15-ton inverted-U-shaped combination device and production process for producing sponge titanium

Abstract

The invention relates to a 15-ton inverted-U-shaped combination device and a production process for producing sponge titanium. The 15-ton inverted-U-shaped combination device is composed of a reaction furnace, a reactor 28, a reactor cover 11 and a cooling water jacket 25, wherein the reactor 28 comprises a cold-end reactor and a hot-end reactor which are arrayed in parallel; the two reactors are communicated via the reactor cover 11 above; the cold-end reactor is located in the cooling water jacket 25; and the hot-end reactor is located in the reaction furnace. A large furnace has the advantages of being low in energy consumption, high in capacity, stable in quality, and high in labour productivity; and with the progress of a production technology for sponge titanium, the furnace profile is developed towards a large-size direction. The invention provides a 15-ton inverted-U-shaped combination device and a production process for sponge titanium.

Description

technical field [0001] The invention relates to a titanium sponge reduction distillation reaction device, in particular to a 15-ton inverted U-shaped combined device for producing titanium sponge and a production process. Background technique [0002] At present, the main process of sponge titanium production is magnesia thermal reduction method. The basic principle is to add titanium tetrachloride to the reactor to react with magnesium under the protection of argon to generate sponge titanium and magnesium chloride, and then remove them by vacuum distillation. Impurities such as magnesium and magnesium chloride in the sponge titanium are obtained to obtain pure sponge titanium. [0003] Due to the complex production process of titanium sponge, the production cost is high. In particular, the production process of sponge titanium uses a small furnace with high raw material consumption, small production capacity, low pass rate, and high energy consumption. Sponge titanium man...

AI Technical Summary

Problems solved by technology

[0004] Domestic inverted U-shaped furnaces have reached 10 tons of single furnace production capacity after decades of exploration, but there are still many problems. The level is much higher than that of foreign countries. Secondly, there is a serious hard core problem in titanium lumps. The porosity of the product is poor. The hard core usually contains high chlorine elements, which seriously affects product quality.

The hard core is rarely broken, and it is very difficult for downstream customers to press the electrodes, which affects customers' evaluation of quality

In addition, the production process does not match the equipment, resulting in problems such as low yield rate and low rate of superior products.
