Embodiment Construction

[0025] The invention provides a feeding method for a molten salt electrolysis titanium high temperature furnace. see figure 1 , the molten salt electrolytic titanium high-temperature furnace feeding device used comprises casing, leak hopper 17, metal hose 18 and leak steel pipe 19, wherein the inner diameter of leak steel pipe is 46mm, and the outer diameter is 50mm considering the electrolysis speed, the feeding The speed has a great influence on the quality of the electrolysis product. Controlling the inner diameter of the leaking steel pipe can directly control the amount of feed, thereby controlling the electrolysis speed and keeping the raw materials in the electrolysis cell stable within a certain range. In the prior art, the speed of feeding is not clearly defined. The applicant found in production that too fast and too slow feeding will lead to the quality of the electrolysis product. The inner diameter of the leaking steel pipe used in the present invention can be wel...

Abstract

The invention provides a titanium high-temperature feeding method for use in molten slat electrolysis. When the method is used, the material leaking speed can be well controlled, the continuous electrolysis and the stability of an electrolysis process can be guaranteed, raw material titanium dioxide can be supplied constantly in an electrolysis process, continuous titanium electrolysis can be realized, and production cost is lowered greatly.

Description

technical field [0001] The invention relates to a feeding method, in particular to a feeding method for a molten salt electrolytic titanium high temperature furnace. Background technique [0002] Titanium and titanium alloys have excellent properties such as light specific gravity, high specific strength, good creep resistance at high temperature, and corrosion resistance. They are widely used as structural materials in aerospace, metallurgy, automobile and other industries, and can also be used as functional materials such as hydrogen storage materials, shape memory alloy materials, etc. At present, the production process of sponge titanium is the Kroll method, also known as the magnesium thermal reduction method. This method is to first prepare titanium tetrachloride from titanium-containing minerals, and then reduce titanium tetrachloride with magnesium to obtain sponge titanium. Vacuum consumable electric arc melting is used to make dense titanium ingots, and then the f...
