Abstract

The invention provides a production method of an industrial pure titanium wire rod, which comprises the following steps of heating of an industrial pure titanium square billet, rough rolling, middle rolling, prefinish rolling, finish rolling, spinning in circles, wind cooling, coil collection and air cooling, and then the industrial pure titanium wire rod is obtained. The industrial pure titanium wire rod, the piece weight of which exceeds 400 kg, can be produced, the production efficiency and the yield of the industrial pure titanium wire rod are effectively increased, the problems of easiness in oxidation and hydrogen embrittlement of industrial pure titanium in prior art are solved, the heating cost of the industrial pure titanium square billet is effectively reduced, continuous production on a large scale can be realized, the rolling speed and the rolling power are increased, and an ideal metallographic structure and physical properties are obtained. By utilizing the method, the industrial pure titanium wire rod with large coil weight can be efficiently produced, the precision of the product size is high, and the structure property is good.

Description

[0001] technical field [0002] The invention relates to a rolling method, in particular to a production method of industrial pure titanium wire rod, which belongs to the technical field of processing and forming of nonferrous metal materials. Background technique [0003] Titanium and titanium alloy wires are widely used in aerospace, automobiles, tool connectors, medical equipment and other fields due to their excellent corrosion resistance, high specific strength, and strong human affinity. The production of titanium and titanium alloy wires and wires usually adopts a discontinuous rolling method. Titanium and titanium alloys are hot-rolled into wires and wires of φ6 to φ10, and then stretched into wires or wires of required specifications. The existing production methods of titanium and titanium alloy wires and wire blanks are generally forging or rotary forging, both of which require multiple heating, high energy consumption, high labor intensity, low production efficie...
