The main processes of galvanized iron wire production include raw material selection, removing oxidized iron sheet, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc. Selection of raw material: Removal of oxidized sheet refers to the removal of oxidized sheet from the surface of the rod or middle line blank. The purpose is to prevent the oxidized sheet from damaging the surface of the mold and galvanized iron wire during drawing, to prepare a good surface condition for subsequent coating or coating treatment, and to reduce the friction during drawing to reduce the drawing force. There are chemical and mechanical methods to remove iron oxide, see chemical dephosphorization of rod and mechanical dephosphorization of rod.
Galvanized iron wire production process mainly includes the following parts: galvanized iron wire drawing, mold repair technology, heat treatment normalizing, quenching technology, pickling phosphating technology, galvanized iron wire production technology, galvanized iron wire processing technology, wooden wheel production technology, galvanized iron wire packaging technology, etc. Among them, the most critical is galvanized wire drawing, heat treatment, galvanized wire rope production of these three links, these three links are often the most easy to affect the quality of galvanized wire.
The operation essentials of galvanized iron wire technology is based on the actual operation experience of the production of each process and the relevant national standards, master the galvanized iron wire rope production process and skilled application, can effectively ensure the quality of products, energy saving and consumption reduction, increase the economic benefits of enterprises.
