Only good raw materials can produce good products - Henan Chongde refractory high alumina bricks. High alumina brick is a refractory material made from bauxite with an alumina content higher than 60%, which is formed under high pressure and sintered at high temperature. It is a common industrial brick, whose main component is aluminum, hence the name "high alumina brick".
The manufacturing process of high alumina bricks is relatively complex, requiring the use of high-quality raw materials such as alumina and silicon. These raw materials undergo high-pressure pressing, high-temperature sintering, and cooling steps to form the porous structure and high-density characteristics of high alumina bricks. During the sintering process, raw materials such as aluminum ore, clay, and limestone are added to the ball mill, which undergoes processes such as ball milling, mixing, and pressing to produce the green body. Then, the green body is sintered to gradually dissolve the aluminum element inside, forming bricks with a certain strength and fire resistance
High alumina bricks have high strength and good thermal stability, and can withstand high temperatures and pressures with high density, strength, and wear resistance. In addition, high alumina bricks also have good oxidation resistance and can be used in high temperature and corrosive environments. However, high alumina bricks also have some drawbacks, such as high prices and high processing difficulty. Therefore, in practical applications, it is necessary to select appropriate materials based on specific needs and budgets.
High alumina bricks have excellent fire resistance, high temperature performance, and thermal shock resistance, and can be widely used in industries such as steel, non-ferrous metals, petrochemical, glass-ceramic, mechanical manufacturing, and other industries. They can also be used in metallurgy, power, manufacturing of electrolytic aluminum, steelmaking furnace lining, blast furnace bottom, and other high-temperature materials. In the field of electricity, high alumina bricks can be used to make high-temperature equipment such as electric furnaces and blast furnaces, as well as to make wires and cables. With the continuous development of science and technology, the application fields and performance of high alumina bricks will continue to be improved and optimized, bringing more convenience and possibilities to our production and life. Overall, high alumina bricks are a material with broad application prospects, but attention should be paid to material selection and environmental protection issues in use.

The price of high alumina bricks is influenced by various factors, such as quality, type, specifications, market supply and demand, etc. Here are some reference information:
