phase and a rare earth metal element phase; the alloy The composition and weight content are as follows: Co-Al bonding metal phase: Al13~20%, Co80~87%; composite alloy: Co-AL10~15%, Re1~3%, WC82~89%. The manufacturing method is as follows: firstly, the bonding alloy Co-Al is prepared by high-energy ball milling; then, the ingredients are proportioned according to the specified weight of the cemented carbide components, and the ball-milling is strengthened, and then the cemented carbide mixture prepared by the ball-milling is vacuumized. Sintering, the sintering temperature is 1360°C, and the holding time is 20 minutes. ****** Produced ultra-fine cemented carbide.
