Profitably Casting Your Bottom Line!

Dry Hearth (Gas, Oil or Propane) Furnaces

Schaefer Furnace

We design Dry Hearth furnaces to melt aluminum ingot and large billet; no gassing or contamination by the lining means that metal purity remains high. Impurities and the oxide skin stay on the hearth as only molten aluminum enters the hold zone.

Case Study:

  • Low fuel consumption – a modest 2.0 CF of gas per pound (504 kcal/0.4536 kg) of melted aluminum, thanks to the highly efficient radiant roof; this number drops even further with high momentum burners. A two-zone control offers the closest temperature control possible.
  • Easy to Clean – charge and clean-out doors are tangent with the side walls for quick cleaning access. A double hinged or full width clean-out door provides easy and complete access to the hold zone.


This versatile furnace meets the needs of a variety of metal casters, high and low pressure die casters, and permanent mold, sand, investment and lost foam foundries around the world.
