Buy Refractory Brick Corundum bricks refer to refractory products with alumina content greater than 90% and corundum as the main crystal phase. High normal temperature compressive strength (up to 340MPa). High load softening starting temperature (greater than 1700 鈩?. Very high Good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid, etc. Thermal shock stability is related to its structure, compact products have good corrosion resistance, but poor thermal shock stability .Corundum bricks can be divided into sintered corundum bricks and fused corundum bricks according to the basic materials used. In order to better meet the needs of the kiln, other chemical mineral components are usually added in the production process of corundum bricks to form composite products, such as zirconium corundum bricks, chrome corundum bricks, etc. The advantages of corundum brick 1. It has good sintering activity and can improve the density of corundum bricks; 2. The corundum brick of tabular corundum has high bulk density and low apparent porosity; 3. Has high normal temperature compressive strength, normal temperature flexural strength and high temperature flexural strength; 4. Good wear resistance Chemical and physical of properties Item BrandCorundum container, tube and ballBrick, u-shaped tube etc Pure CorundumTitanium CorundumChrome CorundumZirconia CorundumThermocouple PipeCorundum ballCorundum bricksTitanium bricksSpecial shape Al2O3%鈮?8.5鈮?7.0鈮?7.080-65鈮?8.5鈮?8.5鈮?8.5鈮?7.090-98.5 SiO2%鈮?.5鈮?.5鈮?.5 鈮?.5鈮?5鈮?.4鈮?.5 Fe2O3%鈮?.3鈮?.4鈮?.5 鈮?3鈮?.3鈮?.3鈮?.4 TiO2% 鈮?8鈮?.8 Gr2O3% 鈮?.2 ZrO2% 16-35 K2O%鈮?.2鈮?.3鈮?.3 鈮?.2鈮?.2 Other impurity %鈮?.4鈮?.5鈮?.5 鈮?.4鈮?.4 Bulk density g/cm3鈮?.6鈮?.6鈮?.6 鈮?.6鈮?.6鈮?9鈮?.0鈮?.9 Apparent porosity %鈮?鈮?鈮? 鈮?鈮?20-2620-25鈮?8 Cold crushing strength MPa鈮?00鈮?00鈮?00 鈮?00鈮?00鈮?0鈮?5鈮?5 Rerfactoriness under load KD 鈩?/p>鈮?700鈮?700鈮?700 鈮?700鈮?700鈮?700鈮?700鈮?700 Thermal shock resistance 1100鈩?water cooling cycles 鈮?鈮?鈮?
