ABSTRACT OF THE DISCLOSURE An internal partitioning wall for a blast furnace stove in which a layer of insulating material is interposed between two layers of refractory material. Buttressing means such as integral, refractory ledges are provided at periodic vertical intervals from one layer of refractory material to the other. These refractory ledges protect the insulating layer from damage due to radially directed compressive forces found to exist in this wall and also reduce deterioration of this insulation due to sagging and vertical compression.
