Device and method for manufacturing semi-hard or soft tantalum wire

The invention discloses a method and a device for manufacturing a semi-hard or soft tantalum wire. The device comprises an unwinding device, an annealing device and a winding device; the unwinding device comprises unwinding wheels and guide wheels located at an inlet of the annealing device; the winding device comprises winding wheels and guide wheels located at an outlet of the annealing device;the annealing device comprises an upper guide box, a heat insulation box and a lower guide box sequentially from top to bottom; inner guide pipes are arranged inside the upper guide box and the lowerguide box; and a lifting cabinet type heater is arranged inside the heat insulation box and comprises guide columns, upper fixed connection blocks, resistance wires and lower fixing plates from top tobottom. The invention further discloses the method for manufacturing the tantalum wire. The tantalum wire is annealed inside the heater at the temperature ranging from 1,150 DEG C to 1,250 DEG C, winding is performed while unwinding, and the hard tantalum wire can be changed into the semi-hard or soft tantalum wire according to the different winding speeds. By the aid of the device and the method, straightening can be avoided after annealing of the tantalum wire, double purposes can be achieved through one effort, and thus the production efficiency is high.
