Cold crucible induction shell melting (ISM)

ISM refers to the production process of using a segmented water-cooled copper crucible to melt and cast metal in a cold crucible induction shell suspension melting furnace under vacuum or protective atmosphere, which avoids the pollution caused by various ceramic crucibles on the melted metal. When the induction coil is energized, a strong magnetic field can be formed inside the cold crucible to keep the melted metal in a semi suspended or fully suspended melting state, so ISM is also known as suspension melting. As a new type of smelting technology in the 21st century, ISM has its unique advantages and broader application prospects:

1. Advantages of ISM:

1. Able to melt high melting point metal materials;

Due to the absence of impurities from the crucible, ultra-high purity metal materials and active metal materials can be melted;

Due to strong electromagnetic stirring, alloys with uniform composition and structure can be produced, which are not affected by the specific gravity of the melted material composition;

4. Shorten the melting time to achieve rapid melting;

The damage to 5 pairs of crucibles is relatively small, and water-cooled copper crucibles have a good service life;

There is no direct contact between the cold state crucible and the molten metal liquid, which reduces the cooling load of the crucible, reduces heat loss, and reduces energy consumption;

7. Metal melt is easily poured out of the crucible in a non-contact state;

8 can melt any shape of additive material, such as block, powder, flake, chip, sponge, etc.

Application of ISM:

1. Melting of active metals, high-purity materials, refractory alloys, semiconductor materials, and radioactive materials.

Soft contact forming of materials such as steel, aluminum, and their alloys.

3 provides important means for the development of aviation and aerospace industry, national defense and military industry, electronic industry, metallurgical industry, and mechanical industry, and has broad application space in both military and civilian fields.
