In recent years, the magnetic levitation smelting technology has been developed rapidly, and it has been applied in the research and production of titanium and titanium alloys.
Magnetic suspension smelting technology is a smelting method that uses high-frequency or intermediate-frequency alternating magnetic fields to form electromagnetic forces that offset gravity during metal or non-metal eddy current smelting, so that the melt is suspended and out of contact with the inner wall of the crucible to prevent crucible contamination. The smelting method is a comprehensive metallurgical technology integrating electromagnetics, fluidics, thermodynamics, physical chemistry and metallurgy. Mainly used to prepare high melting point, high purity and extremely active metal or non-metal materials, various high purity materials, high temperature materials, high entropy alloys, refractory metal ingots, blocks, bars, castings, etc., furnaces The temperature can be controlled within 3600℃, and the weight of the single furnace smelted metal is 0.5 to 200Kg or more.
This process technology can obtain ultra-high purity metal ingots, alloying and smelting of various metals to obtain alloy billets with uniform composition. It can be matched with casting equipment to realize the casting of high-purity metals or alloys. For example, using tilt casting, bottom casting, suction casting and other process equipment to produce metal or non-metal casting products of various sizes. The alloy composition produced by this process technology has high uniformity, and multi-chamber technology can be adopted to improve production efficiency and realize industrialized mass production.
