<p>PROBLEM TO BE SOLVED: To apply recycle treatment to spent cars and spent electric home appliances generated in large quantities as an iron source without treating them with a shredder. SOLUTION: When a waste car scrap or a waste car pressed scrap or a waste electric home appliance scraps obtained from the spent car or the spent electric home appliances without treating them with the shredder, is melted as a melting raw material 16 in a melting chamber 2 having a heating source 19, gasifiable component in the melting raw material is gasified by preheating the melting raw material and thereafter, the melting raw material is charged into the melting chamber and melted. In this time, it is desirable to gasify in a preheating chamber 3 directly connected with the melting chamber and to use by mixing the produced molten metal 17 with molten iron in a blast furnace.</p> |
