Production points of spring steel wire

The main processes of spring steel wire production include raw material selection, scale removal, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc.
Removal of scale refers to the removal of oxide scale on the surface of wire rod or intermediate wire blank. The purpose is to prevent the oxide scale from damaging the surface of die and spring steel wire during drawing, prepare good surface conditions for subsequent coating or coating treatment, reduce friction during drawing and reduce drawing force. There are two kinds of methods to remove scale, chemical method and mechanical method. See wire rod chemical descaling and wire rod mechanical descaling.
