Production process editing broadcast
The main process of steel wire production includes raw material selection, iron scale removal, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc.
For raw material selection, see steel wire raw materials.
Removal of iron oxide scale refers to the removal of iron oxide scale on the surface of wire rod or intermediate wire billet, the purpose is to prevent the oxide scale from damaging the surface of the mold and steel wire during drawing, to prepare good surface conditions for subsequent coating or plating treatment and to reduce friction during drawing Reduce pullout force. There are two types of methods for removing iron scale, chemical method and mechanical method, see chemical descaling of wire rod and mechanical descaling of wire rod.
