Magnetic levitation in induction furnaces to reduce contaminants

Cold crucible induction furnaces (CCIF) are widely used in the melting of reactive and pure metals, as they virtually eliminate contamination. During melting, the induction furnace has to simultaneously melt and levitate the molten load in a process where the load’s phase, shape and properties are in flux. To design a cold crucible induction furnace that satisfy these conditions, requires the consideration of the complex interaction of electromagnetic, thermal, hydrostatic and electro-dynamic principles.

Electromagnetic simulation software is essential to optimize several key parameters:

• Generate electromagnetic forces to control the molten load in order to reduce contact with the crucible walls
• Evaluate the electrical efficiency and load utilization
• Dramatically reduce the contamination of the load
• Reduce utility costs
