Tungsten carbide round rods are generally prepared by powder metallurgy, which generally includes the following steps:
- Preparation of tungsten powder: crush and grind tungsten raw materials to make tungsten powder.
- Preparation of tungsten carbide powder: Mix tungsten powder and carbon black in a certain proportion and react at a certain temperature and pressure to make tungsten carbide powder.
- Press the embryo: Pour the tungsten carbide powder into the steel mold and press the embryo.
- High-temperature sintering: Put the blank into a sintering furnace and sinter it at high temperature, so that the tungsten carbide powder particles melt and combine with each other to form a dense tungsten carbide round rod.
- Cooling and treatment: After the tungsten carbide round rod is cooled to room temperature, necessary mechanical processing (such as cutting, grinding, etc.) and heat treatment (such as quenching, tempering, etc.) are performed to obtain the required shape and properties.
It should be noted that the preparation process of tungsten carbide round rods is very complicated, and the raw materials, equipment and process conditions involved need to be precisely controlled to ensure that the quality and performance of the product meet the requirements.
