Do you know these properties of magnesia bricks?

The microstructure of magnesia bricks is actually a combination of magnesia microstructures. The microstructure of the magnesia brick made of a magnesia is the simplest, except that the matrix part is loose and the pores are more. Magnesia bricks made of different grades of magnesia have obvious differences in their microstructure. Magnesia bricks made of magnesia with high impurity content have many silicate phases, and the MgO crystals are round and the direct bonding rate is low. The content of impurities in raw materials is small, and the magnesia bricks with ultra high temperature firing are reduced, the silicate is reduced, and the direct bonding rate is high. In the magnesia bricks with the MgO content of 98% or more, the MgO crystals are self-shaped and semi-automorphic. True intergranular direct bonding is only possible in materials that do not contain silicates and intercrystalline pores.
The performance of magnesia bricks varies greatly depending on the raw materials, production equipment and process measures.
Made of fused magnesia as raw material, it has high strength, high temperature resistance and good chemical stability.
Basic slag resistance, high refractoriness, good thermal stability, excellent corrosion resistance and flaking resistance
Pressure bending excellent strength, wear resistance
Excellent performance at high temperature firing, high Lenovo property rate and corrosion resistance
Excellent thermal shock resistance and flaking resistance
High refractoriness and excellent resistance to corrosion of alkaline slag;
High temperature load under refractoriness load. High mechanical strength
High temperature resistance and excellent corrosion resistance
Because of its high temperature performance and strong resistance to metallurgical slag, magnesium brick is widely used in steel industry lining, iron alloy furnace, mixed iron furnace, colored industrial furnace, copper, lead, tin, zinc lining building industry lime burning kiln; glass Industrial regenerator grids and civil heat exchangers; high temperature calcining kiln for refractory industry, such as high temperature shaft kiln for calcining magnesia, high temperature tunnel kiln for burning alkaline refractory bricks, etc.
