TA16 titanium alloy wire processing process

Abstract

The invention discloses a TA16 titanium alloy wire processing process. The TA16 titanium alloy wire processing process comprises the following steps of: extracting, rolling, high-temperature rounding,high-temperature drawing and room-temperature drawing, thereby obtaining the TA16 titanium alloy wire with a diameter being Phi 1.0 mm. According to the TA16 titanium alloy wire processing process disclosed by the invention, the high-temperature rounding step is increased, so that ovality of the rolled wire is reduced through a wire rod with a diameter being Phi 9.5 mm while a rolled back-skin wire is heated to a high temperature being about 800 DEG C, and therefore, the yield is increased; the skin of the high-temperature rounded wire is pulled off through a centerless lathe, and skin of thehigh-temperature drawn wire is pulled off through high-temperature wire drawing, so that surface defects can be effectively reduced, and the surface grain size and roughness of the wire are ensured;and compared with a conventional process, the TA16 titanium alloy wire processing process has the advantages of cancelling a plurality of acid-floating and manual-grinding processes in a white-skin wire processing process as well as a process of performing acid-alkaline washing while the wire is drawn to be 3.0 mm, so that the environmental protection purpose is realized, and working hours can bereduced by 1 / 3.

Description

technical field [0001] The invention relates to the technical field of titanium alloy processing, in particular to a TA16 titanium alloy wire processing technology. Background technique [0002] In the traditional titanium alloy wire processing technology, in the white skin wire processing stage, in order to ensure that the surface defects of the wire are cleaned up, multiple stages of acid bleaching and manual grinding are required, and when the wire diameter is drawn to 3.0mm, another Acid and alkali cleaning to ensure a good surface of the wire. For example, the Chinese invention patent with the publication number CN103480685A published on January 1, 2014 is called a processing method of TC18 alloy wire, including vacuum melting, upsetting forging, precision forging, heat treatment, rolling, annealing, and rounding , Mechanical peeling, pickling and grinding, multiple vacuum annealing and stretching. This patent has the following disadvantages compared with the traditio...
