BOF

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.

Investigation of the Economic Efficiency of Automation Bof Production

The influence of technological and human factors on the cost of steel, the improvement of the process and the organization of production were investigated. Technological factors include the basicity of slag, lining life, rate of oxygen input, changes in nitrogen content in the metal, clean of blowing, conditions of slag formation. Statistical relationship between the lining life and the basicity of slag was obtained.
