The most energy-efficient induction melting furnace available. IGBT technology delivers 10–20% lower electricity costs per ton — with Infineon modules, automatic frequency tracking, and full PLC control.
At $0.08–0.15/kWh, an older furnace running 580–650 kWh per ton of steel adds up fast. IGBT technology brings this down to 480–560 kWh — saving tens of thousands annually at high production volumes.
A furnace failure mid-shift can mean hours of lost production, rushed repairs, and delayed deliveries. Customers need a furnace with comprehensive protection circuits that prevent failures before they happen.
Older SCR-based systems drag power factor down to 0.75–0.85, triggering reactive power charges from your utility. IGBT technology achieves 0.95+ power factor, eliminating these extra costs entirely.
Generic components are difficult to source. YuRun builds exclusively with Infineon and Fuji IGBT modules — globally available from authorized distributors — so repairs take hours, not weeks.
The YuRun IGBT Induction Melting Furnace is a complete melting system combining a heavy-duty furnace body, IGBT medium frequency power supply, closed-loop water cooling system, and PLC control panel — all engineered to work together as one integrated unit. Available from 0.5 tons to 30 tons capacity for iron, steel, copper, aluminum, and non-ferrous metals.
The core advantage of IGBT technology is efficiency. Where older SCR systems waste energy through poor power factor and slower frequency tracking, IGBT inverters maintain 95%+ conversion efficiency and automatically track the resonant frequency as metal transitions from solid to liquid. This means consistent, maximum power delivery at every stage of the melt — and a measurable reduction in kWh per ton of metal produced.
IGBT inverters achieve ≥95% conversion efficiency versus 85–88% for SCR systems. In real production, this means 480–560 kWh/ton for steel — a direct, measurable reduction in your electricity bill from day one.
As metal melts and load impedance changes, the IGBT inverter automatically adjusts operating frequency (100–2500Hz) to stay at resonance — maintaining maximum power transfer from cold charge to pouring temperature without any operator adjustment.
Overcurrent, overvoltage, under-voltage, overtemperature, water-flow loss, phase-loss, and short-circuit protection — all built into the IGBT gate driver circuits. Response time in microseconds, before damage can occur.
Every YuRun IGBT furnace system includes or is compatible with our closed-loop cooling system. Treated soft water, per-circuit flow sensors, automatic temperature control, and furnace interlock — protecting your IGBT modules and coil investment.
Siemens S7 PLC records every melt cycle: power, temperature, duration, energy consumed, and fault events. Export production data via USB for ERP integration, yield analysis, or remote diagnosis by YuRun engineers via TeamViewer.
