Aluminum alloy melting furnace is an indispensable and important equipment in the aluminum products industry. It can melt aluminum and adjust the alloy composition, and can provide high-quality raw materials for subsequent die-casting processes.

[0003] In the prior art, the aluminum ingot is melted by direct heating. At this time, the aluminum ingot is affected by the high-temperature flame and strong airflow, resulting in greater oxidation and burning loss, and a large amount of high-temperature smoke will be generated after heating, which causes high pollution and large heat energy loss; or the aluminum ingot in the inner liner is melted by heating the inner liner.
