Corundum mullite brick


Corundum mullite brick has excellent high temperature mechanical properties and thermal shock stability, and is widely used in sulfur combustion furnaces, waste heat boilers, exhaust gas combustion furnaces and other petrochemical equipment. The lining material for sulfur recovery unit jointly developed by our company and Qilu Petrochemical Refinery Design Institute adopts an inner building and an outer casting structure, which has the advantages of strong acid gas erosion resistance, high temperature and high strength, stable structure and convenient construction. The design has obtained the "Utility Model Patent Certificate" (Patent No.: ZL 2007 2 0030D13.9).
