抄録

A rigorous evaluation of the usefulness of some existing models for prediction of sulphide capacity and sulphur distribution for industrial slags at Ovako Steel AB has been carried out. The results show that the best agreement between calculated and analysed sulphur distributions is obtained by calculating the alumina activity in the slag from an expression suggested by Ohta and Suito, ²⁶⁾ then using these data to calculate the oxygen activity in the molten steel, and finally by applying the KTH model^4-6) to calculate the sulphide capacity and sulphur distribution. Therefore, the conclusion is that the KTH model^4-6) is a useful tool for predictions of sulphur distributions for ladle slags.
