摘要： PROBLEM TO BE SOLVED: To develop a technology for performing a stable operation of a blast furnace by correctly grasping gas and liquid permeability in a lower part of a blast furnace under operation.
SOLUTION: An assumed drop of the blowing pressure at a lower part of a blast furnace 1 under operation is obtained, and the grain size of filled stuff in the lower part of the blast furnace is estimated using the assumed drop. The assumed drop of the blowing pressure in the lower part of the blast furnace under stable operation is obtained in advance, and the grain size of filled stuff in the lower part in that condition is estimated by using both assumed drops. The ratio of the grain size of the filled stuff in the blast furnace under operation to the grain size of the filled stuff under stable operation is used as an index of the operational stability of the blast furnace. In a method for obtaining the assumed drop, the assumed blowing pressure P
b ' on the tuyere axis 4 is obtained by using the pressure in the vicinity of the inner wall of the furnace at two or more points belonging to a tapered part 10 above the tuyere, and the differential pressure between P
b ' and the measured pressure P
min at the highest position among the two or more pressures is defined as the assumed drop. The average grain size of the filled stuff in the lower part is obtained from the assumed drop by using the Ergun formula.
