Single chamber furnaces generally require comparatively low investment costs. Furnace design is simple, rectangular or round, depending on individual application.
The rectangular furnace design with its front door across the full furnace width allows for maximum access during charging and skimming. Furnaces are designed either for hydraulic tilting (as casting furnace) or as stationary type.
Heating System: Cold air gas burners are common with casting furnaces. For lowest energy consumption (<600kWh/ton) regenerative burners are used, comprising honey comb type ceramic elements. Regulated flue gas flap or flue gas fan for adjusting the furnace atmosphere to a slightly positive pressure.
Accessories: Side wells or electromagnetic liquid metal pumps are fitted to the furnace wall. The electromagnetic stirrer enhances uniform temperature distribution and dissolution of alloying elements. If required, specific provisions are available for inserting gas lances into the melt.
Furnace capacity: 10 - 120 tons
Melting rate: 1 - 15 tons/hour
