Steel wire machining method

Abstract

The invention belongs to the technical field of steel wire machining, and particularly relates to a steel wire machining method. The steel wire machining method comprises the following steps that rareearth materials and other elemental materials are mixed to obtain a rare earth mixture; scrap steel is cleaned and dried while the rare earth mixture is obtained; the cleaned and dried scrap steel isput into a rare earth smelting crushing system to be smelted together with the rare earth mixture, and thus alloy steel is formed; the alloy steel is produced into a stranded wire casting blank by adopting a horizontal continuous casting process of a composite electromagnetic stirring technology; and a wiredrawing die with a small-angle long die core is used for drawing the stranded wire castingblank, a drawn stranded wire is annealed, and thus machining of the steel wire is completed. According to the steel wire machining method, the rare earth materials and the scrap steel are mixed and smelted together through the rare earth smelting crushing system, thus the scrap steel can be refined, the shape of inclusions can be controlled, atmospheric corrosion resistance of the scrap steel is improved, toughness and plasticity are improved, the effects of desulfurization and neutralizing of low-melting-point harmful impurities on the scrap steel are achieved, and the comprehensive performance of the machined steel wire is improved advantageously.

Description

technical field [0001] The invention belongs to the technical field of steel wire processing, in particular to a steel wire processing method. Background technique [0002] Steel wire is one of the four major types of steel plates, tubes, shapes and wires, and is a reprocessed product made of hot-rolled wire rods through cold drawing. Steel wires are classified according to their uses: ordinary quality steel wires include steel wires for welding rods, nails, nets, packaging and printing industries, steel wires for cold upsetting rivets, screws, etc. Special steel wires for stranded wires, steel wires for textile industry include rough combs, healds 013, card clothing and needle wires, rope-making steel wires are specially used for the production of steel wire ropes and spokes, spring steel wires include springs and spring washers, pianos, tires, and cords Steel wires for transportation tapes, structural steel wires refer to steel wires for watch industry, ball bearings, and...

AI Technical Summary

Problems solved by technology

[0003] The main process of steel wire production includes raw material selection, iron scale removal, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc.; The surface treatment is not in place, so that the steel wire produced has poor processing performance, poor atmospheric corrosion resistance of the steel wire, and the toughness and plasticity of the steel wire are not very ideal.
