Embodiment 1

[0022] Such as figure 1 Shown is a schematic diagram of the structure of the annular zone smelting furnace of the present invention. The ring-shaped area melting furnace includes: furnace cover 7, vacuum chamber 6, quartz ring-shaped area melting boat 5, heating coil 10, high-frequency power supply 11, vacuum system 4, protective gas input device 3, supporting steel ring 2, temperature measurement With temperature control system 9 and rotating drive system 1. The quartz ring zone melting boat 5 has a ring structure and is made of quartz or graphite materials. It is placed in a support steel ring 2 with a similar appearance. The rotating drive system 1 includes a drive motor, a reducer and a transmission link connected to it. , The supporting steel ring 2 is connected with the transmission connecting rod in the rotating drive system 1, and the speed is continuously adjustable. The center line of the heating coil 10 is turned to a horizontal position, the heating coil 10 is fixed, ...

Embodiment 2

[0026] Others are the same as Embodiment 1, except that: the quartz ring zone melting boat 5 of the present invention is replaced with an upright melting crucible, and a corresponding mold can be set under the melting crucible according to the required shape and size; and the heating coil is installed On a bracket that can adjust the angle of 360°, the position of the heating coil can be rotated to heat the upright smelting crucible for smelting and casting operations. Since the heating coil is connected to the high-frequency power supply, the heating coil induction heating ensures the heat required for smelting the material, increases the heating speed, accelerates the melting speed, and effectively reduces the energy consumption. After the materials in the smelting crucible are melted by induction, pour the melt in the smelting crucible into the mold to cool, and the casting operation can be completed.

Description

Technical field [0001] The invention relates to an annular zone smelting furnace, which can be used for zone smelting and smelting ingot casting operations, and integrates multiple functions of material purification, single crystal preparation, smelting and die casting. Background technique [0002] The most important purpose of zone smelting is to purify metals. Due to the increase in purity of high-purity metals, many of its chemical and physical properties have changed, which fully demonstrates the inherent characteristics of metals. With the development of information and electronic technology, the application of high-purity metals has become more and more extensive. Especially in the preparation of high-performance compound semiconductors, the purity requirements of metal materials have become higher and higher. Zone smelting provides an effective and easy method for the preparation of pure metals. Through zone smelting and purification, at present, more than 1 / 3 of the elem...
