China 20 Ton Regenerative Fixed Tilting Type Aluminium Melting Furnace

Technology description:
10T regenerative Smelting furnace adopted flat topping and square structure. Aluminum ingot is the main input material. According to the requirement of technology, some solid matter (such as aluminum ingot head or tail) can be inputted appropriately. This furnace is applied with two sets of regenerative burner that to ensure the heating-up and heating-hold of aluminum liquid before casting. The furnace is with vertical door, and the size is comparatively large so that it is good for inputting material, refining aluminum liquid, slag-off and other operation.
