BEJANA METALURGI YANG DITINGKATKAN DAN METODE PENGGUNAAN BEJANA TERSEBUT

摘要

A metallurgical vessel having a sloping bottom surface (112) which includes a tapered upper surface (112a) terminating at a vertical surface (126b), wherein the vertical surface (126b) terminates at a lower tapered surface for forming a pocket block reservoir (120) such that the pocket block reservoir (120) has a volume of less than or equal to about five percent of the total volume of the metallurgical vessel is disclosed. This pocket block reservoir (120) provides an area for the accumulation of residue metal and slag when the metallurgical vessel is discharged, therefore resulting in a significant increase in the quantity of usable pure metal discharged from the metallurgical vessel and thus contributing to improved volumetric efficiency of the vessel. A method for improving the yield efficiency in the production of metal employing this vessel is also provided.
