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.
Claims9
In a method of operating a steel converter which has a basic wear-lining formed of refractory material at least partly composed of burnt magnesite, including the step of performing maintenance on the said lining by intermittently spraying refractory material onto the wear-lining and/or slagging-in while the wear-lining is hot, the improvement that the particles of the magnesite component of the wear-lining contain on average more than 6% monticellite.
Method of providing and maintaining a wear-lining of a steel converter, comprising the steps of (a) initially providing a basic wear-lining of refractory material which is at least partly composed of burnt magnesite which consists of particles containing on average more than 6% monticellite and (b), during the operation of the steel converter, intermittently spraying refractory material onto the hot wear-lining and/or slagging-in.
A steel converter having a basic wear-lining formed of refractory material at least partly composed of burnt magnesite, wherein, in order to improve the wear-resistance of the lining when maintained during operation of the converter by spraying refractory material onto the hot wear-lining and/or by slagging-in, the particles of the magnesite component of the wear-lining contain on average more than 6% monticellite.
