Description

Technical Field

[0001] The present invention relates to a steel wire preparation technology and equipment for use thereof, and in particular to an online film-type steel wire drawing process. Background Art

[0002] How to improve the quality of the drawn product is a major challenge in steel wire preparation. When preparing steel wire, if the drawing speed is too fast, the surface is easily scratched. If the drawing speed is too slow, the production efficiency will be affected and the production cost will be high.

[0012] 5) The middle temperature raising module heats the steel wire to no less than 250°C before forming the secondary film;

[0013] 6) The steel wire heated before the secondary coating enters the coating agent tank B. The coating agent B in the coating agent tank B has a temperature of 75-80°C. The secondary coating is formed on the surface through contact with the high-temperature steel wire;

[0014] 7) The hot air high temperature drying module provides a temperature of 200-220°C for drying to complete the epithelial film process before drawing;
