The results shown in FIG. 2 ta+ show that the variation in temperature distribution is small and that the blast furnace is in a normal operating state. The observation results in the raceway corresponded to the quality of the hot metal after about 2 hours, especially in the hot metal (Si), and the quality at that time was the value shown in Table fa).

に回復しているが、ばらつきがまだ大きい状態である。Table 1. (Si) in hot metal after about 2 hours Figure 2 (bl) shows a state in which the coke temperature in the raceway has decreased and the dispersion has increased due to fluctuations in blast furnace operation.If this state continues, approximately After 2 hours, as shown in the table (bl), /8 pig iron (Si) decreases and the variation increases.Therefore, based on the observation results in Figure 2 fb), action was taken to increase the coke ratio ■10 kg/l.
