Aplikace keramických materiálů v ocelářských pánvích

Abstract

The work deals with the problem of refractory materials applied in ladles for current modern methods of steel production. In the introductory section it describes the basic processes of steel production (BOF, electric arc furnace) and basic out-of-furnace steel processes (secondary metallurgy) realized in ladles. The work also deals with the refractory materials (basic, aluminosilicate) used for ladles’ lining with a basic specification of their properties, chemical structure and manufacturing methods. Finally, the work describes construction of ladles‘ lining being used in the out-of-furnace steel processes and the means to increase utilization of the ladles’ lining.
