The manufacturing process of tungsten steel round rods with holes mainly includes the following steps:
- Powder making: Mix tungsten steel powder and cobalt powder according to a certain proportion, and blow the mixed powder into the container through high-pressure air.
- Press molding: Pour the mixed powder into the mold, press it through a hydraulic press, and then demould.
- Sintering: Put the formed body into a sintering furnace for high-temperature sintering to eliminate stress and improve strength and hardness.
- Grinding: Grind the sintered green body to obtain tungsten steel holed round rods of the required size and shape.
- Post-processing: Perform heat treatment, chromium plating and other post-processing to improve the surface hardness and anti-corrosion performance of tungsten steel round rods with holes.
The following points also need to be noted during the manufacturing process of tungsten steel round rods with holes:
- The ingredients must be accurate: the proportion of tungsten steel powder and cobalt powder must be prepared as required to obtain the best performance.
- The forming pressure must be appropriate: The forming pressure must be controlled during the pressing process to prevent the green body from deforming or cracking.
- The sintering temperature and time must be appropriate: The temperature and time must be controlled during the sintering process to prevent cracks or deformation of the green body.
- The grinding process must be precise: Appropriate grinding tools and grinding parameters must be selected during grinding process to obtain precise size and shape.
- Post-processing must be sufficient: Post-processing processes such as heat treatment and chromium plating must be fully carried out to ensure that the surface hardness and anti-corrosion performance of the tungsten steel holed round rod meet the requirements.
