The automated aluminum melting cell manufactured by Thermtronix consists of three RS-Series Electric Resistance Furnaces, sized to meet the particular application, on a motorized steel turntable.
Products include ductile iron pipe and fittings, ductile iron castings, fire hydrants, valves, fire truck pumps, centrifugally cast steel tubes, static steel castings, fabricated assemblies, Electric Resistance Welded (ERW) steel pipe and spiral-welded steel pipe.
Those materials lose all electric resistance at temperatures that are extremely cold yet much higher than the operating temperatures of ordinary superconductors.
