The fused semi-rebonded magnesia-chrome brick is a basic product made mainly from high-quality fused synthetic magnesia-chrome grain, with part high-purity magnesia, imported chrome concentrate and a small amount of additives, by high-pressure forming and high-temperature firing. It withstands high temperature, erosion, thermal shock and corrosion; its erosion and corrosion resistance are better than those of direct-bonded magnesia-chrome bricks. A basic product of excellent performance, it is especially suitable for the critical areas of all kinds of non-ferrous furnaces.
