Coreless Induction Metal Melting Furnace with Steel Shell
Heavy-Duty Melting for Foundries & Steel Mills
The Topyro steel shell induction melting furnace is a heavy-duty coreless induction furnace engineered for continuous, high-volume melting of steel, cast iron, copper, and aluminum. Its steel shell is combined with a laminated silicon-steel magnetic yoke that contains and directs the magnetic field into the charge — delivering higher melting efficiency, lower stray field loss, and greater structural rigidity than aluminum shell designs.
Built on Topyro's IGBT/SCR medium-frequency power platform, the furnace achieves temperatures up to 2000°C with fast melting cycles and precise temperature control. Capacities range from 0.5T to 30T, making it the preferred choice for foundries, steel plants, and non-ferrous melting operations that run around the clock.
As a factory-direct manufacturer, we handle engineering, fabrication, installation, commissioning, and operator training — you receive a working melting furnace, not just a machine.
Key Features of the Steel Shell Induction Melting Furnace
- Magnetic yoke design — laminated silicon-steel yokes contain the magnetic field, directing energy into the charge for up to 20% higher efficiency than yokeless designs.
- Heavy-duty steel shell — maximum structural rigidity and safety, built for 24/7 continuous production.
- IGBT/SCR medium-frequency power supply — high power factor, fast melting, and precise temperature control with reduced grid impact.
- Electromagnetic stirring — uniform bath temperature and composition for consistent casting quality.
- Hydraulic tilting system — smooth, controlled pouring with manual backup for safety.
- CE-certified & export-ready — machinery test reports and full documentation provided with every shipment.
