AbstractAccording to the experimental results of hot metal dephosphorization by CaO-based slags at a commercial-scale hot metal pretreatment station, activity of P2O5 in the CaO-based slags has been determined using the calculated comprehensive mass action concentration of iron oxides by the ion and molecule coexistence theory (IMCT) for representing the reaction ability of Fe (t) O, i.e., activity of . The collected ten models from the literature for predicting activity coefficient of P2O5 in CaO-based slags have been evaluated based on the determined activity of P2O5 by the IMCT as the criterion. The collected ten models of activity coefficient of P2O5 in CaO-based slags can be described in the form of a linear function as , in which independent variable represents the chemical composition of slags, intercept including the constant term depicts temperature effect and other unmentioned or acquiescent thermodynamic factors, and slope is regressed by the experimental results. Thus, a general approach for obtaining good prediction results of activity of P2O5 in CaO-based slags is proposed by revising the constant term in intercept for the collected ten models. The better models with an ideal revising possibility or flexibility in the collected ten models have been selected and recommended.
