Piezoelectric ultrasonic/high-frequency electromagnetic hybrid suspension non-contact smelting method and device

Abstract

The invention relate to a piezoelectric ultrasonic / high-frequency electromagnetic hybrid suspension non-contact smelting method and a device, which belong to the technical field of non-contact material smelting. The device comprises a sealing box, an ultrasonic generator, an ultrasonic transducer, a high-frequency inductive power source, a high-frequency inductor, a base, deflating and inflating equipment, an infrared temperature measurer, a pressure gauge, an ultrasonic wave reflecting end and an adjusting device of the ultrasonic wave reflecting end. Ultrasonic suspension force and electromagnetic suspension force jointly act on suspended particles (metal), or the electromagnetic suspension force independently acts on the suspended particles, and the suspended particles generate electromagnetic induction in a high-frequency magnetic field generated by the high-frequency inductor, and are heated until the suspended particles are melted. The output power of the high-frequency power source is reduced, a melted article independently acts under the effect of the ultrasonic wave suspension force, and is cooled to form solid in a suspension state. Smelting of materials is completed in a state without a container, high-purity alloy without impurities can be prepared, and non-contact smelting of metal with active chemical properties can be carried out.

Description

technical field [0001] The invention relates to a piezoelectric ultrasonic / high-frequency electromagnetic hybrid levitation non-contact smelting method and device, belonging to the technical field of material non-contact smelting. Background technique [0002] With the deepening of condensed matter physics research, people's requirements for the experimental environment are getting higher and higher. The space environment is such a special environment, and its microgravity and ultra-high vacuum effect are very ideal experimental conditions for the non-contact processing of materials. Since the 1970s, the rapid development of aerospace technology has provided people with more and more opportunities for space experiments. The space shuttle can provide a weightless environment for non-contact treatment of various materials, high-purity alloys and non-polluting treatment of chemically active metals. However, the cost of using the space shuttle is too high, and the space resour...
