Electron beam zone melting furnace and method for carrying out float zone purification on material

Abstract

The invention relates to an electron beam zone melting furnace and a method for carrying out float zone purification on a material. The electron beam zone melting furnace comprises a furnace body arranged on a work table, an annular electron gun arranged in the furnace body, and a material fixation device arranged in the furnace body, wherein the annular electron gun sleeves on the outer cycle of a material during melting, a refrigeration system, a vacuum unit and a rocker arm mechanism of a control panel are arranged, the material fixation device comprises a pair of rotatable rod material clamping heads fixed on the upper end and the lower end of the furnace body and capable of being adjusted up and down, an electron gun lifting system capable of driving the electron gun to move up and down during melting is further provided and at least comprises a set of screws respectively driven by a servomotor and a supporting and placing plate for the electron gun, the pair of the double screws are respectively arranged on both sides of the material during melting, and the supporting and placing plate for the electron gun is horizontally fixed on the pair of the double screws. According to the present invention, the melting furnace adopts the electron beam to carry out float zone purification on the material difficultly melting at a high temperature, such that the difficult problems that purification of the material difficultly melting at the high temperature, crystal production and the like can not be achieved only with the current resistance zone melting furnace and the sensing zone melting furnace are solved.

Description

technical field [0001] The invention relates to an electron beam zone melting furnace, in particular to a melting furnace and a method for purifying high-temperature refractory materials in a suspension zone through electron beams. Background technique [0002] With the rapid development of science and technology, the requirements for the purity of high-temperature refractory materials and the integrity of crystals are getting higher and higher. As we all know, trace impurities have a serious impact on the physical and chemical properties of materials, and the various unique properties of materials when they are ultra-pure are just what modern cutting-edge technologies are demanding. Therefore, in order to achieve the above-mentioned material process performance, the electron beam zone furnace was born to meet the call of the times. [0003] In order to obtain ultra-pure high-temperature refractory materials, the melting equipment needs at least three basic conditions: firs...
