Abstract

The invention discloses a pure titanium wire for a spectacle frame and a manufacturing method thereof. 0 to 0.20 weight percent of O element and 0 to 0.26 weight percent of Fe element are added in the pure titanium cast ingot smelting process. The amount of Fe and O elements needed to be added during reinforcement is obtained according to the strength theta 0 of original spongy titanium, and the adding amount of Fe and TiO2 in the pure titanium material smelting process is determined further. Through forging, rolling, drawing and annealing processes, the strength controllable pure titanium wire is prepared and meets requirements on titanium wire properties of different parts of the spectacle frame. In the smelting process for preparing the pure titanium material, accurate amount of Fe element and O element are added, and chemical composition content in the pure titanium wire is controlled, so that the strength of the pure titanium wire is accurately controlled, the strength deviation of TA2 pure titanium wires produced in different batches is controlled within 40MPa, and the pure titanium wires meeting specific strength requirements are produced.

Description

technical field [0001] The invention relates to the field of manufacturing pure titanium materials, in particular to the manufacturing of pure titanium wires that require strength. Background technique [0002] Due to the advantages of high specific strength and good corrosion resistance, titanium materials are widely used in aerospace, aviation, medical and other fields. In recent years, with the development of titanium material production technology, the price has been greatly reduced, and titanium materials are gradually used in civilian industries. Spectacle frames made of titanium materials have entered the lives of ordinary people. At present, the titanium materials used in spectacle frames mainly include pure titanium and titanium alloys. Due to the high strength of titanium alloys, difficulty in processing and molding, and ordinary people's trust in the purity of precious metals, the application of pure titanium wires in spectacle frames still accounts for a large pa...
