What are the characteristics of large crystalline fused magnesia products

The main content of large-crystal fused magnesia is 97%, 97.5%, 97.8%, 98%, 98.5% and 99%. The large-crystal fused magnesia has high purity, large melting of crystal particles, high melting point and dense texture; Good thermal shock stability, electrical grade magnesia powder, 97 fused magnesia, 98 fused magnesia, and large crystalline fused magnesia have good high temperature bending strength, slag resistance and corrosion resistance; Strong thermal conductivity and high insulation. Large-crystal fused magnesia is mainly made of 98% magnesium oxide, which is sintered by 3000KVA electric melting. It is electric grade magnesia powder, 97 fused magnesia, 98 fused magnesia

This paper introduces the raw materials used for processing large crystalline fused magnesia. Large-crystal fused magnesia is an alkaline refractory. Large-crystal fused magnesia products are characterized by high purity, good calcium-silicon ratio, large crystal particle size, and stable physical and chemical properties. Large-crystal fused magnesia is mainly used in the industrial fields of metallurgy, chemical industry, electrical appliances, aerospace, and national defense. Magnesite ore with a content of more than 46% is mainly selected. When the magnesite ore is calcined and heated to 1400-1800 ℃ in a high-temperature shaft kiln, Mg (CO3) is completely decomposed to form periclase, which becomes a hard reddish-brown calcined magnesium, It has high fire resistance. It is an ideal raw material for the production of unshaped refractory materials. The products are used for the steel making open hearth, electric furnace bottom and ramming furnace lining.
