The present invention relates to a method for producing a refractory brick containing magnesia, which uses a magnesium mixture produced in the production of a magnesium plate to improve abrasion resistance, to have sufficient mechanical strength for high temperature heat action, Also stable. Further, it is possible to produce refractory bricks of homogeneous quality by using only magnesia, no carbon oxidation problem, excellent oxidation resistance, and coating the surface of the particles of magnesia to produce a refractory brick composition. |
