Magnesia Chrome Brick Introduction：
Magnesia chrome bricks are refractory products with magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components.
Features & Benefits of Magnesia chrome bricks：
1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable for various atmosphere.
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely.
4. Product specification: standard form, normal standard, shaped and special shaped bricks.
Ordinary Magnesia Chrome Brick:
Magnesia chrome bricks have high refractoriness, strong corrosion resistance to alkaline slag, and good thermal shock resistance. At the same time, magnesia chrome bricks also have a certain
degree of adaptability to acid slag and anti-stripping properties.

Direct-bonded Magnesia Chrome Brick
Due to the low impurity of the raw materials and the direct bonding between the crystal phases, direct-bonded magnesia chrome brick has the characteristics of low porosity, high crushing
strength, strong wear resistance, corrosion resistance, thermal shock resistance, and anti-stripping.

Direct-bonded Magnesia Chrome Brick
Semi-rebonded Magnesia Chrome Brick
Semi-reboned magnesia chrome bricks have the characteristics of compactness, low porosity and high strength at high temperatures. Its thermal shock resistance is better than rebonded
magnesia chrome bricks. What is more, it has strong resistance to slag erosion.

Fused Reboned Magnesia Chrome Brick
Magnesia chrome brick Application:
Molten magnesia chrome bricks are used at the high temperature part of the furnace wall of the ultra high power electric furnace, magnesia chrome bricks made of synthetic materials are used in
the high erosion area of the external refining furnace, and magnesia chrome bricks made of molten magnesia chrome bricks and synthetic materials are used in the high erosion area of the non
ferrous Flash smelting furnace. In addition, magnesium chromium bricks are also used in areas such as the firing zone of cement rotary kilns.
