    In this paper the influence of the CaF2 amount in steelmaking slags on the CaO and Al2O3 activities is presented. The new analytical model (RMJ) for determining the sulphide capacity was derived. The ... aim of this model is to adjust and correct some models, according to Tsao, Daffy and Young, that had limitations regarding the presence of CaF2 in the slag. Using the RMJ model, the effect of CaF2 on the sulphide capacity and desulphurisation degree is more precisely defined. Calcium fluoride decreases the negative effect of Al2O3 on the sulphide capacity. For an investigation under production conditions, several types of carbon and low-alloy steels were chosen. The steels used for the analysis of specified process parameters were produced using a mixture of CaF2-CaO and CaO-CaF2-white bauxite (WB) as the flux. For specified cases, the results obtained with the RMJ model as well as with the Young model, were presented. The RMJ model defines correction factors k1(CaF2) and k2(CaF2). It can be seen that the certainty factor of linear dependence is a bit larger in the case of the RMJ model than the one obtained with the Young model.
