An analysis of metal and slag composition data gathered during the operation of a 6-1/2-ton basic electric-arc furnace is made for the purpose of quantitatively describing the refining processes of dephosphorization and desulfurization. A kinetic model is proposed, and the data is examined in light of the model; agreement with theory is shown. Relations are obtained correlating metal and slag composition with the rate the refining processes. The results and their ramifications are discussed with reference to the proposed model actual operating procedure, extrapolation, and optimum processing time.
