DETAILED CARBIDE TOOLS MAKING PROCESS

1. Raw Material Preparation: Tungsten trioxide (WO3) and carbon black are blended in precise proportions. 2. Blending and Grinding: The mixture is blended to ensure a uniform composition. 3. Reduction Reaction: The mixture is heated to high temperatures in a hydrogen atmosphere, causing carbon to react with tungsten trioxide and form tungsten carbide. 4. Carburization: Tungsten monocarbide (WC) is further carburized to enhance its properties. 5. Cooling and Crushing: The carbide is rapidly cooled and crushed into smaller particles. 6. Forming and Sintering: The crushed carbide particles are mixed with a binder and shaped into green compacts, which are then sintered. 7. Sintering: The green compacts are heated in a controlled atmosphere, causing the binder to melt and bond the tungsten carbide grains together. 8. Finishing Operations: Carbide parts may undergo additional processes such as grinding, polishing, coating, or heat treatments.
