Vacuum melting of metal

Are you interested in the technology of vacuum melting of metals from the supplier company AvecGlob? Here you will find interesting information on this topic /

Principle of vacuum melting

This is the metallurgical process of melting metals under vacuum conditions using electromagnetic induction. It is used for melting metals and alloys of extremely high purity. Metals are processed in a vacuum induction furnace, inside which temperatures up to 1800 ° C or more are reached.

The main equipment of shops and departments of vacuum melting of metals are vacuum induction melting furnaces and foundry furnaces.

Casting furnaces and vacuum induction melting furnaces melt pure metals and alloys that can not be melted in air because of their affinity for oxygen and nitrogen. Depending on the material, melting is carried out in ceramic, graphite or clay-graphite crucibles.

Supplier — AvekGlob company — offers at affordable prices from the manufacturer various metals and high purity alloys in a wide range of cross sections and weights. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Applications of the vacuum melting process

A positive feature of the technology is a high degree of metal purification from possible harmful impurities and gases. The latter is achieved by vacuum degassing of oxygen. This process reduces the gas content, especially hydrogen and carbon, and also reduces the percentage of non-metallic inclusions. Vacuum degassing is also used if it is required to reduce the percentage of carbon in a metal or alloy.

Sometimes vacuum melting uses refractory compounds such as aluminum nitride or silicon carbide. The metal is heated using medium-frequency induction, which has two important advantages: a reduction in the reactions between the melt and the crucible and a good homogenization of the melt. Induction melting technology is also used for cleaning metals and alloys (degassing, removal of slags).

Typical materials that are subjected to vacuum melting are aluminum, tin, zirconium, chromium-molybdenum alloys, titanium and its alloys with silicon, aluminum alloys with vanadium, silicon, niobium and other rare metals.

Supplier — AvekGlob Company — offers to purchase various metals and alloys in any quantity and range of profiles obtained by vacuum melting technology. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
