    The paper describes an investigation of the influence of increasing carbon content on the corrosion of MgO-C refractory material by molten slag. The refractory material contained mass fraction of 98 ... % MgO, approximately 2 % Fe[sub]{2}O[sub]{3}, and graded quantities from 3 % to 18 % C. The corrosion was investigated in melts of reduction ladle slags at a temperature of 1600 [compositum]C in laboratory conditions. A sample of refractory material with dimensions of 10 x 10 x 100 mm was submerged into the molten slag and exposed to the corrosive effect of the slag for 60 min. After the expose of the refractory material the slag was cooled down and submitted to a chemical analysis. After a comparison of the MgO content in the melt was determined andthe degree of corrosion of the refractory material was quantified. The experiments were realised using final slags from the ladle furnace (LF), strongly alkaline slag w(CaO)/w(SiO[sub]2)=0.94 with different contents of CaF[sub]2. The work was carried out within the frame of the projects EUREKA E!3580 and IMPULS FI-IM4/110.
