Abstract

The converter base includes tuyeres formed by two concentric tubes. Through the central tube, an oxidising gas, such as commercially pure oxygen, is blown. Natural gas is blown in through the peripherical tube. During the refining operation, iron ore is added to the metal bath. Pref. the iron ore is at least partially pelletized.
