Induction melting systems for foundries

Material, usable capacity, melt rate, charge sequence, holding time and alloy changes define the furnace concept. Coreless furnaces provide flexibility, while channel furnaces are well suited to continuous holding and specific production duties.

The system design includes grid connection, transformer, converter frequency, capacitor bank, power conductors, cooling and protection.

• Ferrous and non-ferrous metals
• Melting and holding
• New plants and retrofit

Coil or inductor geometry, coupling, frequency and power density affect bath movement, melt time and component loading. Electrical matching must keep currents and voltages within safe limits across the operating range.

Cooling circuits and protection functions are engineered from actual losses and operating conditions.

• Load characteristic and resonance
• Capacitor bank and power cables
• Cooling and safety monitoring

Existing melting systems can be upgraded with modern converter technology, PLC/HMI, measurement and optimised compensation.

The objective is stable melt rate, low specific energy demand, repeatable batches and high availability.

• Measurement and diagnosis
• Converter and control retrofit
• Melt rate and kWh/t optimisation
