The New Instrumentation System of Chiba Sinterplant and Its Effect in Kawasaki Steel Corporation

Abstract

An integrated systematization has been advanced as one of the means to cope with the recent development in ironmaking technology and energy demend/supply situations. This has been made possible because the processing capacity and safety in operation have been improved due to the advancement of the computer technology; the conventional analog control has been replaced by the overall digital control and just a single large-sized computer now allows the control of process computers which used to be installed independently in each factory.
In the systematization, the construction work is proceeding with a view to reaching such a final goal as the realization of the unified control of the whole process in ironmaking works by means of a large-sized computer. As the first step, the construction of a new instrumentation system for a sintering factory has been made. This paper describes its function and effect.
