Over the past decade, Magnesia Carbon Brick’s technology has evolved from comparatively modest beginnings into a series of highly sophisticated products tailored to the needs of various steelmaking applications. This evolution to sophisticated products has resulted from a commitment to both compositional development and the development of novel manufacturing techniques. A commitment by steelmakers to a continuing program of service trials has also been a crucial factor in the progress of this field. These efforts have resulted in an understanding of which refractory compositions are best able to give a cost-effective performance under diverse operating conditions. It is anticipated that additional progress will result from continuing work by both steelmakers and refractory suppliers.
