Dolomite as a Refractory Raw material for Lining L.D Converters

Abstract

The service conditions in L.D converters are dealt with and the existing refractory practice of lining these vessels is reviewed. Factors affecting, the lining wear and the role of carbon in tar bonded refractories have been discussed. The choice of refractory and the advantage of dolomite over other types of materials have also been dealt with. The suitability of Indian raw materials namely—dolomite, dolomitic magnesite and magnesite as well as suitable methods of their calcination for use as lining material for L.D vessels are described.
