Carbide Buttons / Hpgr Tungsten Carbide Cement Grinding Studs From China
- Description
1. Flat top, protect the HPGR carbide studs from being destroyed by stress concentration.
2. Round edges, protect the HPGR carbide studs being damaged during production, transportation, installment and using.
3. HIP sintering ensure good compactness and high toughness for the products.
4. Special technology to eliminate the surface stress after surface grinding, and increase the surface hardness at the same time.
5. Grease used on surface of the products to avoid oxidization.
Grades below 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 cemented carbide pins over 8000-10000 hrs.
Dimensions can be done by client's drawing.
| Grades | D(g/cm3) | HRA | ≥ 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 |
Remarks:
Dimension refers to sketch.
Customize for client’s requirements is available.
Fully angular differs from different models.
Unit: mm 
If rolling machine uses carbide stud pin, it gets high density,high strength and good impacting property. Lifetime of carbide stud pin is over 10 times more than surfacing material.
1, Soon after the order is confirmed, carbide stud pin products will start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2, Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of carbide stud pin samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production
3, Bulk production ,press the raw materials to shape blanks,and all carbide stud pin blanks must be passed by semi finished inspection.
4, Then sinter blanks to finish (HIP) and finished products inspection, we have 10 sets of vacuum sintering furnace and 2 sets of HIP in the factory ensure the best quality and production capacity.
5, 1). cleaning/tumbling is to make the carbide stud pin look more beautiful.
2).The ccarbide stud pin can be ground according to customers’ order tolerance requirement
step 1, wrapped carbide stud pin in paper to avoid carbide stud pin to broke
step 2, put the carbide stud pin in inner small carton box
step 3, put the inner box into outter carton and fill the carton with foamed plastic
step 4, wrap the carton with packaging tape
step 5, you can choose any delivery way such as DHL,TNT,UPS ect.
