Abstract: To provide a method for protecting furnace bottom bricks in a blast furnace capable of continuing operation of the blast furnace without wear of the furnace bottom bricks and achieving the stable operation and the long service life of the blast furnace.SOLUTION: In the method for protecting furnace bottom bricks 5 of a blast furnace 1 according to the present invention, the temperature of the furnace bottom bricks of the blast furnace 1 is measured as a preliminary preparation step to obtain the highest temperature of the furnace bottom bricks 5. The relationship (a) between the highest temperature and the CR indicator value which is the "coke ratio-solution loss carbon quantity" is determined, and the threshold value of the CR indicator value is determined from the relationship (a). In the actual operation of the blast furnace 1, the CR indicator value in the actual operation is obtained and compared with the threshold value of the CR indicator value. When the CR indicator value in the actual operation of the blast furnace 1 is equal to or lower than the threshold value of the CR indicator value, the operating condition of the blast furnace 1 is adjusted so that the CR indicator value in the actual operation of the blast furnace 1 exceeds the threshold value of the CR indicator value in order to protect the furnace bottom bricks 5 of the blast furnace 1 while continuing the operation of the blast furnace 1.SELECTED DRAWING: Figure 1
