Engineering Heritage of the Inductotherm Melting Division

Inductotherm's melting division traces its origin to 1953 in Rancocas, New Jersey, USA, where founder Henry M. Rowan engineered the company's first coreless induction furnace in 1954. Following its first overseas plant opening in Australia in 1968 and ISO 9001 quality certification in the U.S.

since 1993 (currently ISO 9001:2015), Inductotherm Group (comprising 40 companies, 50 product lines, and 10 brands) has built over 41,000 induction melting and heating systems worldwide.

The Inductotherm Melting business line designs and manufactures coreless and channel induction furnaces for ferrous and non-ferrous metals, VIP SCR and IGBT solid-state power supplies from 15 kW to 24 MW, closed-loop DI water cooling stations, supervisory melt deck computers, and automated melt shop

robotics.

Heavy Steel Shell and Steel Frame Coreless Furnaces for Ferrous Foundries

For high-tonnage iron, steel, and bronze melt shops, Heavy Steel Shell coreless furnaces (350 kg to 100 metric tons capacity) deliver exceptional structural rigidity.

Heavy rolled-steel shells lined with laminated silicon-steel magnetic shunts contain the electromagnetic field and support the heavy-wall copper induction coil against electromagnetic forces, extending monolithic refractory lining life.

Available engineering options include hydraulic nose tilting, 33° back-slagging tilt, 12° back-tilt for drop-bottom charge buckets, hydraulic lining push-out cylinders, and close-capture MACT fume hoods.

In the 4 to 60 metric ton range, Steel Frame furnaces provide an open structural frame that simplifies routine inspection of magnetic shunts and cooling hoses.

Dura-Line, Small Steel Shell, Removable Crucible, and Precision Foundry Furnaces

For batch capacities between 25 kg and 3 metric tons, Dura-Line and Small-Capacity Steel Shell furnaces serve specialty iron, steel, and non-ferrous foundries.

Dura-Line furnaces utilize molded refractory or reinforced aluminum bodies paired with a patented Free Breathing coil design that allows the coil to expand smoothly with the refractory crucible.

To melt copper alloys, brass, bronze, aluminum, and precious metals without alloy cross-contamination, Push-Out and Lift-Swing removable crucible furnaces handle 50 to 300 kg of copper alloys or 20 to 100 kg of aluminum, often paired with packaged 10 to 15 kW Quick-Trak IGBT converters.

Precision lost-wax foundry shops rely on table-mounted Mini-Melt furnaces (2.5 to 25 kg) and variable-speed Rollover furnaces (2.5 to 50 kg).

Waterless Acutrak DEH Aluminum Furnaces and Hybrid Furnaces

For aluminum foundries seeking to eliminate cooling water from the melt deck, Acutrak DEH (Direct Electric Heat) crucible furnaces operate with forced air cooling across three standard models: 300 kg / 110 kW, 500 kg / 115 kW, and 1000 kg / 150 kW.

Eliminating water pumps, heat exchangers, and water-cooled leads simplifies installation and improves workplace safety.

For large foundries requiring both high cold-melting output and low-power holding, Hybrid furnaces (10 to 40 metric tons capacity) combine an upper coreless induction coil for rapid charge melting with a lower replaceable channel inductor for energy-efficient holding.

VIP SCR and VIP-I IGBT Power Supplies, Dual-Trak, and Multi-Switch

VIP (Variable Induction Power) solid-state converters span unit and modular outputs from 15 kW to 24 MW.

Available in series or parallel SCR topologies as well as hybrid VIP-I IGBT configurations, VIP power supplies automatically match load impedance variations from cold scrap to full liquid bath, drawing 100% rated power at high power factor.

Multi-output Dual-Trak, Tri-Trak, and Quad-Trak converters share power electronically between two, three, or four furnaces simultaneously without mechanical selector switches.

For multi-zone susceptors and graphite crucibles, the VIP Multi-Switch converter distributes up to 1,500 kW across up to 8 independent coil zones.

Melt-Manager Plus Automation, ARMS Robotics, and IRIS Laser Scanning

Melt-Manager, Melt-Manager Plus, and Meltminder 300 computer systems integrate VIP power control, charge weighing, automated cold-start refractory sintering schedules, and kWh/ton energy accounting with fiber-optic diagnostics.

Hazardous melt deck operations are automated by the ARMS (Automated Robotic Melt Shop) manipulator (30 to 500 kg payload), which handles slag removal, temperature dipping, sampling, bath ground probing, and trim additions.

Refractory wear is quantified by the IRIS long-range laser scanner, producing 3D thickness maps of the crucible wall in minutes.

OEM VIP Electrical Spare Parts and Heavy-Wall Copper Coils by IP# Code

Reliable operation of medium-frequency VIP cabinets requires factory-matched power semiconductors and control boards identified by Inductotherm IP# numbers.

Supplied spares include SCR thyristors (147-3176), rectifier diodes (147-3178-W), optical isolation modules (IP#170-7089), fiber-optic cables (#168-0862), control transformers (IP 163-0050-1, IP A09727GP4), panel voltmeters (153-3087), and phase-loss detectors (IP#170-9093 / 434-0147).

For furnace protection and water cooling circuits, we supply coil short-circuit detectors (#808331), manifold temperature sensors (149-0731S, 149-0755S), pump starter breakers (IP#148-0903), heavy-wall extruded copper induction coils with Dura-Shield insulation, magnetic shunts, and water-cooled

power leads.
