FCAW flux cored wire drawing machinery

Capstan structure for flux cored wire drawing machine  Material is ZG45 steel casting blank body, after quenching and tempering treatment, HB250. Dig 5mm depth on the working surface of capstan, then melt the tungsten, cobalt carbide, overlay welding. Then rough lathing, precision lathing, grinding and polishing, surface roughness can reach to 0.08μm, hardening layer height 300mm, depth more than 3mm, HRC 58-62. All the surface of capstan is processed by lathe, non-contact and operation surface's roughness is 6.3μm, capstan inner wall sprays zinc, can effectively reduce the formation of cooling water scale. Capstan spindle hole against axis beating up tolerance is ±0.03μm, capstan dynamic balance level is G6.3. All the surface of capstan is processed by lathe, non-contact and operation surface's roughness is 6.3μm, capstan inner wall sprays zinc, can effectively reduce the formation of cooling water scale.
