The ALUSWIRLER® system is designed for continuous melting of aluminium chips, by submersion in a hot molten metal vortex.
The ALUSWIRLER® is the hearth of the system. The aluminium chips are melted because their submersion into the liquid metal and the quick heat transfer from the hot molten metal. The vortex is generated by a mechanical pump electrically driven.
The ALUSWIRLER® chamber is a side well attached to the main furnace chamber, linked by communication channels, which direct the flow of molten metal generated by the mechanical pump.
The impeller, its housing and the vortex chamber are ceramic pre-cast shapes,
easily replaceable. They are located into the refractory living of the side well,
becoming so the ALUSWIRLER® chamber.
The impeller rotation produces a high flow of molten metal, that downwards becomes a vortex of hot liquid metal, point where the pretreated and dried aluminium chips are charged for its melting, being submerged nearly instantaneously. The melting process is so quick that all the chips are melted before they can reach the main chamber of the furnace.
