- Production process and finishing of cemented carbide:
- Metal W\C Powder： High purity tungsten powder is used as raw material.
- Preparative mixture：The rolling ball mill makesthe powder ingredients homogenize.The surface area of the powder is increased and the particle surface is increased.Can increase and promote sintering.
- Slurry spray drying：The preparation of mixtures is used in a closed environment.High purity nitrogen protection, effective reduction of preparation.In the process, the mixture may increase oxygen, and can.Ensure the purity of material and prevent material.The dirty.
- Compression moulding： Using the method of static pressure mechanism, effective du.Absolute suppression of defects, high density.and even.
- Degumming and pre-burning semi-inspection processing
- Vacuum low pressure sintering：thermostatic sintering Maximum sintering pressure can reach 100 kg.The residual hole clearance in the alloy is minimized.In addition, it is highly compactand good.Degree, high strength alloy blank.Advanced control,The temperature system can effectively reduce the hard alloy plate.The possibility of quality fluctuation occurs.
