Shell type vacuum induction melting furnace
Vacuum induction melting (VIM) is an advanced metal smelting process that is widely used in the industry. VIM is a type of furnace used to smelt a variety of metals and alloys at very high temperatures in a vacuum environment. The shell type vacuum induction melting furnace is one of the most popular types of VIM furnaces used in industrial applications today.
The shell type vacuum induction melting furnace consists of a sealed steel shell that allows for high temperatures generated inside to melt metals and alloys. The induction heating system of the furnace works by creating an alternating magnetic field through the inductor coils to melt the metal along with a vacuum atmosphere to minimize oxidation. The process is capable of melting any ferrous or non-ferrous material including iron, steel, aluminum, brass, bronze, and other alloys.
This type of furnace generally consists of an induction melting coil, a core assembly, a vacuum chamber and filter, and a mechanism for loading the materials to be melted. The melt chamber is generally made of electric-resistant or refractory material and is welded to the shell/dome. The induction coils are then placed on the inner wall of the shell/dome and are connected to the core assembly which contains the power supply.
The core assembly allows for precise control of the dense magnetic field, allowing for higher efficiencies in the melting process. In order for the furnace to create the necessary vacuum environment to facilitate the melting process, the chamber is equipped with an extraction pump, which works to remove air, oxides, and other elements from the atmosphere. This makes the process even more efficient and versatile.
The shell vacuum induction melting furnace is an ideal choice for advanced materials such as superalloys and intermetallic compounds with high melting points such as stainless steel, titanium, and nickel based alloys. The furnace is also excellent for the production of small batches of high quality and intricate parts.
The high levels of control and low loss of material makes the shell type vacuum induction melting furnace an efficient and cost-effective choice for many industries. This type of furnace is also very safe to use, as the environment and the materials inside are completely contained and secure.
As the technology continues to advance, the shell type vacuum induction melting furnace will become more common in foundries and factories around the world. It is highly reliable and efficient, making it an ideal choice for industrial and other applications for melting metals, alloys, and other materials.
