Description of Magnesia Chrome Bricks
Magnesia chrome bricks are magnesia refractories made of magnesium oxide and chromium trioxide as the main components, and magnesite and spinel as the main mineral components. Magnesium-chromium refractory bricks have very strong refractoriness, alkaline erosion resistance and good thermal stability.
Characteristics of magnesia-chrome refractory bricks
High refractoriness
Magnesium-chromium refractory bricks have excellent refractory and high-temperature resistance properties, showing good stability and corrosion resistance at high temperatures, and can be used for a long time in the range of 1100℃-1800℃.
Thermal shock resistance
Magnesia chromium brick has good thermal shock resistance, can withstand rapid changes in temperature, not easy to crack and fracture phenomenon.
Erosion resistance
Magnesia chrome brick has good anti-erosion performance in various corrosive media, strong resistance to alkaline slag erosion, and some adaptability to acidic slag.
Thermal conductivity
Magnesium-chrome bricks have good thermal conductivity, can quickly transfer the required heat to ensure the normal operation of high-temperature devices.
Oxidation resistance
Magnesium chrome brick can resist the occurrence of oxidation reaction, long time use will not appear flaking, slagging and other phenomena.
Application of magnesia-chrome brick
Magnesia chrome brick is a kind of alkaline refractory material, mainly used in metallurgical industry, such as constructing flat furnace roof, electric furnace roof, furnace refining furnace and all kinds of non-ferrous metal smelting furnace. In addition, magnesium-chromium bricks can also be used for masonry cement rotary kiln, glass kiln heat storage room, steelmaking furnace lining, refining ladle permanent layer, lime kiln, iron mixing furnace and refractory high-temperature kiln lining and so on.
