METHOD OF OPERATING A STEEL CONVERTER, METHOD OF PROVIDING AND MAINTAINING A WEAR-LINING OF A STEEL CONVERTER AND A STEEL CONVERTER HAVING SUCH A LINING

摘要

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 a refractory material onto this lining and/or coating the lining with slag. The effect of this maintenance procedure, in terms of the duration of the useful life of the lining, is improved if the particles of the magnesite component of the wear-lining contain on average more than 6-1/4 per cent monticellite. In the past, material of this kind used on its own has not been found suitable for a wear-lining.
