Detailed Description

Mullite Insulating Brick • 1. The product is sintered under high temperature with high— purity raw materials and advanced production technologies. • 2.High pressive strength. • 3. High temperature resistance as well as thermal shock resistance. • 4. It is widely used in the lining of medium-high temperature kilns. Description Mullite insulation bricks are made from good quality and superpure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture. Each grade of products has unique design to meet different thermal, physical and chemical demands. Applications Mullite insulation bricks refractory material can be used in linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc. Physical and chemical index MD serises Brands AL2O3%≥ FE2O3≤ BD G/CM3≤ CCS MPA≥ PLC ℃X H≤1.0% TCS W/M.K≤ 　 　 　 　 　 　 　 　 400℃ 600℃ 900℃ MD-0.5 45 0.8 0.5 2 1350×12 0.18 0.22 0.26 MD-0.6 55 0.8 0.6 2.5 1350×12 0.26 0.3 0.32 MD-0.8 65 0.7 0.8 3 1450×12 0.28 0.32 0.36 MD-1.0 72 0.6 1 4 1450×12 0.3 0.35 0.4 JM series Item JM23 JM26 JM28 JM30 AL2O3(%) 38-44 50-58 65-70 70-73 Fe2O3(%) 1 0.9 0.8 0.7 Classification Temperature (℃) 1350 1430 1540 1600 Bulk Density (g/cm3) 0.8-1 0.8-1 0.8-1 0.8-1 Reheating Linear Change (%) 1250℃ 1400℃ 1500℃ 1550℃ CT-30 ℃X 8H -0.5 -0.5 -0.5 -0.5 Cold Crushing Strength (Mpa) 3.0-4.5 3.0-4.5 3.0-4.5 3.0-4.5 Modulus of Rupture (Mpa) 1.5 1.7 1.8 2 Thermal conductivity400℃(W/m.k) 0.25 0.27 0.32 0.41 Thermal Expansion1000℃(%) 0.5 0.7 0.8 0.9 B C series Item B-1 C-1 C-2 AL2O3(%) 25-30 35-40 45-50 Fe2O3(%) 2 1 1 Classification Temperature (℃) 1000 1300 1400 Bulk Density (g/cm3) 0.8-1 0.8-1 0.8-1 Cold Crushing Strength (Mpa) 2-2.5 2.5-3.5 3.0-4.5 Thermal conductivity400℃(W/m.k) 0.17 0.23 0.25 url:http://www.qs-industry.com
