FIELD: wall structures for furnace, in particular for metallurgical furnace such as high-temperature blast furnace. SUBSTANCE: structure has steel outer wall and firebrick lining on its inner side which incorporates one or more layers of material of high thermal conductivity; it also has means for cooling wall structure. In addition wall structure is provided with solid metal filler of high thermal conductivity placed in clearance of fire-brick wall structure; filler is melted inside clearance and upon hardening builds up low thermal resistance within clearance. EFFECT: reduced wear and improved service life of wall structure. 18 cl, 3 dwg, 3 ex
