[China Aluminum Network] Alumina hollow spheres are mainly used as high-temperature industrial furnace linings below 1800°C, such as high-temperature furnace lining bricks for refractory materials, electronics, and ceramics; thermal insulation layers for high-temperature thermal equipment. For example, petrochemical industrial gasifiers, gasifiers, carbon black reactors, insulation bricks for metallurgical industry induction furnaces. Applications in these areas can save energy by 20% to 30%. This kind of brick is used as the lining of high-temperature kiln, and the temperature rising speed during baking cannot be too fast. Otherwise, it will produce cracks and reduce the strength and service life. Because of its high apparent porosity, it cannot be used for contacting slag, otherwise it will Damaged due to infiltration of molten slag.
