High aluminum insulation brick
The lightweight high-alumina insulation brick is made of bauxite as the main raw material, and the insulating refractory brick with Al2O3 content of not less than 48%. High-aluminum heat-insulating refractory bricks, mainly made of bauxite clinker, combined with clay as raw material, incorporating binder and sawdust, in order to improve product performance, add industrial alumina, corundum, sillimanite, kyanite, silica Fine powder. A product having a bulk density of 0.4 g/cm3 or more can be obtained. Al2O3 content and bulk density are different, and the higher use temperature is also different, usually between 1250 and 1350 ° C, and some can reach 1550 ° C. Regarding the price of lightweight high-alumina insulation bricks, the main influencing factors are the size, quantity and physical and chemical indicators of lightweight high-alumina bricks.
Standard for alumina hollow ball insulation refractory brick
The alumina hollow sphere products are sintered at high temperature with high-purity alumina hollow spheres as the main raw material. The products have the advantages of small bulk density, high compressive strength, low thermal conductivity and high use temperature. They can be widely used in synthetic ammonia liquefaction furnaces, ethylene production. The lining of a high-temperature kiln such as a gas furnace has strong resistance to corrosive gases and slag, and the use temperature is below 1800 °C.
