Adopting Aluminium alloy or pure aluminium as shell.
It is light, low density.
Low strength, can not resist high temperature.(It is mainly used in
medium and low-temperature processes (such as aluminum smelting and
heating of non-ferrous metals).
Good heat conduction, Heat pass ratio is high.(The shell conducts
heat quickly, so attention should be paid to the heat dissipation
design to avoid structural deformation due to overheating.)
It has good thermal conductivity, fast heating speed and high
energy utilization rate, making it suitable for rapid heating or
short-term operations. But if heat faster, insufficient heat
preservation measures, may lead to increase energy consumption.
The surface of aluminum is prone to form a dense oxide film
(Al₂O₃), which is naturally resistant to corrosion and suitable for
humid, acidic and alkaline environments (such as in the chemical
and food processing industries).
The initial cost is relatively low (aluminum is cheaper than
steel), but the shell is prone to deformation due to impact or high
temperature, and the structural stability needs to be checked
regularly. Maintenance is relatively simple, focus on cooling
system (such as fan, cooling line) is obstructed.
Aluminum shell furnace applicable scenario
non-ferrous metal processing: aluminum, copper alloy smelting,
casting of aluminium alloy heat. Food and medicine: baking, drying,
(resisting corrosion and temperature controlled required).
Electronic and light industry, electronic components, plastic
processing, (such as heat furnace to match injection molding
machine matching ).
1. Aluminium furnace shell is made by Aluminium. The outside shell
is not so strong, after long time service, it is prone to
deformation.
2. Aluminium furnace structure is simple. Mainly by aluminium
shell, induction coil. Protective performance is poor. There is
security thread. Without magnetic yoke, power loss is big. And the
magnetic field generate by the furnace is harmful for operator.
3. The efficient is almost same with steel shell furnace.
4. The cost is lower.
