Description

Description of 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.

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

Fused rebonded magnesia chrome brick is a high-grade refractory product with excellent corrosion resistance. The performance at high temperature is between that of fused magnesia chrome brick and sintered magnesia chrome brick.
