Industry Knowledge of Magnesia Chrome Brick

Magnesia chrome brick is a kind of basic refractory material made from magnesia and chrome ore as the main raw materials. It is widely used in various high-temperature kilns, furnaces and other thermal equipment due to its excellent corrosion resistance and high-temperature resistance.

Classification:
According to the content of chrome oxide, magnesia chrome bricks can be divided into ordinary magnesia chrome bricks (with a chromium oxide content of less than 10%) and high chromium magnesia chrome bricks (with a chromium oxide content of more than 10%). In addition, according to different production processes and application requirements, magnesia chrome bricks can also be divided into sintered magnesia chrome bricks, direct bonded magnesia chrome bricks, and fused magnesia chrome bricks.

Technical Parameters:
The performance of magnesia chrome bricks is mainly determined by the content of magnesia and chrome oxide, the porosity, the apparent density, and the compressive strength. The higher the content of magnesia and chrome oxide, the better the performance of the brick. The lower the porosity, the higher the apparent density, and the better the compressive strength, which indicates that the brick has better resistance to thermal shock and mechanical shock.

Production Process:
The production process of magnesia chrome bricks includes raw material preparation, mixing, molding, drying, firing, and packaging. The specific production process is different for different types of magnesia chrome bricks. For example, sintered magnesia chrome bricks are produced by mixing the raw materials, molding them under high pressure, and firing them at a high temperature; while fused magnesia chrome bricks are produced by melting the raw materials and casting them into molds.

In conclusion, magnesia chrome bricks play an important role in the field of refractory materials. With the development of new technologies, the performance and application fields of magnesia chrome bricks will continue to expand and improve.
