Abstract
Disclosed herein are 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.
