Consideration on Decarburization Reaction in an Oxygen Converter and Possibility of the Computing Control on its Basis

Abstract

Considerations and analyses were done on the mechanism of decarburization reaction in the oxygen steelmaking process by the data obtained from the laboratory work, the open hearth furnace, and the oxygen converter.
Authors found that the blowing time of an oxygen converter could be specified into the three periods according to the characteristics of decarburization reaction which takes place in the vessel. Authors connected it with a control system for the converter practice, and named it “Decarburization Model System.”
As the result of many trials, authors pointed out a possibility of computing control of bath carbon and temperature in this direction.
