Electric Furnace for Sand Casting of Aluminum and Steel

The Foundry Electric Heating Furnace is an industrial heating system powered entirely by electricity, engineered specifically for foundry applications—including melting (aluminum, copper, zinc alloys), molten iron/steel holding, ladle preheating, core drying, and die warming. With zero emissions, high thermal efficiency (≥85%), precise temperature control (±3°C), and quiet operation, it has become the preferred alternative to gas or coal-fired furnaces in green and smart foundries—especially where environmental compliance, energy savings, and process stability are critical.

Eco-Friendly & Zero Emissions
No combustion—zero CO, NOx, SO2, or particulate emissions. Fully compliant with GB 39726 and EU environmental regulations, supporting carbon neutrality goals.

High Thermal Efficiency & Energy Savings
Direct electric-to-heat conversion achieves 85–95% efficiency (vs. 40–60% for gas). With smart power modulation and optional heat recovery, total energy use drops by 20–35%.

Precise Temperature Control
PID + SCR closed-loop control maintains ±3°C stability—ensuring homogeneous melt chemistry, minimizing oxidation, and improving casting yield.

Safe & Low Maintenance
No open flame or gas lines—intrinsically safe. Modular heating elements (MoSi rods, resistance bands, induction coils) allow hot-swap replacement. MTBF >50,000 hours.

Smart & Industry 4.0 Ready
Standard PLC + HMI with recipe management, energy logging, and alarms. Ethernet/Profinet interface enables MES integration for remote monitoring and traceability.

Auto Parts Foundry: Aluminum wheel melting + automatic ladle preheating
Ductile Iron Pipe Plant: Iron holding furnace at 1450–1500°C synchronized with molding line
Investment Casting Shop: Shell core dryer with multi-zone temp control (200–350°C)
Heavy Steel Foundry: Stress-relief annealing of large castings in car-bottom furnace
