Hot Chamber Furnace Systems

Hot Chamber Melting Solutions2

Contoured Element Design for Hot Chamber Furnaces

Hot Chamber Melting Solutions3

Advantage of Contoured Element Design

Up to 35% more kW Floor heating for more direct heat transfer crucibleEven heat distribution to crucible results in longer lifeConverts solid ingot into a liquid much faster

Hot Chamber Melting Solutions4

Thermal Heating System

Insulating modules also supports heating system EES Ceramic Modular replaceable insulationSuperior heat retention compared to brick and board insulationLower furnace cold face temperatureHeavy gage solid rod over bend element wire

Hot Chamber Melting Solutions5

SSR Power Controls

Dramatically increase element lifeMinimizing temperature extremesNo replacing of mechanical contactors Operates seamlessly with Feed Forward PID® Systems Board

Hot Chamber Melting Solutions6

Contoured Design Applications

Hot or Cold Chamber Furnaces1 TO 3 Heating Zones40 to 800 kWEES Rod over bend element designUp to 35% more kW 3 to 5 years element life

Hot Chamber Melting Solutions7

Crucible Forward Furnace DesignNo heating elements at the front of furnace, additional floor elements supply required heatAir space for heat circulationA Shorter nozzle can be usedCounters gooseneck heat sink effect

Hot Chamber Melting Solutions8

Castable Refractory Floor

Deeper furnace box Thicker refractory floorSilica free refractoryOnce refractory floor is super heated it acts as a heat spreading “hot plate” distributing heat evenly along crucible bottom even when heat is not cyclingPrevents spikes in molten bath temperature

Hot Chamber Melting Solutions9

Feed Forward PID Heating Controls

Takes over PID as soon as production mode is selected. Reacts faster and ahead of slow acting temperature controllers typically supplied to control furnaceReduces temperature swings at start of productionFully adjustable to suit small or large melt rate Boosts furnace melt rate by up to 30%Minimize power consumption per Kilogram of magnesium melted
