| Blast Furnace Burden Distribution Control with 3-Parallel Bunker Bell-less Top Using Large Amount of Small Sinter Shigeyuki Hirose, Hideyo Sugawara, Syuichi Taniyoshi |
|
Synopsis : A three-parallel bunker bell-less top was installed at Mizushima Works No.3 blast furnace for the third campaign in order to realize highly sophisticated burden distribution control techniques. These control techniques make it possible to increase the ratio of small sinter in multibatch charging using two-size fractional charging of coarse and fine sinters and vertical coke changing. The authors also introduced a new type of top bunker which has strengthened the radial size distribution of coke and ore, and a real-time control system which ensures a uniform flow of materials. These burden distribution measures have greatly improved the charging function and enhanced controllability, making it possible to stably charge small sinter at a high rate of 17%. |
