Огнеупорные пузырьковые шарики из глинозема

Refractory bubble alumina balls are a new type of high-temperature insulation material. Refractory bubble alumina balls are made of industrial alumina as raw material and are melted and blown in an electric furnace. Alumina hollow balls can be used as high-temperature and ultra-high-temperature insulation fillers.

What are alumina balls?

Alumina hollow balls and their products are lightweight refractory materials that are high temperature resistant, сохранение энергии, environmentally friendly, and very stable in various environments. Alumina balls have obvious thermal insulation properties and low thermal conductivity, which can have a good thermal insulation effect, уменьшить тепловыделение, и повысить тепловую эффективность, thereby saving energy. The energy-saving effect can reach more than 30%. It is especially suitable for use in high-temperature furnaces of 1800℃.

Application of high-purity alumina balls

High-purity alumina balls can be used as high-temperature and ultra-high-temperature insulation fillers, high-temperature refractory concrete lightweight aggregates, high-temperature castables, огнеупорный кирпич, и т. д.. High-purity alumina balls are widely used in high-temperature and ultra-high-temperature kilns, челночные печи, печи с молибденовой проволокой, печи с вольфрамовыми стержнями, индукционные печи, and nitriding furnaces such as gasifiers in the petrochemical industry, carbon black industrial reactors, and induction furnaces in the metallurgical industry. Приложение, significant results have been achieved in reducing the weight of the furnace body, преобразование структуры, экономия материалов, и экономия энергии.

What are alumina hollow ball bricks?

Alumina hollow ball bricks Use alumina balls as the main body, they can be made into products of various shapes. The maximum operating temperature is 1800°C. The mechanical strength of the products is high, several times that of ordinary lightweight products, and the volume density is only one-half of corundum products. It is widely used in high-temperature and ultra-high-temperature kilns.

Advantages of refractory bubble alumina balls

1. High operating temperature: до 1750 degrees or more, хорошая термическая стабильность. The reheat line has a small change rate and can be used for a longer period.
2. Оптимизируйте конструкцию и уменьшите вес печи: the bulk density of high-temperature-resistant bricks currently used are heavy bricks of 2.6-3.0g/cm, while alumina hollow ball bricks are only 1.1-1.5g/cm. For the same cubic meter volume, Using alumina hollow ball bricks can save 1.1-1.9 tons of weight.
3. Сохраняйте материалы: To achieve the same operating temperature, если используется тяжелый кирпич, the price is equivalent to that of alumina hollow ball bricks, and a considerable amount of insulation layer refractory materials are also required. If alumina hollow ball bricks are used, 1.1-1.9 tons of heavy bricks can be saved per cubic meter, и 80% of refractory insulation materials can be saved.
4. Энергосбережение: Полые шарики из оксида алюминия обладают очевидными теплоизоляционными свойствами и низкой теплопроводностью., which can have a good thermal insulation effect, уменьшить тепловыделение, и повысить тепловую эффективность, thereby saving energy. The energy-saving effect can reach more than 30%.
