Problems solved by technology

[0002] In the current domestic market, the production method of titanium wire is still dominated by the hole die drawing process. This process is mainly due to high energy consumption, low efficiency, small unit weight, and low yield. Pollution and other problems, with the increasing market demand for titanium wire and the gradual improvement of quality requirements, the traditional hole die drawing process has been difficult to meet the market demand

Abstract

The embodiment of the invention provides a method for processing large single-weight titanium and titanium alloy wire rods. Bar billets are processed by adopting a billet preparation technology of titanium alloy large single-weight wire rods, a multi-die drawing technology, and a continuous annealing technology under inert gas protection to finally obtain the titanium alloy wire rods. Compared with the titanium alloy wire rods manufactured by a traditional hole die drawing process, the titanium alloy wire rods manufactured by the processing method have the advantage of better stress state, andwith compressive stress as the main and tensile stress as the supplement, grains in the titanium alloy wire rods are effectively refined, the hollow phenomenon is completely eliminated, and then thetitanium alloy wire rods with a good metallographic structure are obtained. The test report shows that the mechanical property deviation of the titanium alloy wire rods of the same batch, manufacturedby the processing method, is about 5%, which improves the stability and the consistency of the titanium alloy wire rods.

Description

technical field [0001] The invention belongs to the technical field of processing methods for titanium alloy materials, and in particular relates to a processing method for large single-weight titanium and titanium alloy wires. Background technique [0002] In the current domestic market, the production method of titanium wire is still dominated by the hole die drawing process. This process is mainly due to high energy consumption, low efficiency, small unit weight, and low yield. Pollution and other problems, as the market demand for titanium wire rods continues to increase and the quality requirements are gradually improved, the traditional hole die drawing process has been difficult to meet the market demand. Based on this situation, by tackling key problems in the preparation process of large single-weight titanium and titanium alloy bright drawing, this series of problems has been fundamentally solved, and the realization of market technology, production efficiency, res...
