The above properties are guaranteed values based on the long-term production statistics. Guomei may make the modification upon the production request.
Fused rebonded magnesia chrome bricks adopt fused magnesia and fused magnesia chrome sand as raw materials. Through refined batching, high-pressure forming, and ultra-high-temperature firing, the product has a high direct binding rate, a good degree of particle binding, good high-temperature volume stability, and excellent high-temperature strength, and is widely used in the parts with severe erosion intensity on the smelting furnace, blowing furnace, and refining furnace of non-ferrous smelting industry.
