Abstract:
1. A method of regulating the output of CO in steel production, the method comprising the steps of: supplying oxygen to a melt in a steel production process to remove carbon present, determining an actual value of a carbon stream which is released from the melt, determining an amount of oxygen supplied to the melt, determining a carbon content of the melt, calculating an expected value of the carbon stream based at least on the determined amount of oxygen supplied to the melt and the determined carbon content of the melt, comparing the determined actual value of the carbon stream with the expected value of the carbon stream, and based on the results of the comparison of the actual value of the carbon stream with the expected value of the carbon stream, determining whether to take a corrective measure, wherein the corrective measure includes either supplying additional carbon to the melt or adjusting the amount of oxygen supplied to the melt.
