Corrosion of magnesia carbon brick by ladle slag

In the ladle due to the complex physical and chemical environment at the slag line the furnace lining is the most vulnerable to damage The chemical attack of steel slag on the magnesia carbon brick is mainly through the dissolution of magnesia and the oxidation of the graphite in the brick body Under the coined action of the two factors the magnesia carbon brick is damaged

Paper

201752 Carbon bonded magnesia and magnesiaalumina bricks are used in the side walls and bottom of steel ladles for more than 30 years They have to withstand aggressive steel/slag systems in the range of 1600–1750 °C and also provide an excellent thermal shock performance During service or presintering alumina is able to react with magnesia to
