High Thermal Efficiency and Precise Temperature Control Aluminum
Holding Furnace
1. Product Description
Immersed aluminum alloy electric holding furnace is mainly used for
the insulation of non-ferrous metal solutions. It has high
requirements
for die-casting process and low energy consumption equipment is
preferred. At present, die-casting foundries are looking for
breakthroughs in how to improve production efficiency, optimize
energy consumption to the greatest extent, and implement continuous
transformation.Direct internal heating of molten aluminum has high
thermal efficiency, does not produce oxides, has high temperature
control accuracy of molten aluminum, and its energy consumption
is more than 60% lower than that of ordinary radiation heating
furnaces.
Heating elements imported from France, EuropeThis Industrial
Immersion
Holding Furnace has been upgraded and renovated based on the
previous
generation of holding furnaces, with optimized structure. After
being stabilized
through actual use, a new generation of holding furnaces has been
launched.
2.Advantages of the new generation of immersion holding furnaces:
● No aluminum liquid burnout, ensuring high quality of aluminum
liquid;
● Ultra-low energy consumption cost, heating source close to 100%
thermal efficiency;
● Precise temperature control accuracy (±2 ℃);
● Intermittent shutdown can be achieved, easy to operate;
● Replacing the heating tube is more convenient and can be done
after basic on-site training;
● Patented furnace structure design ensures longer furnace life;
● Dual heating system, failure of a single system will not affect
production;
● Compact design structure, small space occupied;
● All exposed parts are equipped with protective covers or shields
to
ensure the safety of personnel and equipment;
● The LED digital tube display screen outside the electric cabinet
can
check the real-time temperature of the aluminum liquid from a
distance;
● The control circuit is equipped with an isolation transformer to
ensure
the safety of operators and save users' wiring costs.

Siemens and Schneider are mainly used. At the same time, the
temperature
control implements aluminum temperature, and the internal
temperature of the
heater is monitored at the same time to prevent over-temperature
protection.
