Process analysis of the oxidizing period in stainless steel melting was made by using a 2 ton arc furnace in our Central Reseach Laboratory. Then, carbon control of after O2 blowing was established according to that analysis.Accuracy of carbon control obtained by this mathematical model was so favorable that it was better than two times compared with that of conventional method. It is the most important merit of the control by the mathematical model that even these melters with less experience can control the carbon easily and accurately after O2 blowing, and beside this merit, there are incidental merits as follows:(1) Improvement of yield(2) Decrease of oxygen consumption for blowing(3) Shortening of operating time(4) Elongation of refractory life
