Technical Field
[0001] The utility model relates to the technical field of titanium sponge production, in particular to a titanium sponge heating device. Background Art
[0002] Sponge titanium is a raw product of titanium metal, which is often used to prepare other titanium products. Sponge titanium is extracted from titanium ore by a reduction process, and its name comes from its porous appearance, which is similar to a sponge. Sponge titanium usually exists in powder or block form. Due to its high reactivity and purity, it is often used as a starting material for the preparation of other titanium alloys and chemicals. During the preparation process, sponge titanium usually needs to be refined and processed before it can be used to manufacture various titanium products, such as aerospace parts, medical equipment, chemical equipment, etc. Heating can provide the required temperature to promote the reduction reaction, so that the chemical reaction between titanium dioxide and the reducing agent can proceed smoothly, thereby producing sponge titanium. In addition, by controlling the heating process, the reaction rate and temperature can also be controlled, which helps to improve the purity and uniformity of the product. Therefore, the heating device is indispensable in the production process of sponge titanium.
[0003] Currently, most titanium sponge heating devices are composed of a heating device, a reaction vessel, and an exhaust pump structure. Since titanium sponge needs to be heated in a vacuum environment, the reaction vessel and the container cover need to be fixed with bolts.

As a result, the sealing ring will be deformed or worn during the high-temperature heating process of the titanium sponge, which will cause oxygen to enter through the gap between the reaction vessel and the container cover. As a result, the oxygen will react with the titanium sponge at high temperatures to generate oxides, further reducing the production quality of the titanium sponge. Therefore, the present application proposes a titanium sponge heating device to solve the above problems. Utility Model Content

Before heating, the first valve 18 is opened, and the inner wall of the reaction container 27 is evacuated to a vacuum through the vacuum pump 17 to prevent the air inside the reaction container 27 from containing oxides, which will react with the sponge titanium at high temperatures and reduce the production quality of the sponge titanium. Then, the second valve 20 is opened to discharge the cooled water through the drain pipe 19. At the same time, the non-magnetic furnace seat 22 can prevent the magnetic field from Interference, thereby making the stability of the internal processing, the anti-slip pad 23 can prevent the danger of the entire device tipping over, and then the support column 24 supports the furnace body 1, improving the stability of the furnace body 1, and then the refractory board 21 has good high temperature resistance, which can keep the reaction container 27 stable under high temperature environment, and by installing the intermediate frequency power supply 11 on the inner wall of the fixed plate 10, and then connecting the positive and negative poles of the wire 12 to the induction coil 26, and then plugging the card block 14 into the inner wall of the connecting block 13, further rotating the card block 14, and at the second spring 25 Under the action of, the movable clamp head 15 is clamped in the groove of the inner wall of the clamp block 14, and the induction coil 26 on the inner wall of the furnace body 1 is distributed on the outside of the reaction vessel 27.
