Abstract

A Basic Oxygen Furnace (BOF), which refines steel, is a typical batch type process, and it has been computer-cotrolled with mathematical models. Since the conditions of materials for the process often vary from time to time, it is important to periodically update the models to keep up with the change of the process. In the Mizushima works, a model analysis system for BOF refining cotrol has been developed in order to easily maintain the accuracy of the models. The system consists of four parts; data extraction, simulation, accuracy evaluation and statistical analysis, thereby statistical models such as multi-regression equations can be automatically analyzed, using accumulated actual data. The system has contributed to the improvement of the model accuracy and consequently to the saving of sub-materials and better hit rate of refining.
