Abstract

A known type of tuyere comprising two coaxial tubes blowing O2 surrounded by a pref. endothermic dissociation, protective gas into a melt is situated in the lower part of the lateral wall of the converter. Esp. the converter has a solid bottom. The situation of the tuyere improves the life of refractory linings esp. the bottom lining.
