Sell CN ZS Refractory Magnesite Bricks

Product Description                                         1. Product Details Magnesia-chrome brick is a high-level refractory product material ,which containing MgO and Cr2O3 as the main components, periclase and spinel are the main mineral components. This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag, excellent thermal stability, and certain adaptability to acidic slag. The main raw materials for the manufacture of magnesia chrome bricks are sintered magnesia and chromite. The purity of the magnesia raw material should be as high as possible.  2.Features (1).high refractoriness (2).high temperature strength (3).strong resistance to alkaline slag (4).excellent thermal stability 3.Technical Data Commom Magnesite Chrome Brick Chemical composition and technical performance  Product brand   SRMG-8  SRMG-12  SRMG-15  SRMG-18  MgO(%)  ≥65  ≥60  ≥55  ≥52  Cr2O3(%)  ≥8  ≥12  ≥15  ≥18  SiO2(%)  ≤1.5  ≤1.5  ≤1.8  ≤1.8  Apparent porosity(%)  ≤18  ≤18  ≤18  ≤18  Cold crushing strength(MPa)  ≥40  ≥40  ≥40  ≥40  0.2MPa refractoriness under load T0.6(oC)  ≥1670  ≥1670  ≥1670  ≥1670  Thermal shock resistance(1300oC air cooling)(1100oC water cooling)  ≥30≥6  ≥30≥6  ≥30≥6      Fused Magnesite Chrome Brick Chemical composition and technical performance Product brand    ERMG-12 ERMG-16 ERMG-20 MgO(%) ≥60 ≥55 ≥50 Cr2O3(%) ≥12 ≥16 ≥20 SiO2(%) ≤1.5 ≤1.8 ≤2.0 Apparent porosity(%) ≤16 ≤16 ≤16 Cold crushing strength(MPa) ≥40 ≥40 ≥40 0.2MPa refractoriness under load T0.6(oC) ≥1700 ≥1700 ≥1700 Thermal shock resistance(1300oC air cooling)(1100oC water cooling) ≥15≥4 ≥15≥4 ≥15≥4
