FIELD: ferrous metallurgy. SUBSTANCE: invention can be used in design of stack of blast furnace. Proposed blast furnace has metal segments filled with refractory lining in furnace top part and in upper part of its stack at height of one-three layers of burden loaded into blast furnace. Inclination angle of working surface of segments towards furnace axis is equal to 63-85 deg. Blast furnace also includes T-shaped supports mounted to prevent movement of metal segments in horizontal plane and to provide for their vertical movement. EFFECT: prolonged service life of brickwork of stack of blast furnace owing to its improved design. 2 cl, 2 dwg, 4 tbl |
