Abstract

A new bell-less top was installed at Chiba No. 6 blast furnace in 1998 for the advanced burden distribution control. Main features of this bell-less top are a rotating chute with stabilizer and reverse/conventional tilting function. These were developed by series investigations by use of reduced scale model experiments. Furthermore, an accurate simulator for burden distribution control was developed. An Operational trial of reverse tilting charging was implemented based on simulation by using the simulator. The controllability of burden profile and gas distribution has been confirmed during the test operation.
