  • Packaging for reclaiming scrap metal
    Patent number: 4244492
    Abstract: Metallic scrap such as is recovered from metal turnings, borings and punchings is packed into a laminated fiber board container which is sealed and then introduced into an operating metal-melting furnace. The fiber board container resists combustion long enough to permit the scrap particles to reach the melt zone preventing entrainment of the scrap in the hot gas blast. This greatly reduces the loss of scrap particles from the furnace and aids in atmospheric pollution control.
