It's used for Long lifetime cemented carbide stud rolls for high pressure grinding roller
For breaking cement raw materials,clinker,Iron Ore,Copper,Diamond,Quartz.
The lifetime can reach from 8000-30000 hours according use different grade by different applications.
Production Process of Long lifetime cemented carbide stud rolls for high pressure grinding roller
To ensure the quality and the requirements of the drawings can be met before mass production
1st:, Start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2nd, Before mass production, do a trial pressing and sintering using mould,
3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.
Test process of Long lifetime cemented carbide stud rolls for high pressure grinding roller
1st,Mass production, press the raw materials to shape blanks,
Notes: all carbide stud pins blanks must be passed by semi finished inspection
2nd,Sinter blanks to finish (HIP) and finished products inspection,
Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.
3rd,Cleaning/tumbling to make the carbide stud pins clean and nice surface.
Packing of Long lifetime cemented carbide stud rolls for high pressure grinding roller
step 1, wrapped carbide stud pinsr in paper to avoid carbide stud pins be broken
step 2, put the carbide stud pins in inner small carton box
step 3, put the inner box into outer carton and fill the carton with foamed plastic
step 4, wrap the carton with packaging tape
