A method for producing iron in an elongated reaction vessel provided with underbath nozzles and top blowing means in which carbonaceous fuels, iron ore and/or prereduced ore are fed to the melt and in which the reaction gases escaping from the melt are afterburned with oxygen-containing gases in one or more stages, the waste gas aperture of the reaction vessel being offset from the reaction zone of the cabonaceous fuels and thus disposed outside the eruption and splashing area, and the waste gas temperature in the waste gas conduit connected to the waste gas aperture being held above the soldifying temperature of the droplets carried along in the waste gas stream, and the waste gas then being cooled to less than 1000.degree. C. in an adjoining chamber.

Method for producing iron

A method for two-stage melt reduction of iron ore, in which iron ore is prereduced substantially to wustite and at the same time melted down in a melting cyclone, and then liquid hot metal is produced in an iron bath reactor connected to the outlet of the melting cyclone and receiving the melted wustite by adding carbonaceous fuels and oxidizing gas to the melt. The resulting reaction gas from the melt is afterburned, and the dust-laden, partly burned reaction gases from the iron bath reactor are accelerated and further afterburned by adding a hot blast with a temperature of 800.degree. C. to 1500.degree. C., and at least a portion of such accelerated, after burned reaction gases are introduced into the melting cyclone to reduce and melt fresh iron ore.
