Spring Wire Produce Process
- Wire rod
Raw material for steel wire products is supplied by steel mill. Steel mills make wire rod by hot rolling process from billet.
- Surface treatment
Descaling wire rod removes rust and scales on the surface of wire. Surface coating wire rod facilitates drawing.
- First Drawing
Descaled and surface coated wire rod is brought to 1st drawing machine to draw to required diameter and to give mechanical properties suitable for application.
Heat treatment to transform wire into required microstructure and to facilitate drawing.
- Intermediate Drawing
Intermediate Drawing after 1st drawing.
