Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel wire processing, in particular to a device for removing residual coatings on steel wires. Background Art
[0002] In the steel cord industry, various coatings are used during drawing. These coatings are classified into two types: metallic and non-metallic. Metallic coatings are generally difficult to remove, and among non-metallic coatings, phosphate coatings are also difficult to remove due to a chemical reaction with the steel wire. Borax coatings, another commonly used coating, adhere to the surface of the steel wire and are relatively easy to remove. Traditionally, borax coatings have been used as a lubricant carrier for dry drawing of steel cord.
[0003] The coating requires a lubricant during drawing. Typically, soap powder is used as a lubricant for steel wire drawing. Borax absorbs the soap powder and acts as a drawing coating. During drawing, heat is released, softening the soap powder. Some of the soap powder remains attached to the wire, while some is charred. This residual coating—the borax and soap powder mixture remaining on the wire surface after drawing—needs to be removed. Because the residual borax and soap powder mixture adheres to the wire, it can be carried and dispersed throughout the production site during transportation and subsequent heat treatment processes, resulting in excessive dust.
[0004] During heat treatment production, traditional steel cord manufacturers use a conditioning tank. This process primarily removes uneven residual coatings from the steel wire surface and then absorbs a certain amount of coating into the heat treatment process. However, the amount of residual coating carried in is greater than the amount removed. To maintain a stable concentration in the conditioning tank, water must be added. When excessive water is added, the conditioning tank's liquid overflows, requiring waste treatment, significantly increasing costs. Utility Model Content
