Fuel-fired aluminum smelting furnace, that is, crucible smelting and holding furnace, is currently mainly used for smelting, casting and hot-dipping of non-ferrous metals such as aluminum, zinc, silver, lead, tin, and copper. Its main feature is the use of light diesel as fuel, clean and safe, making the workshop clean and tidy, easy to manage, low operating cost, high thermal efficiency, and very popular.

During the operation of the fuel oil melting aluminum furnace, some problems need to be paid attention to. Only in this way can the normal operation of the industrial furnace be guaranteed.

1. Before igniting the aluminum melting furnace, check whether the electrical equipment is normal. When an abnormal situation occurs, it should be dealt with in time.

2. When feeding the aluminum smelting furnace, some bulk materials should be placed on the bottom of the furnace to prevent collision and damage to the bottom of the furnace when placing the surface of the block materials.

3. In order to improve the smelting efficiency, enough charge should be placed in the shaft furnace, and the charge should be filled immediately throughout the smelting process to avoid wildfires.

Advance preparation before nozzle ignition.

1. Open all dampers of the device.

2. Start the centrifugal fan, open the nozzle baffle, purge the residual gas in the furnace, and close the nozzle baffle after a few minutes.

3. Start the oil pump, adjust the oil return pump and needle valve, the steam pressure in front of the nozzle is 0.1mpa.

4. When igniting, use the oil return pipe to inject enough oil, and put it in the proper position of the ignition hole in front of the nozzle after ignition.

5. When the fire detection alarm stops halfway, just click the "Alarm Reset" button to eliminate the alarm. Be sure to open the oven door before relighting. After confirming normal operation, close the furnace door to operate.
