MZ was made primarily of pure magnesite of various sizes and burnt under media to high temperature. It has excellent resistance to strong alkaline slag attack, alkaline vapour erosion, oxidation-reduction erosion and good thermal conductivity. However, it is average in thermal fatigue resistance, and wear-resistance erosion. It is poor in thermal shock stability, and bad resistance to acidic slag attack.
It is widely used as the working lining, safety lining and permanent layer of traditional steel and nonferrous metal smelting furnaces, such as OHF Furnaces, EAF Furnaces, Converters, Mixers, Flash Smelting Furnaces, Copper Converters, Reverberatory Furnaces etc.
