Description
Fused rebonded magnesia chrome brick is generally made by first melting lightly burned magnesia and chromite in an electric arc furnace to produce fused magnesia-chrome sand. Then this sand is crushed, ground, proportioned, shaped and sintered to manufacture the final product. These bricks have a high degree of direct bonding, low impurity content, resulting excellent high-temperature strength, superior high-temperature volume stability, as well as outstanding corrosion and erosion resistance.
