Method for preparing ferrocarbon intermediate product for use in steel manufacture and furnace for realization thereof

Abstract From the Canadian patent

The hereinproposed method and furnace provide for preliminary building up of melt in a melting pot of a rectangular shape in the horizontal section, delivery of an oxygen- -containing gas into the melt below its surface level through tuyeres with nozzles installed in the longer walls of the melting pot, creating two melt zones: an upper zone loaded with solid carbon fuel in an amount sufficient for providing a volumetric concentration of said fuel within 0.5 to 50% of the melt volume in said zone, wherein said concentration is maintained by subsequent concurrent loading of iron-bearing material and solid carbon fuel, and a lower zone consisting of a layer of slag and a layer of ferrocarbon …
