MgO-CaO Bricks/magneis clacia brick/magnesia brick rich in CaO

Magnesite-calcium brick is made from high purity and density magnesia and dolomite of synthetic magnesia-dolomite linkers. MgO-CaO bricks are made from high quality magnesite and dolomite as raw materials which are to be processed by two-step burning process MgO/CaO ratio is chosen according to different requirement ,high temperature fining,pitch or paraffin ipmpregnation under vacuum and pressure are adopted in their production, tHEY HAVE VERY GOOD HIGH TEMPERATURE PERFOMANCE AND RESISTANCE TO SLAG,AND ARE APPLICABLE TO THE REFINING UNITS SUCH AS aod FUMACE,VOD fumace cement kiln safety lining and bottom of converter for steelmaking and ladle etc.
