For T6 with water quenching, T7 with air quenching,T5 with artificial aging, homogenizing, annealing and stress relieving, removal of sand from castings.
FURNACE TYPES:
Continuous roller hearth furnace.
Chain conveyor furnace.
Basketless direct part loading furnace.
MAIN CHARACTERISTICS:
Optimum fuel efficiency by pre-heating of incoming ingots/return material by outgoing exhaust gas
Special high impact resistance bricks for longer life
Gas Heating with Long Luminous low temperature flame burners operating with low excess oxygen
Immersion type burners in holding chamber for indirect heating to reduce oxidation of aluminum
Ingot / return material charging top by elevator mechanism
Safety features like low/high molten metal level, excess temperature of molten metal and exhaust gas, flame failure, gas/air low pressure, etc.
Computerized process monitoring
Fuel consumption 7,00,000 kCal/T of Al. during melting
Standard capacities: 100 kg/hr to 1500 kg/hr
QUENCH SYSTEM:
Options available for water, polymer or air quench.
