specific Embodiment approach 2

[0028] Specific embodiment two: this embodiment is different from specific embodiment one in that: the oscillating electric signal with a frequency of 20KHz is generated by the ultrasonic generator 16, which is transmitted to the transducer 5 through the ultrasonic output cable, and the electric signal is transmitted to the transducer 5 by the transducer 5. The signal is transformed into mechanical vibration to drive the fixed frame 6, the connecting rod 3 and the upper feeding transmission device 2 to jointly adjust the working position of the ultrasonic oscillation equipment.

[0029] The amplitude of the mechanical vibration is about 7 to 9 μm, and the amplitude is amplified to 17.5 μm to 22.5 μm after passing through the aluminum alloy horn 7. After the amplification, the ultrasonic wave is exported by the T8 steel tool head 8, and the ultrasonic wave acts on the molten bar On the layer 13, the horn 7 is made of aluminum alloy, and the tool head 8 is made of T8 steel consid...

specific Embodiment approach 3

[0031] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the range of adjustable motion speed of the upper feeding transmission device 2 is 0-20 mm / min.

[0032] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Description

technical field [0001] The invention relates to a pollution-free and high-efficiency refining alloy device, in particular to a titanium-aluminum alloy refining device. Background technique [0002] As a new melt processing technology, ultrasonic has no pollution and high efficiency, which meets the requirements of current science and technology and social development for environmental protection and recyclable materials. Ultrasound, as a mechanical wave, must be introduced into the melt with a conductive medium in the middle. According to different media, it can be divided into direct introduction and indirect introduction. Direct introduction means that the ultrasonic tool head directly acts on the melt, and indirect introduction refers to the ultrasonic tool head. There is an intermediate medium between the melt and the melt. According to the position of the introduction method, it can be divided into upper introduction, side introduction and bottom introduction. The most...
