[0002] The smelting process of aluminum alloy generally includes the following technological processes: furnace charging→melting (adding copper, zinc, silicon, etc.)→skimming slag→adding magnesium, beryllium, etc.→stirring→sampling→adjusting composition→stirring→refining→skimming slag→converter→refining modification and standing→casting. Furnace charging: correct furnace charging method is very important for reducing metal burning loss and shortening smelting time.

[0003] For reverberatory furnace, a layer of aluminum ingot is laid on the furnace bottom, and easy-to-burn loss material is put in, and then aluminum ingot is pressed on. The smelting point of the recycled material is relatively low, so it is melted first, and flows down to cover the easy-to-burn loss material below, thereby reducing the burning loss. Various furnace charges should be evenly and flatly distributed. Melting: the melting process and smelting speed have important influence on the quality of aluminum ingot.
