Method and apparatus for recovering refractory debris and ladle slag as process slag in ferrous metallurgy production at EAF and for performing related metering on a furnace for forming process slag

摘要

A method for the recovery of refractory debris materials and ladle slags as process slags in the iron metallurgy production in EAFs and the related metering to the furnace for the formation of the process slag comprises the following steps: grinding and screening of the refractory debris materials until powders of controlled granulometry are obtained, storage of the powders in storage sites, injection of the powders into an EAF furnace by means of automatic metering of the various components.
