Properties and characteristics of magnesia-chrome bricks

Magnesia-chrome brick is a refractory product composed of magnesia (MgO) and chromium trioxide (Cr2O3) as the main components, with periclase and spinel as the main mineral components, and belongs to alkaline refractory products. This type of brick has high fire resistance, high temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and also has certain adaptability to acid slag. Magnesia-chrome bricks are generally fired with light-burned magnesia and imported chromium ore, also known as ordinary sintered magnesia-chrome bricks, referred to as magnesia-chrome bricks.
 

The firing process of magnesia-chrome bricks is similar to that of magnesia bricks.

Magnesium chrome brick features:

Fire resistance is greater than 2000 ℃, load softening temperature is generally above 1550 ℃, good volume stability at high temperature, good resistance to rapid cooling and rapid heating.

 

Magnesia-chrome brick application areas:

Mainly used in cement rotary kiln, glass kiln heat storage chamber, steelmaking furnace lining, refining ladle permanent layer, non-ferrous metallurgy furnace, lime kiln, iron-mixing furnace and refractory high-temperature kiln lining, etc. Furnace tops, refining furnaces outside the furnace, and various non-ferrous metal smelting furnaces.
