Energy-Saving VIM Vacuum Induction Melting Furnace - Top China Supplier & Factory for High-Value Alloys

Vacuum Induction Melting (VIM) is an advanced metal melting process that utilizes electromagnetic induction under vacuum conditions, making it ideal for producing high-value alloys. In this method, an induction furnace equipped with a refractory-lined crucible and surrounded by an induction coil is located within a controlled vacuum chamber. This setup ensures optimal melting of metals with precision, as the furnace is connected to a power source tuned to the specific frequency required for the furnace size and the materials being melted.

During the VIM process, material is charged into the induction furnace under vacuum, and power is applied to initiate melting. Additional charges can be added to achieve the desired volume of molten metal. The refinement of the molten metal occurs under vacuum, where its chemistry is meticulously adjusted to achieve the precise specifications needed. Various techniques such as chemical reaction, disassociation, flotation, and volatilization are employed to remove impurities. When the ideal melt chemistry is reached, a preheated tundish is inserted through a specialized valve system into the hot tundish. This refractory tundish is positioned in front of the induction furnace, allowing the molten metal to be poured seamlessly into molds.

VIM is essential for producing superalloys, stainless steels, magnetic and battery alloys, electronic alloys, and other high-performance materials. As a leading supplier and factory in China, we specialize in delivering top-notch VIM services to meet the demanding needs of the metal industry.
