PROCESSING PROCESS FOR IMPROVING THE PERMEABILITY OF METALLURGIC CONTAINER FILLS HAVING PERMEABLE REFRACTORY ELEMENTS, AND MATERIALS FOR ITS IMPLEMENTATION

摘要

TREATMENT PROCESS FOR IMPROVING THE PERMEABILITY OF METALLURGIC CONTAINER BOTTLES PROVIDED WITH PERMEABLE REFRACTORY ELEMENTS FOR THE CONTROLLED INJECTION OF A BREWING FLUID INTO THE MOLTEN METAL BATH. /P P ACCORDING TO THE INVENTION IS CHARACTERIZED IN THAT, A WELL-CASTABLE REFRACTORY CONCRETE IS PREPARED, THAT IS CAPABLE OF REACHING THE BOTTOM OF THE CONTAINER FROM THE SPOUT BY SINKING ALONG THE SIDE WALL, IN THAT, AFTER EMPTYING THE CONTAINER OF ITS CONTENT, IT IS POURED IN THE GROUT, THE CONTAINER IS IN A TIPPED POSITION, THEN IT IS RECTIFIED VERTICALLY TO ENSURE THE DISTRIBUTION OF THE GROUT ON THE BOTTOM, AND IT IS ALLOWED TO DRY AND ENSURE IT IS TAKEN ON THE BOTTOM WHILE NOW IN THE PERMEABLE REFRACTORY ELEMENTS A PRESSURE SUFFICIENT TO PROVIDE A PERMANENT FLOW OF BREWING FLUID. /P P THE INVENTION IMPROVES THE PERMEABILITY OF NEW OR USED PERMEABLE ELEMENTS AND APPLIES IN PARTICULAR TO CONVERTERS. SUFFERING STEEL LAGE OF TOP REFINING OXYGEN.
