Manufacturing technology method of titanium and titanium alloy bar wires used for manufacturing additional materials

Abstract

The invention provides a manufacturing technology method of titanium and titanium alloy bar wires used for manufacturing additional materials. The method comprises the following specific steps that needed raw materials are smelted, sponge titanium and an intermediate alloy are weighed, the raw materials are added into a mixing machine to be mixed uniformly, and obtained bars for EB smelting are subjected to ingot casting to obtain EB cast ingot blanks; the surfaces of the obtained EB cast ingot blanks are machined mechanically, the removing thickness of the milled surfaces is 2-5 mm, and surface defects are subjected to coping and polishing treatment; and bars and wires are obtained by means of one fire time and multiple fire times and metal pressure machining treatment, and among the different fire times, a straightening machine carries out online straightening, and a centerless lathe carries out scaling and polishing. The manufacturing technology is simple and low in cost, the obtained bar wires contain low content of impurity elements such as O and N, the component is more pure, and the comprehensive performance of additional material manufacturing parts is effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of material processing, and in particular relates to a process method for preparing titanium and titanium alloy rods and wires for additive manufacturing. Background technique

[0002] 3D printing additive manufacturing is an advanced, efficient, and near-net-shape component production method with high material utilization. It can produce thin-walled, complex cavities and lattice structures that cannot be prepared by traditional processes, meeting individual needs and developing prospects broad. Titanium alloy is the most commonly used metal material in 3D printing. It has the characteristics of low density, high specific strength, excellent corrosion resistance, and good biocompatibility. It has broad application prospects in daily necessities and other fields. However, due to titanium's high activity, high strength, and difficulty in deformation, traditional manufacturing and processing of titanium alloy...
