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.
