Fused cast blocks based on refractory oxides and having a steel member embedded therein

摘要

The invention relates to a fused cast block useful in the construction of steel making furnaces, the block comprising a refractory oxide-based material having embedded therein a steel member which extends over the greater part of the length of the block and emerges from the block on the outer face of the latter, the steel member being embedded in the block in the course of molding the latter and having a cross-section of suitable shape and surface area to impart to the composite block an apparent thermal conductivity at between 500 DEG and 1000 DEG C. of at least 8 Kcal. m./m2. DEG C. hr.
