  • Apparatus and method for manufacturing compressed lump of metal scrap
    Patent number: 9321232
    Abstract: An apparatus and method for manufacturing a compressed lump of metal scrap that is capable of compressing various kinds of collected metal scrap into a standardized form so that the metal scrap can be directly introduced into a blast furnace. A through hole is formed in a compressed lump of metal scrap during manufacture of the compressed lump of metal scrap so that the compressed lump of metal scrap can be efficiently melted and the interior of the compressed lump of metal scrap can be observed.

  • Method of manufacturing compressed lump of metal scrap
    Patent number: 8661971
    Abstract: A method of manufacturing a compressed lump of metal scrap involves forming a through hole in the metal scrap instead of drilling a finished compressed lump of metal scrap to form the through hole in the compressed lump of metal scrap. Friction and stress applied to the core are minimized while the through hole is formed in the compressed lump of metal scrap, which is compressed with high density, thereby minimizing damage to the core and thus minimizing a trouble occurrence rate.

  • METHOD OF MANUFACTURING COMPRESSED LUMP OF METAL SCRAP
    Publication number: 20130112093
    Abstract: Disclosed herein is a method of manufacturing a compressed lump of metal scrap. A through hole is formed in the metal scrap during a process of manufacturing the compressed lump of metal scrap instead of drilling a finished compressed lump of metal scrap to form the through hole in the compressed lump of metal scrap. Friction and stress applied to the core are minimized while the through hole is formed in the compressed lump of metal scrap, which is compressed with high density, thereby minimizing damage to the core and thus minimizing a trouble occurrence rate.
