Abstract

The basic wear-lining of a steel converter is made of refractory material at least partly composed of burnt magnesite. Maintenance is performed by spraying refractory material onto this lining or by "slagging-in". The effect of this maintenance procedure, in terms of the duration of the lining, are improved if the particles of the magnesite component of the wear-lining contain on average more than 61/4 percent monticellite. Material of this kind has not in the past been found suitable for a wear-lining.
