Composition of melting furnaces

Melting furnace is a new type of energy-saving melting furnace developed on the basis of aluminium melting process. It is mainly used for smelting and holding of aluminium ingots. It can well meet the aluminium smelting process. The furnace body consists of melting furnace, crucible, heating element, lid lifting mechanism, electrical automatic temperature control system and so on. The furnace shell is welded into a cylindrical shape by section steel and steel plate. There is a hole in the lower part of the front end of the furnace body for the crucible to crack and leak due to corrosion and oxidation. The melt in the crucible can flow out of the furnace through this hole without damaging the working chamber. Let’s take a look at the structural features of the melting furnace.

There is a hole in the lower part of the front end of the furnace body for the crucible to crack and leak due to corrosion and oxidation. The melt in the crucible can flow out of the furnace through this hole without damaging the working chamber.

1, the furnace body. 8mm steel plate and steel section welded into a box-shaped whole, that is, the furnace body, the furnace body has an air inlet, feed port, aluminium nozzle, aluminium nozzle, slag outlet and support frame Auxiliary system. The melting furnace insulation is made of asbestos sheet enclosure material in the furnace shell. The furnace lining consists of refractory bricks and carbon and silicon brick mortar to form the melting chamber and preservation room with corresponding entrances and exits.

2、Combustion system. It consists of fuel tank, fuel pump, burner and pipe. It is divided into two groups, which are placed in the melting room and preservation room respectively.

3、Degassing refining and densification system. In the melting furnace inlet on the other side of the set degassing refining metamorphosis room, with pure nitrogen pressurised into the aluminium liquid, configure the blowing flow, the use of adjustable graphite rotor lower end of the uniform dispersion of aluminium liquid. Aluminium liquid nitrogen and flux in the aluminium liquid make the aluminium liquid to achieve the effect of degassing, deslagging and refining, and can be modified in the refining room.

4、Feeding system. Mechanical or manual automatic feeding is available to make the support material enter the melting chamber.

5、Exhaust system. A 300mm exhaust pipe is installed at the upper corner of the back of the furnace to discharge the smoke to the outdoor.

6、Temperature measurement system. The temperature measuring thermocouple of the melting furnace is connected with the automatic temperature control equipment to automatically control the temperature of each temperature measuring point.
