The process analysis of the oxidizing period was carried out by using a 2 ton arc furnace. The changes of and the relationship among C, Si, Mn, Cr, Fe in the melt and the bath-temperature during oxygen blowing were analyzed.
A method of controling the carbon content after oxygen blowing was established by using a mathematical model obtained according to that analysis.
The controling accuracy of carbon content obtained by that mathematical model was twofold better than that of conventional method.
The greatest merit of the controling method by means of the mathematical model lies on the fact that even an unexperienced operator can control the carbon content after oxygen blowing easily and accurately. Furthermore, an operator-guide-control-system by a computer can be introduced into stainless-steel-melting.
