METHOD OF REWORKING SCRAP METAL Russian patent published in 2000 - IPC

FIELD: reworking scrap metal; large steel scrap of extensive length. SUBSTANCE: flow formed in melting unit is circulating melting zone and melt heating zone; scrap metal is delivered at linear velocity ensuring maintenance of mass ratio of scrap metal and melt delivered to melting zone within 0.003-0.30. Scrap metal is delivered continuously. Melt is heated to temperature exceeding melting point by at least 0.4%. Mass ratio of melt running through melting zone per hour to amount of melt in pool is maintained within 2 to 200. EFFECT: increased specific productivity of process; avoidance of preparation of scrap metal for reworking. 3 cl, 1 tbl
