Heavy Steel Shell Furnaces

These furnaces combine the exceptional strength of a rugged steel shell with easy accessibility making them ideal for melting a wide range of metals.

Excellent durability

Due to our superior design and technological expertise, Inductotherm Heavy Steel Shell Furnaces are the most durable furnaces on the market today. They are more efficient, more productive, quieter and easier to maintain than competitive furnaces. Heavy steel shell furnaces are designed to be stronger than frame-based designs.

Exceptional performance

They are also significantly quieter, thanks to our solid steel shell’s sound-deadening characteristics. For installations requiring even quieter performance, sound-absorbent insulation can be added inside the shell. Large access panels on every Heavy Steel Shell Furnace are constructed from heavy steel to protect the coil during furnace operation.

Variety of options to suit your requirements

Heavy Steel Shell Furnaces can be used with our back-slagging feature, push-out lining systems, weigh frames, pit guards and more. They can be retrofitted with a variety of fume collectors and hoods. This includes our latest Vortex extraction hood that can help you comply with the strictest air pollution requirements, such as MACT (Maximum Achievable Control Technology) standards. Inductotherm’s Heavy Steel Shell Furnaces are ideal for melting all metals and silicon.

Heavy Steel Shell Furnaces are also available with an optional wide-bodied design which have a significantly larger bath diameter and furnace opening and can be ideal depending on your application. They offer additional benefits such as lower installation costs, lower scrap costs and better access to slag.

Safety Options

Safety Options and Retrofits are critical for guarding your equipment against possible failures. To improve each units overall efficiency and safety, Inductotherm provides options that can be retrofitted as needed to provide you with the most advanced equipment without replacing entire units, which include:

  • Close capture furnace fume covers assist our customers with MACT compliance. We offer a full range of covers that can be retrofitted to almost all large and small Inductotherm coreless induction furnaces, new and existing. These covers are designed to effectively collect smoke, dust and airborne pollutants during all phases of furnace operation. The Vortex™ extraction hood is a high velocity hood that offers many benefits including less escaped fumes and better access. 
  • Lining Push-Out Systems for furnaces greatly reduce the time and labor for refractory lining changes by using a large movable plug to push out the entire lining in just minutes for easy disposal. It reduces exposure of foundry personnel to refractory dust which improves working conditions along with profitability and productivity.
  • Back slagging permits the furnace to tilt at a 33 degree angle toward the rear. Tilting the furnace provides sufficient space above the deck for a portable hopper which will make it easy for the slag to be pulled through the rear spout into the hopper.
  • Back tilting is offered where approximately 12 degree back tilt angle is achieved for slag removal, utilizing a lower cost tilt frame with extended cylinder construction. Nose tilting shifts the furnace rotation point forward, increasing pouring accuracy where small pours or a controlled pour stream is required.
