<p><P>PROBLEM TO BE SOLVED: To recycle an end-of-life vehicle (ELV) as an iron resource without shredding it, or without producing shredder dust. <P>SOLUTION: When cubic waste car press scraps 15 obtained from the ELV without shredding are melted together with municipal scraps 16 with the use of a melting apparatus having a melting chamber 2 and a preliminary heating chamber 3 connected directly to the melting chamber, the car press scraps with the total length L of three sides of at least 1,300 mm are used. The mixing ratio R of the car scraps in relation to the removal rate X of combustible members from the car meets formula (1) of R≤0.6X+30, and the ratio R in relation to the total length L meets formula (2) of R≤-(1/30)L+120. The car scraps and the municipal scraps are melted while being supplied to the preliminary heating chamber so that the car scraps are kept unmelted in the melting chamber and the preliminary heating chamber and discharged when a prescribed amount of molten metal 17 is produced. <P>COPYRIGHT: (C)2003,JPO</p> |
