Magnesia Brick

Brand:MZ-91

Description:Magnesia Brick Features: Excellent performance of basic slag resistance, high refractoriness, thermal stability, anti-erosion and anti-peeling Excellent strength of pressure bending, abrasion proof Excellent performance of high-temperature firing, high rates of associative property, anti-erosion ability Excellent thermal shock resistance and spalling resistance Excellent ability of high refractoriness, anti-erosion of alkaline residue; High temperature load of refractoriness under load. High mechanical strength High temperature resistance excellent corrosion resistance Resistance to spalling It is basic refractory which the main phase is periclase. The product has such characteristics as high temperature resistance. Good slag resistance. strong corrosion resistance and steady volume in high temperature.

Origin:China Henan
