What is Vacuum Induction Melting Furnace? 

 

The world’s first Vacuum Induction Melting Furnace was built in Germany in 1917 to melt the engines of aircraft and rocket engines. The vacuum induction furnace is one of the most widely used machines in the field of vacuum metallurgy. It has been proved that a considerable proportion of the alloys and special steels required by the aerospace, missile, rocket, atomic energy equipment, and electronics industries are produced by vacuum induction melting furnaces. Almost all stainless steel, heat-resistant steel, ultra-high-strength steel, tool steel, bearing steel, as well as magnetic materials, elastic alloys, expansion alloys, etc. are melted by vacuum induction melting furnace to ensure the material performance and quality. In addition, with the development of the secondary remelting process, another use of vacuum induction melting furnace is for vacuum self-consuming electric arc furnace or electro slag remelting furnace to provide high-quality self-consuming electrodes, as well as the production of master alloy for precision casting.

As we all know, the vacuum induction melting furnace process, the whole process of melting, refining, and alloying of metals is carried out in a vacuum state, thus avoiding the same gas-phase interaction and pollution. Secondly, in a vacuum, carbon has a strong deoxidation ability, and its deoxidation product CO is constantly pumped out of the system, overcoming the pollution problem of metal deoxidizer deoxidation.
