The specific steps of the cemented carbide round bar extrusion forming process mainly include:
- Preparation of mixed slurry: Mix cemented carbide raw material powder, binder, solvent, etc. together to prepare a plastic mixed slurry.
- Vacuum drying: vacuum dry the mixed slurry to remove moisture and volatile components and improve the quality and stability of the mixed slurry.
- Screening: Screen the vacuum-dried mixed slurry to separate materials of different particle sizes for the subsequent pressing process.
- Pressing: The screened materials are pressed into the preliminary shape of cemented carbide round rods.
- Sintering: The pressed carbide round rods are sintered at high temperature to make the alloy composition more stable and to increase the hardness and strength.
- Processing: Process the sintered carbide round bars, such as turning, drilling, etc., to obtain the required shape and size.
These steps are the basic process of cemented carbide round bar extrusion forming process. The specific operations may vary depending on different manufacturers and products of different specifications. In the actual production process, adjustments and optimizations need to be made according to specific conditions.
