The manufacturing process parameters of cemented carbide can be optimized and adjusted through the following methods:
- Optimize the selection of alloy materials: According to specific application requirements, rationally select alloying elements of different components, and determine the optimal material formula according to different component ratios and heating processes.
- Powder preparation process control: Optimize the powder preparation process, such as using water atomization, gas atomization or plasma methods to control the particle size and distribution of the powder to avoid the occurrence of coarse carbide grains and cobalt pools.
- Mixing process control: A reasonable mixing process can fully mix the raw materials and control the particle size composition of the mixture to meet the needs of different products.
- Molding process control: Choose a suitable molding process, such as press molding, injection molding, etc., and control the pressure and temperature during the molding process to obtain cemented carbide products with good density.
- Sintering process control: Optimize sintering process parameters, such as sintering temperature, time and atmosphere, etc., to obtain cemented carbide products with excellent properties.
- Quality inspection and control: During the manufacturing process, strict quality inspection and control, such as chemical composition analysis, physical property testing, etc., are carried out to ensure the quality and reliability of cemented carbide products.
In short, the optimization and adjustment of cemented carbide manufacturing process parameters requires comprehensive consideration of various process links such as alloy material selection, powder preparation, mixing, molding and sintering. Through continuous testing and improvement, the density and uniformity of the alloy can be improved to avoid unevenness. Defects such as wrapping phases and pores appear. At the same time, quality inspection and control are also important links in ensuring the quality of cemented carbide products.
