A new bell-less top was installed at Chiba No.6 blast furnace in 1998 for advanced burden distribution control. Reduced scale model experiments were used to develop the rotating chute with stabilizer and the reverse-forward tilting function. Furthermore, an accurate simulator for burden distribution was developed. The results obtained allowed to implement an operational trial of reverse tilting charging. Burden profile and gas distribution could be controlled satisfactorily with this method.
1998 年,千叶六号高炉安装了新的无料钟炉顶,以实现先进的炉料分配控制。采用缩小比例模型实验开发了带有稳定器和反向前倾功能的旋转溜槽。此外,还开发了一种精确的负荷分配模拟器。所获得的结果允许实施反向倾斜充电的操作试验。用这种方法可以令人满意地控制炉料分布和气体分布。
