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, tiết kiệm năng lượng, 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, giảm tản nhiệt, và cải thiện hiệu suất nhiệt, 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, Gạch chịu lửa, vân vân. High-purity alumina balls are widely used in high-temperature and ultra-high-temperature kilns, lò đưa đón, lò dây molypden, lò nung que vonfram, lò cảm ứng, and nitriding furnaces such as gasifiers in the petrochemical industry, carbon black industrial reactors, and induction furnaces in the metallurgical industry. Application, significant results have been achieved in reducing the weight of the furnace body, chuyển đổi cấu trúc, tiết kiệm vật liệu, và tiết kiệm năng lượng.

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: lên đến 1750 degrees or more, ổn định nhiệt tốt. The reheat line has a small change rate and can be used for a longer period.
2. Tối ưu hóa kết cấu và giảm trọng lượng của lò: 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. Tiết kiệm vật liệu: To achieve the same operating temperature, nếu gạch nặng được sử dụng, 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, Và 80% of refractory insulation materials can be saved.
4. Tiết kiệm năng lượng: Bóng rỗng Alumina có đặc tính cách nhiệt rõ ràng và độ dẫn nhiệt thấp, which can have a good thermal insulation effect, giảm tản nhiệt, và cải thiện hiệu suất nhiệt, thereby saving energy. The energy-saving effect can reach more than 30%.
