The combination Forge and Heat Treat furnace is designed specifically for the School Shop, where a single unit is required for heat treating or for hot bending, forming and forging operations. Sound in design, built of quality materials, these furnaces are capable of long and satisfactory service. Their compactness and flexibility are definite assets in the conservation of valuable floor space. The hearth size is 6 in. wide by 14½ in. deep. Overall inside depth between doors is 18 in. The front opening is 5 in. high by 7 in. wide; the rear opening is 5 in. by 7 in., with hinged, drop type doors which serve as work rests for end heating bars for forging. Long bars may be selective heated by opening both doors and positioning the area to be heated in the furnace chamber. The spiral firing principal used in the Spiro-Therm furnaces develop rapid, uniform temperatures throughout the heating chamber.

The FHT-57 is available in two styles. The standard model has spark ignition and a Combustion Safeguard Safety System. The AC model has a Temperature Control System in addition to the standard Safety System for accurate control of the furnace chamber for use in heat treating.
