direct reduction vessel, copper or copper alloy cooler for refractory material cooling and cooling elements for location on a refractory lined threshold of a direct reduction vessel

摘要

UM DIRECT REDUCTION VASE, COPPER COOLING OR COPPER ALLOY FOR COOLING REFRACTORY MATERIAL AND COOLING ELEMENTS FOR LOCATION IN A COATED REFRACTORY SIDE OF A DIRECT REDUCING VASE MV expands a direct vessel. and a threshold cooling element. The vessel includes a refractory-lined threshold. An internal surface of an upper part of the sill extends upwards and out of the side walls of the vessel. The upper part of the sill incorporates a sill cooler disposed externally behind the refractory lining of that part of the sill and below the cooling panels on the side walls of the vessel. The sill cooler comprises a plurality of cooling elements. Each cooling element is provided with a hollow body structure open at the rear, with base, top and side walls formed integrally in a molten structure and incorporating refrigerant flow passages.
