Fixed melting and holding furnace can perform combustion with four
types of fuel such as natural gas, liquefied petroleum gas, heavy
oil and diesel. The furnace body is fixed and non-movable. It has
straight furnace door indicating the door can be moved vertically
which is convenient and easy to use.
Slanting furnace door indicates the door does not lift or lower
vertically but it is shut tightly sorely by the weight of the
furnace door. This helps to reduce the heat energy lost. Fixed
melting and holding furnace mainly consists of steel external
shell, refractory lining, furnace door, lifting and clamping
mechanism of the furnace door and burner system.
The fixed melting and holding furnace can be equipped with
auxiliary equipment such as electromagnetic stirrer, molten
aluminum pump, charging car, etc. This model of furnace uses
regenerative burner system as burner which emits 90% and above of
the waste gas after heat exchanges through the regenerative bed.
Other waste gas emitted via conventional exhaust channel which
