Description

Technical Field

[0001] This invention relates to the field of metal rolling technology, and in particular to a wire rolling mill with rust prevention function. Background Technology

[0002] A wire rod mill is an industrial device used to process metal billets into wire rods through a continuous rolling process. Its core function is to gradually transform large metal billets into fine, uniform wire rods through multiple passes of extrusion and extension by the rolling mill. It is widely used in construction, power, automotive manufacturing, and hardware processing. The wire rod mill contains pairs of cylindrical rolls with grooves on their surfaces. By rotating and extruding the metal billet, its cross-section is reduced and its length extended. Wire rod mills are divided into hot rolling and cold rolling. Cold rolling is performed at room temperature, thereby improving the surface finish and strength of the wire rod, and is used for precision wire rods. After rolling, the wire rod is directly wound up by a winding device.

[0003] Cold-rolled wire rods require anti-corrosion treatment. When metal wire rods are exposed to air, water, or corrosive environments, their surfaces are prone to reacting with oxygen, moisture, or chemicals, leading to oxidation and rust. Applying an anti-rust coating can form a physical or chemical barrier, fundamentally blocking the conditions for rust to occur, thereby increasing the storage time of the wire rods.

[0004] Existing wire rod mills do not readily coat the wire rod surface with anti-rust materials after rolling, making it easy for the wire rod to rust due to external environmental factors during storage, thus affecting the quality and storage time of the wire rod. Summary of the Invention
