Production process for bright titanium wire

Abstract

The invention aims at providing a production process for a bright titanium wire, which can be used for overcoming the defects in a traditional process. The production process comprises the process flows of cogging and rolling of titanium ingots, wire drawing, descaling and obtaining finished products, wherein the step of descaling is finished by the step that a titanium wire is introduced from a small port and drawn out of an expansion port by using a scalping die provided with a horn port in the middle. According to the improved production process for the titanium wire, a work procedure of coping a grinding wheel and an acid-alkali washing work procedure are omitted; titanium chips generated by wire drawing and scaling can be recycled; no pollution from acid and alkali is generated; and the drawn titanium wire has a bright and attractive surface, enhanced strength and hardness, favorable elasticity and more perfect service effect. In addition, the production process disclosed by the invention has a favorable economic benefit; in the known production process, about 15 percent of loss is generated and cannot be recycled; and in the improved process disclosed by the invention, about 1.3 percent of loss is generated and can be recycled. The improved production process has no pollution to the environment and a better social benefit.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal processing, in particular to a preparation process of titanium wire. Background technique [0002] Existing titanium wires are generally treated with an acid-base corrosion process, so the surface of the titanium wires is gray, the surface is not bright enough, and the sensory perception is poor. At the same time, because titanium has good corrosion resistance and high strength, it is often used as a hanger for hanging electroplating parts in the electroplating industry. The titanium wires currently commonly used as hangers are all prepared by acid-base washing process, and have an oxide layer on the surface. The oxide layer falls off during use and will pollute the electroplating solution. [0003] The production process of titanium existing titanium wire hanger is: titanium ingot --- blanking --- rolling --- drawing --- grinding --- drawing --- acid-base cleaning --- finished product. ...

AI Technical Summary

Problems solved by technology

The existing process is complex and long. The grinding process uses a grinding wheel to rub the surface of the titanium wire. The loss is invisible and cannot be recycled. The acid-base washing process makes the titanium wire inevitably cause annealing, which reduces the hardness and strength of the titanium wire. The elasticity is not good and There is pollution, the use effect is not good
