抄録

The corrosion of fused silica refractories in molten CaO-Al₂O₃-SiO₂ slag was studied. The experiment was carried out with a rotating cylindrical specimen. The retults are as follows:<br>(1) The diameter of specimens decreased linearly with time. The increase both in temperature and rotating speed promoted the corrosion.<br>(2) A thin reaction layer was observed on the surface of the specimen. The change in SiO₂ concentration in the slag was best described by a rate equation (which was derived) for the mass transport controlled mechanism. The apparent activation energy of corrosion was 64kcal/mol, implying that the corrosion is controlled by diffusion of ion in the slag.<br>(3) A non-dimensional equation κ=αU^0.67 was obtained, the exponent of which agreed with the literature values.
