Control Oxygen-Converter Process in Closed Loop

The work was done in order to increase the efficiency of BOF smelting by constructing closed-loop control system. The creation of BOF melt models was based on the combined modeling method, which includes deterministic, probabilistic and heuristic approaches, methods of automatic classification and the positive experience of the previous administration. A closed-loop system including a static, dynamic and closed control model BOF steelmaking process was developed.

A dynamic model of temperature control converter baths

In this paper, we analyze the existing methods of temperature control of the oxygen - converter bath. We investigate the balance method of temperature control, kinetics of burning iron impurities, assimilation of bulk materials, heating of the lining and its relation to changes in the bath temperature. Finally, we present the simulation results of converter melting under the temperature conditions.
