DEVELOPMENT OF ANALYTICAL AUTOMATION SYSTEM FOR PROCESS-CONTROL IN STEEL MAKING WORKS

An automatic and integrated analysis system for iron and steel making process was developed in Oita Works of Nippon Steel Corporation. This automatic analysis system, in principle, needs no human labor except for instrument calibration and treatment in trouble and performed a large quantity of labor-saving. Analytical precision after automation showed no difference compared with the former system and has given satisfactory results. And also in analysis time improvement can be seen. Thus this automatic system has contributed greatly to the steel production.
