Are you looking for a vacuum induction melting furnace for sale? First of all, we need to know the history of the vacuum induction melting furnace. The world's first vacuum induction furnace was born in Germany in 1917, used to melt aircraft and rocket engines. A vacuum induction melting furnace is one of the most widely used equipment in the field of vacuum metallurgy. It has been proven that a considerable proportion of the alloys and special steels required for aerospace, missiles, rockets, atomic energy equipment, and electronic industries are produced using vacuum induction melting furnaces. For example, when nickel base, cobalt base and iron base superalloys are smelted by vacuum induction melting furnace process, their hot working and mechanical properties are significantly improved.
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 using vacuum induction melting furnaces to ensure material performance and quality. In addition, with the development of secondary remelting technology, another use of vacuum induction melting furnaces is to provide high-quality consumable electrodes for vacuum consumable arc furnaces or electro slag remelting furnaces, as well as to produce parent alloys for precision casting.
As is well known, the entire process of metal melting, refining, and alloying in the vacuum induction melting furnace process is carried out in a vacuum state, thus avoiding pollution caused by the interaction of the same gas phase. Secondly, under vacuum conditions, carbon has a strong deoxygenation ability, and its deoxygenation product CO is continuously pumped out of the system, overcoming the pollution problem of deoxygenation using metal deoxidizers.
The vacuum induction melting furnace process can accurately control the chemical composition of alloys and can control the active elements Al, Ti, B, Zr, etc. with a strong affinity for oxygen and nitrogen within a small range. Low melting point volatile metal impurities such as Pb, Bi, Sn, Sb, etc. can be evaporated and removed, which plays an important role in improving material performance. The strong induction stirring effect can accelerate the reaction speed, which is effective in achieving uniform temperature and chemical composition in the molten pool.
The rapid development of the vacuum induction melting process is closely related to the superalloy materials required by the aerospace industry, such as those required by aerospace, missiles, rockets, atomic energy, and other equipment. The maximum working temperature of high-temperature alloys produced without the vacuum melting method is generally only 750-810 ℃; The high-temperature alloy produced by the vacuum melting method can reach a maximum working temperature of 980-1090 ℃.
This is mainly due to the use of vacuum induction melting furnace to melt nickel-based, iron-based, and cobalt-based high-temperature alloys, which reduces the gap elements O2, N2, H2, and can completely remove non-metallic inclusions, as well as remove low melting point harmful metal impurities such as Pb, Bi, Sb, Cu, Sn, Te, etc.
The equipment of a vacuum induction melting furnace mainly consists of a furnace shell, inductor, crucible, tilting furnace mechanism, ingot mold mechanism, power supply device, and water cooling system. The furnace shell is equipped with devices for observation, temperature measurement, feeding, sampling, and compacting. The furnace is equipped with a vacuum system, power supply system, and control system outside. There are two types of vacuum induction melting furnaces: intermittent and semi-continuous, which can be made into vertical or horizontal types.
An important issue to consider in the structural design of a vacuum induction melting furnace is to avoid vacuum discharge. Therefore, all charged bodies inside the furnace shell need to undergo insulation treatment, and the inductor should be structurally free of sharp corners, burrs, and edges.
