Description
Technical Field
The invention relates to a production device of titanium sponge, in particular to a heating and radiating furnace for reduction production of titanium sponge.
Background
The titanium sponge is produced by a Claur method, titanium tetrachloride is reduced by high-temperature liquid magnesium in a closed container, the titanium sponge is produced by a chemical production method, and the titanium sponge is subjected to contact reaction at the upper part of the closed container (the upper part and the lower part) and releases a large amount of waste heat. Magnesium chloride and titanium sponge are generated, the magnesium chloride is discharged from the closed container step by step during the reduction period, and after the reduction production is finished, the titanium sponge, the residual small amount of magnesium and the magnesium chloride in the container enter the next process production. Because the reduction production method is an exothermic reaction, high temperature is generated in a reaction area, the sponge titanium has a compact structure after being sintered due to the high temperature, the period of the next process production is prolonged, the quality of the sponge titanium product is reduced, the power consumption production cost of the sponge titanium is increased, and the waste heat of the reaction must be discharged out of the closed container during the reduction production, so the heat dissipation must be carried out on the upper part of the closed container; the magnesium chloride is deposited at the bottom of the closed container, and when the magnesium chloride is discharged, the lower part of the closed container is required to reach more than 800 ℃ to normally discharge the magnesium chloride to ensure that the magnesium chloride is in a liquid state. From the requirement of the whole sponge titanium reduction production process, the upper part of the closed container must be subjected to heat dissipation and lower part heating. The prior art is that the reduction distillation furnace is integrated, the heating element is arranged at the upper part and the lower part of the reduction distillation furnace at the same time, a heat radiating device is arranged at the upper part of the reduction distillation furnace during reduction, and the upper part of the closed container is ventilated for radiating heat; the whole reduction distilling furnace uses heating elements and heat-insulating layers, so that the manufacturing cost of the reduction distilling furnace is increased.
Disclosure of Invention

The beneficial effect of adopting above-mentioned technical scheme is:
1. the invention realizes the heat dissipation of the upper part of the closed container only when the titanium sponge is produced, reduces the sintering of the titanium sponge structure, shortens the production period, reduces the production power consumption and improves the quality of the titanium sponge product.
2. The invention realizes that only the upper part of the reduction furnace is radiated when the titanium sponge is produced, thereby avoiding the corrosion of oxygen in the air to the heating element and saving the production cost.
