Title:
DRAWING AND RUST REMOVAL PROCESS FOR STEEL WIRE
Document Type and Number:
WIPO Patent Application WO/2021/217950
Kind Code:
A1
Abstract:
A drawing and rust removal process for a steel wire, the production process thereof comprising the following steps: step 1, performing heat treatment on a wire and then pickling the wire; step 2, cleaning the pickled wire using high pressure; step 3, rinsing the wire in a rinsing tank; step 4, upon completion of cleaning, exposing the wire to the air to increase oxidation; step 5, making the wire enter a hydrochloric acid tank again and performing secondary pickling; and step 6, after the secondary pickling, performing the next process. The process facilitates removal of carbon deposition from surfaces of various kinds of medium and low carbon steel and chromium-molybdenum alloy steel after heat treatment has been performed thereon. Wire surface treatment is performed during the production process, so as to effectively improve the surface quality of formed wires without having to add other processes, thereby reducing costs.
