Aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed according to aluminum melting process. It can well meet the requirements of aluminum melting process.

It can also meet the requirements of strict alloy composition requirements, discontinuous production and large single furnace capacity, so as to reduce consumption, reduce burning loss, improve product quality, reduce labor intensity, improve working conditions and improve production efficiency. It is suitable for intermittent operation and smelting with more gold and reheating materials.

1. First check whether there are foreign matters in the lower aluminum melting furnace. If there is any foreign matter, it needs to be removed immediately. Check whether the feeding shaft is stuck due to excessive feeding during ignition. If so, just reduce the feeding during the ignition process.

2. Check whether the chimney outlet is unobstructed. If it is not unobstructed, clean up the ash in the chimney. Check whether there is ash accumulation between the lower pot and the furnace wall. If there is dust, it needs to be removed immediately. If the fire hole is blocked, sundries need to be removed.

3. Increase or decrease the air supply frequency of aluminum melting furnace and adjust the frequency to normal. Check the bridge of combustion chamber of aluminum melting furnace for coking and clean it.

4. If the whole current board fails, the current board needs to be repaired or replaced. If only the main switch is not turned off, just turn off the main switch. The control power adjustment potentiometer is damaged or short circuited and needs to be repaired immediately. 5. Inverter circuit board and inverter failure. Inverter power system fault, inverter pulse without 22V power supply.

6. In case of poor control of the frequency converter control board, it shall be repaired in time. When the small working angle is not adjusted properly, just adjust the working angle. The aluminum melting furnace is short circuited or grounded, and the voltage circuit can be short circuited at the output side.
