Abstract

A process for the production of iron from ferrous raw materials, the process comprising conducting a production phase and a tapping phase, the production phase including feeding fuel to an iron bath contained in a converter, continuously feeding ferrous raw materials to the iron bath through a gas space above the iron bath, continuously blowing oxygenous gases onto the surface of the iron bath, reducing the ferrous raw materials with the fuel to produce reduced iron, afterburning reaction gases comprising CO and H.sub.2 emerging from the iron bath with oxidizing gases in the gas space to produce heat, and transferring the heat to the iron bath; and the tapping phase including removing 40% to 90% of the iron bath to produce a final bath which can then be used as an initial bath in a subsequent production phase.
