Abstract

An ultrasonic-assisted fusing device and a fusing method for vacuum ultra-high temperature refractory active materials relate to a fusing device and a fusing method. The invention solves the problem that the existing ultrasonic equipment reacts with the ultra-high temperature refractory active material alloy at high temperature, pollutes the ultra-high temperature refractory active material alloy melt, and damages the ultrasonic equipment. The ultrasonic generator of the present invention is installed in the furnace body, the water-cooled copper crucible is installed on the ultrasonic generator, the raw material is installed on the water-cooled copper crucible, the non-consumable electric arc furnace extends through the furnace body into the furnace body, and the pressure gauge is installed in the furnace body on the upper end face and communicates with the inside of the furnace body. The non-consumable arc gun is fed into single-phase alternating current for heating; the power of the non-consumable arc gun is reduced, and ultrasonic waves are introduced into the molten raw materials in the water-cooled copper crucible; after the ultrasonic treatment is completed, the power is reduced to a minimum, Then turn off the power. The invention is used for ultrasonic-assisted fusing of vacuum ultra-high temperature refractory active materials.

Description

technical field [0001] The invention relates to an ultrasonic-assisted fusing device and a fusing method, in particular to an ultrasonic-assisted fusing device and fusing method for regulating the microstructure of titanium-aluminum, niobium-silicon, and high-entropy alloys and improving mechanical properties. Background technique [0002] As a new melt processing technology, ultrasonic wave is pollution-free and high-efficiency, which meets the requirements of current science and technology and social development for environmentally friendly and recyclable materials. In order to introduce ultrasonic waves as mechanical waves into the melt of ultra-high temperature refractory active materials, there must be a conductive medium in the middle. According to the difference of the medium, it can be divided into direct introduction and indirect introduction. Direct introduction means that the ultrasonic tool head directly acts on the melt and indirectly. Introduction means that th...
