Description of tungsten carbide 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 |

Advantages of cemented carbide studs
1. continuous production of buttons over 18 years
2. total production quantity of buttons up to 800 tons
3. widely exported to Europe,America,Austrialia,Brazil,India,Russia
etc
4. round edges,protect the studs being damaged during
production,transpotation,installment and using
5. Hip sintering ensure good compactness and high toughness for the
products
6. grease used on surface of the products to avoid oxidization
7. hemishperical top,protect the studs from being destroyed by
stress concentration
Model available of cemented carbide studs
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 cemented carbide studs
1, Soon after the order is confirmed, tungsten carbide studs 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 tungsten carbide studs 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 tungsten carbide studs blanks must be passed by semi finished inspection,
