High Density Long Worklife Grade RX650 HPGR Tungsten Cemented Carbide Studs / Rolling Machine Studs
Recommended grades of rolling machine studs
grade above are exclusive grade we developed for rolling machine,good wear resistance and high strength are suitable for metal smashing with high working efficiency.lifetime of carbide stud is over 8000-10000 hrs.
Grades | Density(g/cm3) | Hardness(HRA) | T.R.S≥N/mm2 |
RX-11 | 14.4 | 87 | 2700 |
RX-15 | 14 | 87 | 3000 |
RX650 | 13.8 | 88.2 | 3100 |
RX20 | 13.5 | 85.5 | 3200 |
If rolling machine uses cemented carbide stud,it gets high density,high strength and good impacting property,lifetime of cemented carbide stud is over 10 times more than surfacing material
Production process of rolling machine studs
mainly raw material
1, tungsten carbide powder
2, cobalt powder
TC-tungsten carbide
TC become the liquid phase around 1300 degree, and the cobalt powder acts as a binder phase to fill the gap between the TC and etc.
Others' trace elements such as titanium.and Nickel, it acts as to reinforced alloys for corrosion-resistant
Milling Time
Fine&Sub-Micron 72-96 hrs, 3-4 days
Medium : 24-48hrs, 2 days
Utra-Micron: more than 96 hours, 4 days
dry 24 hours, 1 day
Pressing
Sintering
SM02/SM03/SM06/SM07/SM09
Vacuum sintering 1420 degree
after sintering, the hardness and performance improve 20% around, to longer the items'life
Grinding, usually we according to cutomers' requirement and drawing to grind and polish
