Fused cast magnesite-chrome brick
Description:
The fused-cast magnesite-chrome brick has a peculiar resistance to the damage of slag penetration. Since it is a dense frit made by melting, pouring and cooling, the slag can only be eroded on the outside of the brick without a large number of signs of osmotic (this has been proved by the section of the cast magnesite-chrome brick after use). Although magnesite-chrome brick is difficult and expensive to produce, it is still used in the key parts of non-ferrous smelting furnaces in developed countries, and it has an irreplaceable role in other refractory materials.
Advantages:
Dense,
large pores and isolated, high strength, corrosion resistant, good
thermal shock to resistance, high refractoriness under load
Application:
Slag ingress, corrosion, wear and erosion area, non-ferrous metal smelting flash furnace reaction tower side wall and sedimentation tank slag line parts, continuous operation furnaces
