In the practice of deoxidation with synthetic slag, we usually use the slag from the binary systems: CaO-AI;Oj, C'aO-TiO; and CaO-CaF; or from the ternary systems: Ca0-Si0;-AI20j and CaO-CaF;- AI^Oj. According to the literature, the best results were obtained with synthetic slag from the binary system CaO-Al:Oj (50-52% CaO and 38-42% Al;03 ). The paper presents the results of laboratory experiments on steel desulphurisation with slag from the system CaO-SiOj- TiO:. To determine the influence, on the desulphurisation process, of the titanium oxide added in calcium aluminates slag, we experimented, in the laboratory phase, the steel treatment with a mechanical mixture consisting of lime, aluminous slag and slag obtained from the titanium making process through the aluminothermy technology. The steel melting was carried out in an induction furnace of 10 kg capacity, existent in the "Metallic Melts" laboratory of the Engineering Faculty of Hunedoara. During the research, we aimed to establish correlation equations between the sulphur distribution coefficient and the slag components (CaO, AI2O3. TiO:. FeO. MgO and MnO). The data obtained in the experiments were processed in Excel and MATLAB programs, resulting simple or multiple correlation equations, which allow ed the elucidation of some physical-chemical phenomena specific to the desulphurisation processes.
