Patent

CA 2138718

A process for producing iron from ferrous raw materials is disclosed. Fuels, oxygenous gases and ferrous raw materials are introduced into a converter containing an initial iron smelt during the production phase. The reaction gases are afterburned with oxidizing gases in the gas space of the converter above the smelt and the resulting heat transferred to the iron bath. A partial amount of iron is tapped after the production phase and a next initial iron smelt is left remaining in the converter for the next production phase, wherein the initial iron smelt comprises between 10% to 60% of the total iron smelt weight in the converter prior to tapping the partial amount of iron.
