PROBLEM TO BE SOLVED: To provide a brick-laid structure at a furnace bottom of a converter having a bottom-blowing tuyere which can reduce the wear of bricks laid on the entire furnace bottom than in conventional ones.;SOLUTION: The brick-laid structure at the furnace bottom of the converter comprises the furnace bottom constructed with MgO-C bricks having an elastic modulus of ≥15 GPa at room temperature. A part of the furnace bottom is constructed of MgO-C bricks having an elastic modulus of 15 GPa at a room temperature, and a double-tube tuyere is located in the part. The boundary between the MgO-C bricks having an elastic modulus of 15 GPa and those having an elastic modulus of ≥15 GPa at room temperature is located 500-600 mm away from the circumference of the double-tube tuyere.;COPYRIGHT: (C)2005,JPO&NCIPI
