Abstract (en)
[origin: WO9901583A1] The invention relates to a method for producing liquid metal, in particular liquid pig iron (9) or liquid steel intermediates from metalliferous elements, in particular from partially or totally reduced sponge iron (3) in a melt-down gasifier (1). Carbon-containing material, consisting at least partially of coal fines (16) and coal dust (13), is fed with oxygen or an oxygen-containing gas to a bed (4) formed of said carbon-containing material. The metalliferous elements are melted down, forming a reduction gas, optionally after preliminary final reduction. After drying, the coal fines (16) and coal dust (13) that are to be used are mixed in the warm state with bitumen (20) and then briquetted in the cold state. The briquettes (25) thus produced are introduced to the melt-down gasifier (1) in the cold state and subjected to shock heating (1).
