Abstract

A continuous production method and device in a one-step furnace for hypo / hypereutectic γ-titanium-aluminum-vanadium alloy belongs to the technical field of special self-propagating metallurgy. The one-step furnace continuous production device for hypo / hypereutectic γ-titanium-aluminum-vanadium alloy is divided into heating reaction zone (heating and supplementary heat), cooling zone (transition reaction zone and complete reaction zone) and transmission system. Electromagnetic induction heating of vanadium alloy powder raw materials induces a self-propagating reaction, and according to different stages of the reaction, furnace temperature, reactor temperature and temperature rise rate, the automatic lifting and lowering of materials in different areas is realized through transmission, and then graded heating and graded cooling. The method realizes the one-step continuous production of hypoeutectic, hypereutectic and eutectic γ-titanium-aluminum-vanadium alloys by regulating the composition ratio in materials and the heating and cooling processes. This method solves the key problems of self-propagating vacuum synthesis of γ-titanium-aluminum-vanadium alloy with a scale of Ф50~Ф100, explosiveness, difficult separation of slag and gold, high oxygen content of the product, and discontinuous production process.

Description

technical field [0001] The invention belongs to the technical field of special self-propagating metallurgy, and specifically relates to a continuous production method and device in a one-step furnace for hypo / hypereutectic γ-titanium-aluminum-vanadium alloy. Background technique [0002] According to the classification of phase diagram, titanium aluminum alloy can be divided into: α titanium aluminum alloy (Ti3Al), β titanium aluminum alloy (TiAl3), γ titanium aluminum alloy (TiAl). Titanium aluminum alloy has excellent properties such as low density, excellent high temperature strength, good oxidation resistance and creep resistance. Among them, γ-titanium-aluminum alloy has obvious advantages over the other two types of alloys. It has lower density and higher strength than α-titanium-aluminum alloy, and has better high temperature resistance than β-titanium-aluminum alloy. Therefore, the comprehensive properties of γ-titanium aluminum alloy, such as ultra-strong, ultra-li...
