ALUMINUM MELTING WITH REDUCED DROSS FORMATION |
摘要 |
An aluminum melting method wherein an atmosphere above the aluminum charge is comprised of two strata, a lower strata covering the aluminum charge comprised of a non-oxidizing gas and an upper strata comprised of combustion gases from one or more burners. Heat from the burner or burners radiatively heats and melts the aluminum while the lower strata protects the aluminum from oxidative effects which would result if the aluminum surface were contacted with the combustion gases, thus serving to reduce dross formation.
