Abstract

A converter process according to the present invention comprises application of an electromagnetic travelling field through the converter walls (10, 12, 14) during different stages of the conversion process. The electromagnetic travelling field induces an additional stirring flow. The converter process according to the present invention may also comprise slag splashing. A converter device according to the present invention similarly comprises, beside a converter enclosure (1) and a gas injection lance (2), an electromagnetic stirrer (3) acting through the enclosure walls (10, 12, 14).
