Abstract

A refractory composition for use, preferably as a lining of a metallurgical vessel is disclosed. The refractory composition includes sintered oxide granulations, based on magnesium oxide, dolomite, calcium oxide or a combination thereof, an organic binder having a mixture containing carbomethoxy-substituted oligophenyls, carbomethoxy-substituted benzyl esters or a combination thereof, and 0 to 20 parts by weight of a fine particulate carbon carrier per 100 parts by weight sintered oxide. A process for the production of a pressed body employing the refractory composition of the invention is also disclosed.
