and Automation in Blast Furnace Yunosuke Maki, Akihiro Inayama, Katsumi Ino |
| Synopsis: Kawasaki Steel has modernized blast furnace control systems featuring an integrated instrumentation and electrical system for each sub-process, a human-machine interface through a single window, and a distributed process computer system. A furnace diagnostic system, the "GO-STOP system", has been developed into a knowledge-based system that provides appropriate action guidance. For burden distribution control, controllability and flexibility have been improved by the use of a bell-less-top charging device. For hot stove control, the automatic setting of combustion gas flow rate and improved efficiency have been achieved by a fuzzy control system. Furthermore, the recent remote operation of cast house equipment has helped to improve the working environment and efficiency at Chiba Works No. 6 blast furnace. |
