1. The burner with low excess air coefficient is used, and the furnace atmosphere is a reducing atmosphere to reduce oxidation burning loss. The furnace oxygen sensor can be installed according to customers' needs to further accurately control the oxygen content in the furnace atmosphere, and the material burning loss is less than 1.2%.
2. With tower structure, the flue gas from the holding chamber and melting chamber is discharged from the feeding port to maximize the thermal efficiency of the furnace, and the heat consumption per ton of aluminum is less than 520000 kcal.
3. The electrical control system adopts imported components with high degree of automation and stable and reliable operation.
4. The protective tube for liquid aluminum measurement adopts the imported sheath of Hitachi metal Salong from Japan, and the service life is not less than 18 months. The ceramic sheathed thermocouple is used for melting and atmosphere measurement, and the service life of die castings is more than two years.
5. The feeder is controlled by frequency conversion speed regulation, which operates stably and reliably, and effectively protects the reducer and feeder.
