Corundum Mullite Brick
Corundum mullite brick has excellent high temperature mechanical properties and thermal shock stability, and is widely used in petrochemical equipment such as sulfur burning furnaces, waste heat boilers, and exhaust gas burning furnaces. The lining material for sulfur recovery unit jointly developed by our company and Qilu Petrochemical Refinery Design Institute adopts internal masonry and external pouring structure, which has the advantages of strong acid gas corrosion resistance, high temperature and high strength, stable structure and convenient construction. The design obtained the "utility model patent certificate" (patent number: ZL 2007 2 0030D13.9).
