As the basic raw materials of fused rebonded magnesia chrome bricks, synthetic magnesia chromite clinker falls into two types: electricity melting methods and sintering methods.

　　Fused magnesia chrome sand use high purity raw materials such as special grade magnesite, high purity light magnesia or dead burned magnesia, and carefully chosen chrome ore, etc.

　　Magnesia chromite clinker that synthesized by sintering methods use high purity light magnesia and chromium concentrate as raw materials, produced by mixing, compacting, firing in high temperature oil shaft kiln.

　　Fused rebonded magnesia chrome bricks should be fired at 1800～1850℃ ultra-high temperature.

　　Fused rebonded magnesia chrome bricks for lime kiln have features of high purity, less impurities, low apparent porosity, low permeability, high density, high temperature strength, good volume stability.

　　Fused rebonded magnesia chrome bricks as lime kiln refractories can be used for burning zone of rotary lime kiln and calcining zone of shaft lime kiln.
