ALGM type electric crucible furnace
The aluminum alloy melting and aluminum liquid outlet of ALGM type electric crucible furnace are implemented at the same in the crucible. As such, the aluminum aloy should be fed in a proper quantity by many times with a small quantity for each time. The outer shell applies 6mm rolled iron plate with lining which is composed of low heat transfer mullite insulating brick, high purity cotton insulation and heat insulation coating in a sequence of heat conduction performance. The heating component is fixed on the holding brick. There is a leak hole on the furnace to avoid the leaked aluminum liquid damaging the component after the crucible is broken. The furnace has a rotary cover used to seal the crucible mouth for holding with less energy consumption.
Electric heating system
There are two positions on the furnace used to measure the temperature of aluminum liquid and furnace chamber respectively, controlled by two output temper ature controllers with different proportions and able to meet the requirement on the temperature for the aluminum liquid in various cases and reflect the real situation of the furnace. It also has a leakage alarm detector which can alarm and close the heater to avoid the leak of aluminum liquid due to broken crucible.
1. Temperature measuring system: We adopt the imported temperature sensor to measure the current temperature of the furnace chamber and aluminum liquid accurately.
2、Heating system: This furnace is equipped with 5 groups of W type heating tapes inside it.
