The Use of Dolomite Bricks and the Effect of Slag Format-ion on Basic Linings in Modern Steelmaking Practice

The demands made upon the properties of steel with regard to higher cleanness and lower contents of sulphur and oxygen increase continuously. This has to be taken into consideration by all metallurgical treatments. The modern technology of "Secondary Steelmaking" transferred metall-urgical processes out of the primary melting facilities into subsequent "secondary" units. Consequently, these units must also be lined with refractories compatible with these metallurgical requirements (1-4).
