Embodiment 1

[0030] figure 1 It shows a device for rapid preparation of multi-component alloy materials with continuously changing composition by microwave, including a metal powder storage system, a feeding pipeline 1, a microwave melting system and a control system. The metal powder storage system is a box-type storage, and the box-type storage The top is provided with a plurality of metal powder storage bins 2, the metal powder storage bin 2 stores the metal powder of a single element, for the convenience of its installation, such as figure 2 As shown, its cross section is a regular hexagon, so the number of metal powder storage bins 2 placed in the same area is more. A flow control valve 3 is arranged at the bottom of each metal powder storage bin 2, a powder mixer 4 is arranged below the flow control valve 3, a stirring device 5 is arranged in the powder mixer 4, and a control panel 6 is arranged on the box-type storage.

[0031] The microwave melting material system includes an out...

Embodiment 2

[0044] Weigh 600 mesh 5kg metallic pure aluminum powder, 600 mesh 1.5kg metallic pure magnesium powder, 600 mesh 1.5kg metallic pure gallium powder, 600 mesh 1.5kg metallic pure tin powder. Put the above-mentioned raw material powder into the metal powder storage bin 2 in the box-type storage respectively for subsequent use.

[0045] The flow control valve 3 is controlled by the control system, so that the powders in the four metal powder storage bins 2 flow down at different speeds, and at the same time, the rotation of the stirring device 5 in the powder mixer 4 is controlled, so that the Mg, Ga, and Sn contents range from 0% to 0%. Fully mixed powder of Al-Mg-Ga-Sn metals varying in the range of 5%.

[0046] At the same time, the control roller 8 rotates, and the mixed powder enters the filling area 11 through the feeding pipeline 1 . The microwave generator 12 is controlled to heat the powder, and it flows downwards driven by the rotation of the roller 8. When the roller ...

Embodiment 3

[0049] Weigh 200 mesh 5kg metal pure aluminum powder, 200 mesh 2kg metal pure magnesium powder, 200 mesh 2kg metal pure gallium powder, 200 mesh 2kg metal pure tin powder, 200 mesh 2kg metal pure indium powder. Put the above-mentioned raw material powder into the metal powder storage bin 2 in the box-type storage respectively for subsequent use.

[0050] The flow control valve 3 is controlled by the control system, so that the powders in the five metal powder storage bins 2 flow down at different speeds, and at the same time, the stirring device 5 in the powder mixer 4 is controlled to rotate, and then the contents of Mg, Ga, Sn, and In are obtained from 0 % to 8% Al-Mg-Ga-Sn-In metal well mixed powder.

[0051] At the same time, the control roller 8 rotates, and the mixed powder enters the filling area 11 through the feeding pipeline 1 . The microwave generator 12 is controlled to heat the powder, and it flows downwards driven by the rotation of the roller 8. When the roller...

Abstract

The invention discloses a device and method for rapidly preparing a multi-component alloy material with continuously-changed components through microwaves, and relates to the technical field of alloy material processing. According to the device, under the action of a flow control valve, metal powder with different components is fed into a powder mixer in proportion and enters a filling area through a feeding pipeline after being evenly mixed through a stirring device 5 under the protective atmosphere, a wave absorbing material on a rolling wheel absorbs emitted waves of a microwave generator to heat the metal powder, meanwhile, the metal powder is small in particle size, the microwave penetration depth is equivalent to the particle size, vortex current is formed on the particle surface, the vortex current loses heat to quickly melt the metal powder, and the whole metal powder is uniformly sintered and melted. The metal melt in a molten state moves downwards to an air exhaust pipeline along with the roller, is vacuumized by a vacuum pump to eliminate bubbles in the melt, is conveyed to a discharge port, is slowly condensed by a cooling system, and enters a throwing device through a conveying pipeline at the same time, so that an alloy material with continuously changed components is obtained.

Description

technical field [0001] The invention relates to the technical field of alloy material processing, in particular to a device and method for rapid preparation of multi-element alloy materials with continuously changing composition by microwave. Background technique [0002] With the continuous development of my country's economy, various performance requirements are constantly put forward for materials, which promotes the development of materials in many aspects such as high specific strength, high specific hardness, high specific toughness, high temperature resistance, and corrosion resistance. Metal composite materials can greatly improve the thermal expansion, strength, fracture toughness, impact toughness, wear resistance, electrical properties and many other properties of a single metal material. However, the research and development of metal materials usually relies on traditional material methods such as trial and error methods. The existing method of preparing metal co...
