Magnesia Chrome Brick

Magnesite spinel bricks are refractory bricks made from a combination of magnesite (MgO) and spinel (MgAl2O4) minerals. These bricks are used in high-temperature applications where excellent thermal and chemical resistance is required, such as in the lining of steelmaking furnaces, cement kilns, and other industrial furnaces.

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. This type of brick has high refractory resistance, high high-temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and certain adaptability to acidic slag. The main raw materials for manufacturing magnesia chrome bricks are sintered magnesia and chromite

Magnesia iron spinel brick is a new generation of alkaline refractory with more technical content. It is mainly used in the firing zone of large dry process cement kiln. The microstructural characteristics of magnesia-aluminum spinel are relatively complex, mainly a combination of magnesia microstructure and iron-aluminum spinel microstructure. The interface between magnesia and iron-aluminum spinel is formed by Mg2+, Al3+, Fe2+ ions. The mutual diffusion and close combination realize the direct combination of materials.
