MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.
