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.
