Problems solved by technology

However, due to the violent reaction of the aluminothermic reduction method, prolonging the holding time increases the probability of impurities such as O, C, and N intruding into the alloy.

Embodiment 1

[0030] Take high-titanium slag and aluminum powder in a certain proportion, add absolute ethanol to grind and mix on a ball mill to obtain raw materials, then weigh 2 kg of raw materials, add lime and heating agent potassium chlorate, mix with raw materials evenly, and then put them into the reaction in the can. Add a layer of igniting agent on the surface of the mixture, start the stepless motor 1 after the ignition triggers the reaction, the stepless motor 1 drives the center shaft 5 to rotate, adjust the speed to 1500 rpm, turn off the motor after 30 minutes, and the reaction tank 9 follows the center shaft Slowly decelerate until the rotation stops, and return to the vertical state from the inclined state. After the reactant was cooled to room temperature, it was taken out, and the product was clearly divided into upper and lower layers with a clear interface, the upper layer was slag, and the lower layer was titanium-aluminum alloy. The product with the upper and lower l...

Abstract

The invention discloses a preparation method and preparation device of a titanium-aluminum alloy, and belongs to the field of preparation of the titanium-aluminum alloy by an aluminothermic reduction method. The invention provides a preparation method and a corresponding preparation device of the titanium-aluminum alloy, which can improve the residue-metal separation effect and the quality of the titanium-aluminum alloy; the titanium-aluminum alloy is prepared through an aluminothermic reduction reaction under a super-gravity system environment, so that the residue-metal separation effect can be improved. The preparation device comprises a reaction tank and a super-gravity generating system, wherein the super-gravity generating system comprises a support frame, a central rotating shaft, a rotating cross arm and a driving mechanism, the reaction tank is in hanging connection to the free end part, which is away from the central rotating shaft, of the rotating cross arm, through a steel rope. The reaction tank is driven by the driving mechanism to rotate around the axis of the central rotating shaft, so that performing an aluminothermic reaction in the reaction tank under the super-gravity field environment is realized. The preparation device disclosed by the invention is simple in structure, and super-gravity coefficients can convenient to regulate as needed.

Description

technical field [0001] The invention relates to the technical field of preparing titanium-aluminum alloys by an aluminothermic reduction method, in particular to a method for preparing titanium-aluminum alloys and a corresponding preparation device. Background technique [0002] Titanium has the advantages of light weight, high specific strength, good high temperature resistance and corrosion resistance, and is known as "space metal", "future metal" and "third metal". Pure titanium has good mechanical properties and processability, but its plasticity will be reduced when it contains O, C, and N. Because liquid metal titanium can dissolve almost all metals to form various alloys, titanium-aluminum alloys have attracted extensive attention from scholars at home and abroad. The aluminothermic reduction method, as a method in the high temperature self-propagating method, is widely used in the preparation of alloys. Such as Ti-Fe alloy, Ti-Al alloy, etc. The aluminothermic red...
