Product Description

High Mechanical Strength Bubble Alumina Insulation Brick Used in Metallurgical

High Mechanical Strength Bubble Alumina Insulation Brick Used in Metallurgical for insulation layer is a new type of high-temperature insulation material, which is made by melting and blowing industrial aluminum oxide in an electric furnace. With aluminum oxide hollow balls as the main body, various shaped products can be made. The product has a high operating temperature of 1800 ℃, high mechanical strength, several times that of ordinary lightweight products, and a volume density only half of that of corundum products. High Mechanical Strength Bubble Alumina Insulation Brick Used in Metallurgical are widely used in high-temperature and ultra-high temperature kilns such as gasification furnaces in the petrochemical industry, carbon black industrial reaction furnaces, and induction electric furnaces in the metallurgical industry, and have achieved very good energy-saving effects.

High Mechanical Strength Bubble Alumina Insulation Brick Used in Metallurgical

1. High usage temperature: It can reach above 1750 degrees and has good thermal stability. The rate of change of the re burned line is small, and it can be used for a longer time. 2. Optimize the structure and reduce the weight of the furnace body: Nowadays, high-temperature resistant materials are commonly used as heavy bricks with a volume density of 2.6-3.0g/cm, while alumina hollow ball bricks only have a volume of 1.1-1.5g/cm. With the same cubic meter volume, using alumina hollow ball bricks can reduce weight by 1.1-1.9 tons. 3. Material saving: To achieve the same operating temperature, the price of using heavy bricks is comparable to that of alumina hollow ball bricks, and a considerable amount of insulation layer refractory material is also required. If alumina hollow ball bricks are used, it can save 1.1-1.9 tons of heavy bricks per cubic meter, and also save 80% of refractory insulation materials. 4. Energy saving: Aluminum oxide hollow balls have obvious insulation properties and low thermal conductivity, which can achieve good insulation effect, reduce heat dissipation, improve thermal efficiency, and thus save energy. The energy-saving effect can reach over 30%.

Manufacture Specification

High Mechanical Strength Bubble Alumina Insulation Brick Used in Metallurgical

High Mechanical Strength Bubble Alumina Insulation Brick Used in Metallurgical is a type of ultra-high temperature energy-saving and insulation material, which is mainly made of aluminum oxide hollow balls and aluminum oxide powder, combined with other binders, and fired at a high temperature of 1750 degrees. Aluminum oxide hollow ball brick is a new type of high-temperature insulation material, which is made by melting and blowing industrial aluminum oxide in an electric furnace. With aluminum oxide hollow balls as the main body, various shaped products can be made. The product has a high operating temperature of 1800 ℃, high mechanical strength, several times that of ordinary lightweight products, and a volume density only half of that of corundum products. Aluminum oxide hollow ball bricks are widely used in high-temperature and ultra-high temperature kilns such as gasification furnaces in the petrochemical industry, carbon black industrial reaction furnaces, and induction electric furnaces in the metallurgical industry, and have achieved very good energy-saving effects. Aluminum oxide hollow balls and their products are lightweight refractory materials with high temperature resistance and excellent energy conservation, which are very stable when used in various atmospheres. Especially suitable for application in high-temperature kilns at 1800 ℃. Hollow balls can be used as high-temperature and ultra-high temperature insulation fillers, lightweight aggregates for high-temperature refractory concrete, high-temperature pouring materials, etc. Hollow ball bricks can be used for high-temperature energy-saving (>30%) inverted flame kilns, shuttle kilns, molybdenum wire furnaces, tungsten rod furnaces, induction furnaces, nitriding furnaces, etc. Significant results will be achieved in reducing the weight of the furnace body, transforming the structure, saving materials, and energy. Aluminum oxide powder is produced using reliable industrial aluminum oxide as raw material, using a new high-temperature inverted flame kiln and scientific calcination process. It is manually selected, graded clearly, contains less impurities, has high conversion rate, stable shrinkage rate, and good consistency.
