Electromagnetic Induction Internal Heating Type Magnesium Vacuum Reduction Furnace

Abstract

The invention relates to the technical field of vacuum metallurgical equipment, in particular to an electro-magnetic induction internal thermal type metallic magnesium vacuum reduction furnace which comprises a furnace body. A material basket (8) is arranged in the furnace body, and a central channel penetrating through the bottom face of the material basket (8) is formed in the center of the material basket (8). One or more heating cylinders (7) are concentrically arranged in the material basket (8). The material basket (8) and the heating cylinders (7) are filled with furnace burdens (9). A rectangular iron core is arranged in the furnace body. One long edge of the rectangular iron core penetrates through the central channel of the material basket (8), and a primary side coil (12) is wound around the other long edge of the rectangular iron core. The leading-out end of a copper winding of the primary side coil (12) is led out of the furnace through an insulated sealing device on the furnace body and is connected with a power source device. The electro-magnetic induction internal thermal type metallic magnesium vacuum reduction furnace is reasonable in design, distribution of a temperature field of the reduction furnace can be regulated, and heat transfer efficiency is high; the vacuum reduction furnace is used for high-vapor-pressure metallothermics production of magnesium, lithium, strontium, calcium and the like.

Description

technical field

[0001] The invention relates to the technical field of vacuum metallurgical equipment, in particular to an electromagnetic induction internal heating vacuum reduction furnace, which can be used for preparing magnesium, lithium, strontium, calcium and other high vapor pressure metals by thermal reduction. Background technique

[0002] Metals with high vapor pressure such as magnesium, lithium, strontium, and calcium can be prepared under vacuum conditions by thermal reduction. At present, in the field of metal magnesium production, the widely used reduction equipment is to directly heat the reduction tank made of heat-resistant alloy with gas or the like. This method is limited by the structure and material properties of the reduction tank, the reaction temperature is low, the heat transfer is slow, the energy consumption is high, and a large amount of expensive nickel-chromium alloy is consumed due to the oxidation of the reduction tank.
