PCT No. PCT/AT93/00158 Sec. 371 Date Oct. 31, 1994 Sec. 102(e) Date Oct. 31, 1994 PCT Filed Oct. 19, 1993 PCT Pub. No. WO94/09163 PCT Pub. Date Apr. 28, 1994.In a process for the continuous melting down of scrap metal, in particular of bales of scrap metal, which contain residual plastic materials, the scrap metal being fed to a melt-down reactor (1) and the heat required to melt this down being obtained by direct heating from below, using burners that are arranged close to the tapping point, the process is managed in the melt-down reactor (1) as a reducing process; part of the process gases is returned to the melt-down reactor (1) as combustion gas after utilization of the sensible heat and purification; the remaining portion is passed out as output gas. This makes it possible to operate without oversize gas purification systems when melting down scrap metal that contains plastic, and to utilize the pyrolysed substances that are contained in the working material to good effect.
