The direct bonded magnesia chrome brick refers to the product fired by the lower impurity content of chromium ore and the purer magnesia, at the temperature of 1700℃ above. Good slag resistance and high temperature performance, good thermal shock resistance.
The Direct bonded magnesia chrome brick price reasonable, high strength of high-temperature structure, high softening temperature under load and strong resistance to chemical erosion. It is mainly used in cement rotary kiln, electric lining of steelmaking furnace, refining furnace (rh upper groove, lower groove permanent lining, vod furnace wall), non-ferrous metallurgy furnace, heat storage room of glass kiln, lime kiln, mixed iron furnace, etc.
Magnesia chrome brick refractory products with magnesium oxide (mgo) and chromium trioxide (cr2o3) as the main components and magnesite and spinel as the main mineral components. This kind of brick has high fire resistance, high temperature strength, strong resistance to alkaline slag erosion, good thermal stability, and certain adaptability to acid slag. The main raw materials of magnesia- chrome brick are sintered magnesia and chromite.
The Direct bonded magnesia chrome brick price cheap, is mainly used in metallurgical industry, such as construction of open hearth furnace top, electric furnace top, refining furnace outside the furnace and various non-ferrous metal smelting furnace. The high temperature part of the wall of the ultra-high power electric furnace is made of fused cast magnesia-chrome bricks, the high erosion area of the refining furnace outside the furnace is made of magnesia-chrome bricks made of synthetic materials, and the high erosion area of the flash melting furnace of non-ferrous metals is made of fused cast magnesia-chrome bricks and magnesia-chrome bricks made of synthetic materials.
