| Zusammenfassung: | To control ore terrace length in a proper range, achieving the stable operation of a blast furnace.SOLUTION: In a blast furnace operation method, an ore layer and a coke layer are alternately and laminarly formed in a furnace, and the deposition shape at the furnace top is inclined downward to the furnace center. A length evaluation value for evaluating the ore terrace length of the ore layer formed in the furnace is acquired for each of a plurality of furnace radial directions. A representative value determined on the basis of the acquired length evaluation values is used as an operation management index to conduct operation.SELECTED DRAWING: Figure 2
【課題】鉱石テラス長さを適切な範囲に管理することにより、高炉の安定操業を実現する。【解決手段】 鉱石層とコークス層とを炉内に交互に層状に形成し、炉頂での堆積形状を炉中心側に向かって下向きに傾斜させる高炉の操業方法において、炉内に形成される鉱石層の鉱石テラス長さを評価するための長さ評価値を複数の炉径方向のそれぞれについて取得し、前記取得された複数の長さ評価値に基づき決定した代表値を操業管理指標として操業する高炉の操業方法。【選択図】図２ |
