Abstract

The state of production of magnesia refractories is considered. Ukraine does not produce promising advanced magnesia refractories (periclase-carbon, dolomite-periclase-carbon, and periclase-spinel). Periclase-chromite and chromite-periclase refractories are produced on the basis of imported raw materials of various grades. The technical level of the used equipment does not meet current requirements. The raw-materials base is underdeveloped. In order to bring the production of Ukrainian magnesia refractories to a competitive level have to attain the quality of the world counterparts at a cost 20–30% lower than the world level.
