| Synopsis: In Kawasaki Steel Corp., the computer control system for sinter plants was revamped, using the latest distributed control system (DCS), centralized process computer system (P/C) and central computer systems (C/C) of the respective Works. DCS performs functions such as measuring wind velocity distribution and gas temperature distribution along the sinter strand, and also Direct Digital Control (DDC). P/C performs functions such as process control to optimize sinter plant operation, and information services to operators. C/C performs functions such as planning, managing, and data analysis of production and operation based on the general-purpose data base. This 3-layer hierarchical system was completed in 1982 at Mizushima Works and was later completed at Chiba Works. It has brought about saving of operational cost and enhancement of operational management level, and been constructed as a step to the reconstruction of the total ironmaking information system of the entire company. |
