3 パラレルバンカー型ベルレス装入装置による細粒原料多量使用時の高炉装入物分布制御 Blast Furnace Burden Distribution Control with 3 Parallel Bunker Bell-less Top Using Large Amount of Small-Sized Sinter

廣瀬 茂行(Shigeyuki Hirose) 菅原 英世(Hideyo Sugawara) 谷吉 修一(Syuichi Taniyoshi) 要旨 : 水島製鉄所第3 高炉は 3 次改修において,高度な装入物分布制御を実現するために 3 パラ レルバンカー型ベルレス装入の導入を行った。本装置により原料装入能力が大幅に向上し、 コークス垂直装入、鉱石粒度別分割装入を含む多バッチ装入が可能となった。また半径方 向の粒度編析を強化するため新型の炉項バンカー形状を採用し、積極的な細粒原料の使用 技術の拡大を図るとともに、リアルタイムの原料装入速度一定制御を開発し、制御性の大 幅な向上を達成した。第 3 高炉ではこれらの装入物分布制御技術により小塊焼結鉱使用比 率17%の安定使用を継続している。 Synopsis :

A three parallel bunker bell-less top was installed at Mizushima Works’ No.3 blast furnace for the third campaign in order to employ highly sophisticated burden distribution control techniques. The burden distribution control techniques make it possible to increase the rate of small-sized sinter with the multi-batch charging as the two-size fraction charging of coarse and fine sinters and the vertical coke charging. The authors have introduced a new type of top bunkers, which has strengthened the radial size distrivution of coke and ore, and the real-time control system, which has enabled the constant flow rate during charging as well as the precise charge and control. Through these burden distribution measures, 18% small sinter has been stably charged at No.3 blast furnace.
