Boost the efficiency of your gas-fired aluminum
Jul 01 1998 · Since the furnace must provide another 12 000 btu/sq ft to make up for the heat loss the total fuel saved can be estimated at 24 000 btu/sq ft. Transfer Means The most common method of transferring molten metal from the central melter to other holding furnaces is via a transfer ladle from a furnace tap-out hole or pump.
