Abstract
A furnace for melting and holding aluminum materials, the furnace being characterized in that the furnace comprises: a pre-heating tower for pre-heating aluminum blocks, a melting crucible furnace which receives a supply of aluminum blocks from the pre-heating tower at a position immediately under the pre-heating tower, and a holding crucible furnace which receives a continuous supply of molten aluminum from the melting crucible furnace at a position side-by-side with the melting crucible furnace, and that an exhaust gas resulting from combustion in the melting crucible furnace can be supplied to the inside of the pre-heating tower as an ascending current for heat exchange with aluminum blocks, the furnace being capable of continuous melting and energy savings.
