Magnesia chrome brick

Magnesia chrome bricks are refractory products with magnesium oxide (MgO) and chromium trioxide (Cr₂O₃) as the main components, and periclase and spinel as the main mineral components. It has high refractoriness, strong resistance to alkaline slag erosion, good thermal stability, and certain resistance to acidic slag.

Magnesia chrome bricks are alkaline refractory products, generally produced from sintered magnesia (MgO content between 89% and 92%) and refractory grade chromium bricks. Due to many impurities, the refractory grains are bonded with silicate. Also known as silicate-bonded magnesia-chromium bricks, or magnesia-chromium bricks for short.
Magnesia-chromium bricks are made of periclase and magnesia-chromium spinel as the main crystal phases. They are fired at 1600~1800℃ in an oxidizing atmosphere. They can also be made into unfired bricks with chemical binding agents such as water glass.
Features of magnesia chrome bricks:
The refractoriness is greater than 2000°C, the load softening temperature is generally above 1550°C, the high temperature volume stability is good, and the resistance to rapid cooling and rapid heating is good.
Application areas of magnesia chrome bricks:
Mainly used in cement rotary kilns, glass kiln regenerators, steelmaking furnace linings, refining ladle permanent layers, non-ferrous metallurgical furnaces, lime kilns, iron mixing furnaces and refractory high-temperature kiln linings, etc.
Supports custom-made magnesia-chrome bricks of various brick types, and can be customized according to drawings.

Magnesia chrome brick product application:

Magnesia chrome bricks produced by Anshan Justhigh New Material Development Co., Ltd. are mainly used in cement rotary kilns, glass kiln regenerators, steelmaking furnace linings, refining ladle permanent layers, non-ferrous metallurgical furnaces, lime kilns, iron mixing furnaces and refractory Materials for high temperature kiln lining, etc. Kerui adjusts the performance of the products in the production environment according to different parts and temperature requirements of each thermal kiln. At the same time, special-shaped bricks are used in complex parts to take into account the economic benefits of the enterprise and subsequent maintenance needs.
