Induction melting system is a non-contact metal melting technology based on the principle of electromagnetic induction. It generates eddy currents in the metal raw materials in a closed container through high-frequency or medium frequency current, and heats them until the metal is melted. It is commonly used for the melting and refining of steel, non-ferrous metals and alloys. This process has become one of the important means of modern metal smelting due to its high efficiency, cleanliness, and controllability.
working principle
The key to an induction melting system lies in the induction coil, which forms a strong alternating magnetic field around the coil when high-frequency or medium frequency alternating current passes through it. Conductive metal raw materials placed in a magnetic field generate eddy currents due to electromagnetic induction effects, which generate heat through resistance and ultimately heat the metal to its melting point. Due to the self stirring effect formed by the metal melt pool itself, the melting process is uniform and efficient.
component
Induction coil: generates an alternating magnetic field to heat metal.
High frequency/medium frequency power supply: Supply the required AC power.
Cooling system: Keep the coil temperature moderate to prevent overheating.
Control system: Adjust power output and monitor the melting process.
Melting crucible: accommodates and holds the metal to be melted.
Key advantages
Efficient melting: rapid heating, high energy conversion efficiency.
Uniform melting: The stirring effect naturally formed in the molten pool results in uniform composition.
Clean and environmentally friendly: Closed systems reduce pollutant emissions.
Energy saving and consumption reduction: saves energy compared to traditional methods.
High degree of automation: easy to achieve continuous production and reduce labor demand.
