FIELD: methods of production of molten pig iron or semi-finished steel products from ironcontaining material, from reduced sponge iron in particular. SUBSTANCE: proposed method is performed in melting gasifying apparatus where iron-containing material is molted in layer formed by solid carbon carriers at delivery of carbon-containing material and oxygen at simultaneous formation of reducing gas. Fine-grained reduced material and oxygen are introduced in this layer from the side. Fluidized layer of fine-grained solid carbon carriers and fine-grained ironcontaining reduced material is maintained above stationary layer formed from solid carbon carriers. Fine-grained reduced material is placed in fluidized layer at direct contact with oxygen, preferably in form of flow having circular cross section and surrounded by oxygen jet over periphery with oxygen enclosed inside it, thus ensuring loading of material without briquetting and without entrapping it from apparatus by reducing gas generated in it. EFFECT: enhanced efficiency. 13 cl, 2 dwg
