Fused semi-recombined magnesia-chrome brick
Detailed introduction:


Electrofusion rebondcd electrically fused rnagnesite} hrc} me brick High temperature performance is between fused cast magnesia chrome brick sintered magnesia chrome brick, its load softening temperature can reach 170 (1 C. ',.


Generally, lightly burned magnesia chrome ore are used as raw materials, which are melted in an electric solitary furnace to produce fused magnesia chrome sand, then crushed, ground, compounded, shaped, fired. The application field of this brick is similar to that of ordinary magnesia-chrome bricks


Magnesia-chrome bricks are refractory products with magnesium oxide (MgO) chromium trioxide (Cr2O3) as the main components, periclase spinel as the main mineral components. This type of brick has high fire resistance, high temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, also has certain adaptability to acid slag. The main raw materials for making magnesia-chrome bricks are sintered magnesia chromite. The purity of magnesia raw materials should be as high as possible. The requirements for the chemical composition of chromite are: Cr2O3: 30 to 45%, CaO: ≤ 1.0 to 1.5%.
