Popis: Zirconia graphite refractory is used in continuous casting of steel. Slag corrosion resistance influence on time of casting. With factorial experiment 25-1 influence mixture of refractory (content of graphite, silicon carbide, boron carbide) on oxidation resistance and interaction with mould powder (C/S = 1, F = 8 %) at 1400 °C. Boron carbide is better antioxidant than silicon carbide. Boron carbide 3 % mass decrease slag corrosion resistance of ZG-refractory. The thicknesses de-carbonized layer are within 1–7 mm Additives of boron carbide and silicon carbide reduce the thickness of the oxidized layer. It was established experimentally that the boron carbide has the best antioxidant properties than silicon carbide therefore, in the study circolatorio materials action SiC less effective than B4C.
