  • Method and apparatus for preheating scrap
    Patent number: 4135702
    Abstract: A metal batch preheating method comprises positioning an elongate mass of metal scrap on a conveyor in a tunnel furnace for heating such furnace having longitudinally spaced transversely extending zones of greater and lesser heat, the conveyor being loaded with metal for the length of the tunnel furnace except for the last heat zones therein. The metal is thereafter moved through a plurality of "advance and heat" movements in the furnace during the batch heating cycle so that the metal is exposed to both greater intensity and lesser intensity heat zones as it is preheated after which the metal is discharged for use or further processing.
