Refractory Raw Materials
BROWN FUSED MAGNESITE
The Fused Magnesite is produced from Magnesite ore by high temperature melting in an electrical are furnace and the cooling, it is characteristic with well grown crystals, and structure homogeneity, excellent stability, good corrosion resistance to slag and high strength at high temperature. It is main raw material for manufacturing magnesite-carbon refractories.
The manufacturers are mainly used in regenerative chamber in the large scale glass furnace by floating method, electrical are furnace, BoF house hold electrical appliances as electrical insulating materials and so on.
