Abstract

See full text

Disclosed are a method and apparatus for clean, low loss melting of aluminum using heat transfer by convection and radiation in separate stages. Heat input to a melter stage is provided by silicon carbide tubes into which gas-fueled burners fire so that the tubes radiate heat to a molten aluminum bath. Combustion products exiting the silicon carbide tubes pass through recuperators, preheating burner combustion air. The combustion products then are piped to a preheater stage and formed into jets of hot gases. The jets are directed into convective contact with solid aluminum stock as the stock is transported along a conveyor, preheating the stock to a temperature of about 1,000.degree. F. The solid stock then is fed to the charge zone of the melter stage and melted by contact with the molten bath.
