Abstract

Although many efforts have been made to control the burden distribution, there was not yet adequate information to obtain the best control. Therefore, Nippon Kokan K. K. built a full scale 36° segment model equipped with two bells, movable armors, a burden discharge facility and a cold blast supply facility. A number of experiments were made to obtain the burden and gas distribution.
The results of these experiments have been utilized to improve the burden and gas distribution in Fukuyama No. 4 BF; the change from two-batch charging to one-batch charging leading to a more uniform burden distribution resulted in the decrease in fuel rate by 10 kg/THM.
