Production process of cemented carbide insert
1, TC-- tungsten carbide become the liquid phase around 1300
degree,and cobalt powder as a binder phase to fill the gap between
the TC
2, others' elements such as nickel, titanium, it act as to
reinforced alloys for corrosion-resistant
3, milling and drying.
4, pressing, through automatical pressing machine to press powder
to shape,nd we check the appearances and the sizes of samples with micrometer, projectors etc. to ensure that the
requirements of the drawings can be met before batch production
5, sintering, through vacuum sintering to improve the performance
of the HPGR carbide insert
