The invention discloses a method for annealing titanium wire material, wherein the annealing of the titanium wire material is carried out in the annealing device, which is characterized in that the annealing device comprises a shell with a cavity; The cooling part is arranged on the first inner wall of the shell; The quartz tube, one end of the quartz tube is installed on the cooling part, the other end is installed on the second inner wall of the shell and the first inner wall relative, and the quartz tube is arranged on the cooling part of the position is provided with an air inlet, the quartz tube is arranged on the position near the second inner wall is provided with an air outlet; A conveying channel extending from the second inner wall of the shell to the first inner wall of the shell, and through the cooling part and the quartz tube from the inside; The induction coil is wound around the outer circumference of the quartz tube; Wherein, through the quartz tube set on the air inlet and outlet into the quartz tube under the condition of inert gas, the titanium wire material through the conveying channel, wherein, in the titanium wire material through the quartz tube process, through the induction coil of the titanium wire material is heated, so that the temperature of titanium wire material is controlled at 500_900°C, And the speed of the titanium wire material through the conveying channel is 0.2m/min~1.5m/min.
By using the annealing treatment method of titanium wire material of the invention, only the wire (drawing blank) is subjected to alkali pickling, and the subsequent drawing production process does not need alkali pickling and acid pickling processes, so as to reduce the process and improve the efficiency. And because the metal loss caused by alkali pickling is reduced, the use of alkali acid is reduced, thus the cost is low, and the environmental pollution can be reduced.
By being disassembled and installed on the other end of the quartz tube, the front port part suitable for the titanium wire material can be further switched according to the thickness of the titanium wire material 6. Moreover, the diameter of the through hole at the front port 6 is preferably smaller than that of the through hole at the conveying channel 4, so as to improve the pressure of inert gas in the quartz tube.
