Abstract (en)
[origin: CA2705434A1] The present invention relates to a method and an apparatus for the production and the melting of liquid pig iron or of liquid steel intermediate products in a melt-down gasifier, with the introduction of oxygen-containing gas through oxygen nozzles into the solid bed. According to the invention, in the case of at least one oxygen nozzle, at least two gas streams are introduced. As a result, the risk of the fluidization of the solid bed is reduced, and the number of raceways is increased.
