Fused Spinel powder

After the spinel is a high-purity alumina and calcined magnesite as the main raw material in electric arc furnace above 2000 ℃ high-temperature fused it cooled synthesis of a new type of high-purity refractory raw materials. It has the volume density, good thermal shock resistance, anti-erosion ability. Laboratory studies and proved spinel refractory products added to the preform, unshaped refractory material can effectively improve slag resistance and thermal shock resistance. Spinel is mainly used for the production of high-grade aluminum-magnesium brick, high performance aluminum-magnesium castable, slide gate, ladle lining brick, casting skateboards, nozzle brick hearth furnace roof tiles, etc., can improve the thermal shock resistance of the material It is the ideal raw material used to replace arc furnace cooling molten magnesium chrome refractories made after a high-purity refractory materials.
