Described method two roller tandem rolling units adopt full continuous rolling, and pass schedule adopts ellipse-side, ellipse-circle, passage mean coefficient of elongation 1.1-1.4, and finishing temperature is controlled at 500-850 ℃.Two roller tandem rolling units can go out pure titanium pole material and square rod and other profile bar material of Φ 40-10mm, and the substance of bar is less than 100kg; Also can go out the line base of Φ 20-10mm, substance is less than 100kg, for rolling little line base provides the line blank.

Described method does not have and turns round two roller tandem rolling units and adopt full continuous rolling, adopts ellipse-circular hole system, passage mean coefficient of elongation 1.05-1.4, and finishing temperature is controlled at 500-850 ℃.

Described circular hole adopts tangent line expansion, angle of flare 20-35 °

The frame of described full tandem mill is by the variable-frequency motor speed governing, and it is rolling to part power between frame a little.

Compare with traditional handicraft, the present invention has the following advantages:

1, with heating once and rolling pure titanium rod wire rod, energy consumption reduces more than 3 times, and production efficiency improves more than 10 times.

2, pure titanium rod wire cross-section dimensional accuracy improves 2 times, (deviation by ± 0.8mm bring up to ± 0.4mm)

3, the substance of pure titanium rod wire rod improves more than 10 times.

4, the structure property of pure titanium rod wire rod is good.
