Properties of fused magnesia

Posted time:2021-07-01 Page View:1039

1, ordinary fused magnesia products are mainly made of more than 47% content of magnesite or light burned magnesia as the main raw material in the arc of high temperature melting. It has large grain size, compact structure, strong slag resistance and superior volume stability at high temperature. Main uses of fused magnesia: fused magnesia is mainly used for alkaline brick, carbon products and amorphous refractories of good raw materials.

2. Low silicon and high calcium fused magnesia products are mainly made of low silicon magnesite as raw material and melted by high temperature electric furnace. It is characterized by a calcium-silicon ratio greater than 2, well-developed grains and a bulk density greater than 3.50g/cm3. Low silicon and high calcium point fused magnesia is mainly used in medium frequency induction furnace melting, high manganese steel, stainless steel, high steel, alkaline brick, carbon products and amorphous refractories of good raw materials.

3, large crystallization fused magnesia production process: large crystallization fused magnesia is mainly the selection of high-grade natural magnesite or high quality high purity light burning magnesium particles, melting in the arc furnace. The product has high purity, large crystal particles, compact structure, strong slag resistance, good thermal shock stability, is an excellent high temperature electrical insulation material, but also the production of magnesia brick, magnesia carbon brick and amorphous refractory material important raw materials. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components and so on.
