Method of producing aluminium titanium alloy using aluminium electrolytic tank

Abstract

The invention relates to a method to produce aluminum titanium alloy by using aluminum electro-bath. The feature is that the raw material is alumina and titanium dioxide, and the purity of alumina should over 98%, as well as titanium dioxide; selecting cryolite molten salt aluminum electro-bath; adding alumina and titanium dioxide into the electro-bath to liquating into the cryolite melt, and the consistency of alumina is 2-5%, the titanium dioxide is below 1%. Under the effect of DC, the metallic aluminum and metallic titanium would be separated out on the cathode of the electro-bath. The equal aluminum titanium alloy would be formed under the whisking of magnetic field force of electro-bath. Aluminum absorbing package would absorb the alloy out and cast into aluminum titanium alloy bullion. The advantage of the invention is low energy consumption, low cost, high content of titanium in the alloy that could reach 2.5% and the actual recycle ratio of titanium could reach 98%.

Description

technical field [0001] The invention relates to a method for producing an aluminum-titanium alloy by using an aluminum electrolytic cell, and belongs to the field of aluminum electrolysis production methods. Background technique [0002] The production of aluminum-titanium alloys generally adopts the fusion method in industry, that is, the metal aluminum and metal titanium are melted and mixed together in proportion, and then cast into aluminum-titanium alloys. This method consumes a lot of energy, costs high, and the yield of titanium is low, and the yield of titanium is only about 85%. At present, there is another method that is to add titanium dioxide to the anode ingredients to make a carbon anode. , Titanium dioxide enters the electrolyte with the consumption of the anode, and then undergoes electrolysis, and precipitates together with aluminum at the cathode to form an aluminum-titanium alloy. The titanium content in its alloy is up to 0...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the anode resistance is large, the energy consumption is high, due to the addition of titanium, the compressive strength of the anode is small, the quality of the anode is poor, the consumption increases, the production cost increases, and the content of titanium in the aluminum-titanium alloy is low.
