Embodiment 1

[0100] The production of Φ6.0mm titanium alloy wire rod using the above hot continuous rolling production line includes the following steps:

[0101] a. Heating: Hold the forged billet of titanium alloy with a size of 150×150×12000mm at a heating temperature of 1000℃ for 3h;

[0102] b. Rough rolling: rough rolling the heated forged billet at a rolling speed of 0.7m / s, rolling 4 passes, with a pass elongation coefficient of 1.2; the final rolling temperature of the rolled piece is controlled to 850℃;

[0103] c. Intermediate rolling: After the rough-rolled piece is cut to 50-100mm, the intermediate rolling is carried out, the rolling speed is 1.2m / s, the rolling pass is 6 passes, the pass elongation coefficient is 1.3; the final rolling temperature control of the rolling piece 830℃;

[0104] d. Finishing rolling: the rolled piece after the intermediate rolling is cut to 50-100mm before rolling, the rolling speed is 4.2m / s, rolling 6 passes, the pass elongation coefficient is 1.2; the ...

Embodiment 2~ Embodiment 3

[0109] According to the steps of Example 1, the process parameters were changed to obtain a Φ8.0mm pure titanium wire and a Φ10.0mm titanium alloy wire. Table 4 lists the specific production process parameters of Φ6.0mm titanium alloy wire, Φ8.0mm pure titanium wire, and Φ10.0mm titanium alloy wire. The products produced in Example 1 to Example 3 all comply with the diameter, cross-sectional thickness and size tolerances of titanium and titanium alloy rods and wires specified in the GB / T2965-2007 standard.

Abstract

The invention relates to a method for producing titanium and titanium alloy wires through hot continuous rolling, belongs to the technical field of metal plastic working, and aims to solve the technical problems and provide a method for producing titanium and titanium alloy wires on a traditional steel hot continuous rolling unit. According to the method for producing the titanium and titanium alloy wires through hot continuous rolling, a heating system, blooming temperature, rolling speed and hole pattern are controlled, processes including shearing, cooling and spinning to form coils are performed, and titanium and titanium alloy square billets are discharged from a furnace through single heating and rolled into wires with the diameter ranging from phi 5.5 mm to phi 20 mm. According to the method for producing the titanium and titanium alloy wires through hot continuous rolling, titanium and titanium alloy wire products with large single wire coil weight, good surface quality and roundness and uniform structure property can be produced quickly and efficiently on the hot continuous rolling unit.

Description

Technical field [0001] The invention relates to a method for producing titanium and titanium alloy wire rods by hot continuous rolling, and belongs to the technical field of metal plastic processing. Background technique [0002] With the development of metallurgical technology, electric transmission control technology, and mechanical manufacturing technology, high-speed wire rod rolling mills have also developed rapidly and have become the most mature bar and wire rod rolling equipment. Its characteristics are high speed, single wire, no twist, micro tension, combined structure, tungsten carbide roll ring and high degree of automation. Its product features are large disk, high precision and good quality. [0003] Titanium and titanium alloy is an important structural metal developed in the middle of the 20th century. It has low density, high specific strength, high temperature resistance, low temperature resistance, acid and alkali corrosion resistance, non-magnetic, low linear e...
