tungsten carbide cold rolls

 

  • high dimensional precision, good surface finish and improved strength for cold rolling wire rod
  • made from virgin raw materials, with high hardness and wear resistance
  • the service life of cemented carbide roll rings is 20-50 times longer than that of tool steel
  • non-destructive ultrasonic flaw detection, without sand hole, pore, cracks and inclusions
  • a complete range of size for carbide wire rolls, rolls is sintered by HIP-sinter furnace

 
Tungsten carbide cold rolls are mainly used to produce smooth wire or ribbed wire for wire industry. Our rolls include oval reducing(RO),round reducing(RT),forming(FO)profiling(PR),sizing(CA).Other types are also available as per your requirements. The rolling volume reaches 800-1500 tons one time, which is 20-50times higher than that of ordinary tool steel. It can be used repeatedly by grinding, which greatly reduces the cost and significantly improves the benefit and efficiency.

How to make tungsten carbide rolls

powder milling → formula according to grade→ wet grinding → mixing → crushing → drying → sieving → adding forming agent → redrying → sieving to obtain a mixture → granulating → pressing → forming → Sintering →preforms→rough machining by flat grinding→non-destructive ultrasonic flaw detection →finishing machining by flat grinding→internal grinding →external grinding→chamfering→notching machining→laser marking→inspection →packing → Storage
