PURPOSE:To stabilize conditions in a blast furnace by calculating the ratio of the thickness of an ore layer to the thickness of a coke layer from the difference in pressure between plural pressure measuring holes arranged in the furnace in the falling direction of starting materials and by controlling a movable armor on the basis of the calculated value. CONSTITUTION:Plural pressure measuring holes 1a, 2a are arranged in a blast furnace in the falling direction of starting materials at a prescribed distance (DELTAl) from each other. The ratio of the thickness L0 of an ore layer to the thickness LC of a coke layer is calculated from the difference in pressure between the holes 1a, 2a with a data processor 4. On the basis of the output of the processor 4, a movable armor is automatically controlled with a movable armor controller 6. |
