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.
