摘要： 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).

摘要： A method for producing liquid pig iron or steel intermediate products made from lumpy ferriferous material in a melt-down gasifier, whereby coal and gas containing oxygen are added, a reduction gas is formed simultaneously and the ferriferous material is melted. Pieces of coal are introduced into the melt-down gasifier from above, forming a static bed in the melt-down gasifier in conjunction with the ferriferous material, whereby said coal discharges its proportion of volatile hydrocarbons into the domed area above the static bed and the dust burner is inclined from above at an angle to the surface of the static bed. The dust burner is operated and controlled in such a way that combustion of at least 40 % of the proportion of carbon in the fine-particled carbon carriers results in the production of CO2. The invention also relates to a device for carrying out said method. The invention makes it possible to reduce the amount of dust discharged from the melt-down gasifier with the reduction gas and to reduce the tendency of any further discharged dust to agglomerate.
