STEEL TEEMING LADLE Russian patent published in 1997 - IPC

Abstract RU 2096129 C1

FIELD: steelmaking. SUBSTANCE: invention relates to steel teeming ladles employed in flow evacuation of steel in continuous casting process. Working layer of lining of ladle bottom consists of a region made of dry-put non-baked pitch-dolomite bricks and a region made of dry-put non-baked periclase-chromite bricks. Area of the latter is 0.2-0.4 that of ladle bottom and comprises nozzle- pocket blocks with gaps constituting 0.2-0.3 greatest size of nozzle- pocket block in plane and filled with high-silica mass on aqueous mortar. EFFECT: improved performance characteristics of ladle. 2 dwg , 1 tbl
