Refractory Bubble Alumina Ball (also called Refractory Hollow Alumina Ball, or Sphere Alumina Refractory), Bubble Alumina balls and likely products are light refractories with high temperature resistance and excellent energy saving, which are very stable in various atmospheres.
Calcined Kaolin Material (also called Kaolin Clay or Chamotte) is an essential industrial mineral primarily made up of the mineral kaolinite – a hydrous aluminum silicate. Kaolin can be found in applications all around us, from consumer products, to advanced industrial processing.
High Alumina Raw Materials (also called bauxite or flint clay) are used to improve the performance of refractories by imparting properties such as strength, protection from chemical and physical attack, and slag resistance.
Corundum brick is a high-temperature refractory material whose main component is alumina. Corundum is a crystal structure formed from aluminum oxide that is highly hard and wear-resistant. Corundum bricks can be divided into several main categories based on other ingredients and uses in corundum bricks: Ordinary corundum bricks: The main component is alumina and does not contain other special additives. This type of corundum brick is usually used in general high-temperature fire-resistant situations. Zirconium corundum bricks: Add a certain amount of zircon stone to alumina to improve the fire resistance and thermal shock stability of corundum bricks. This kind of corundum brick is suitable for harsh high-temperature process conditions. Chrome corundum bricks: Adding a certain amount of chromium oxide to alumina can improve the corrosion resistance of corundum bricks and is suitable for some high-temperature environments with corrosive atmospheres. Silicon carbide corundum brick: Silicon carbide is added to corundum brick to improve its wear resistance and impact resistance. This kind of corundum brick is often used in some industrial situations that require high wear and impact. Mullite corundum bricks: Adding an appropriate amount of mullite to corundum bricks can improve their slag resistance and thermal shock resistance. The classification of...
The choice of T3 clay bricks or high alumina bricks for the kiln depends on many factors, including the kiln’s usage environment, process requirements, budget, and required fire resistance. Usage environment: If the working temperature of the kiln is high and there are high-temperature heat and chemical corrosive substances, such as metal smelting furnaces, glass kilns, etc., it may be more suitable to choose high alumina bricks, because high alumina bricks have better performance at high temperatures: thermal shock resistance and corrosion resistance. If the kiln operates at a lower temperature and does not require particularly high fire resistance, such as a brick kiln, etc., T3 clay bricks may be a more economical and suitable choice. Process requirements: If the process in the kiln requires special treatment of the product, such as high-temperature calcination, chemical reaction, etc., the stability and durability of the material need to be considered. In this case, high-alumina brick may be more suitable because of its higher resistance to thermal shock and erosion. If the process requirements in the kiln are not high and only general firing or heating is performed, T3 clay bricks may be a more economical and suitable choice. Budget: Considering budget factors,...
Aluminum chromium amorphous refractory materials for plasma incinerators This technology uses thermal spraying technology to spray it directly to the surface of aluminum chromium bricks to protect the aluminum chromium bricks of the furnace wall from further eroded, which greatly extends the service life of the refractory material of the working layer, improves the plasma incineration furnace, work rate.

White corundum is a high-purity alumina ceramic material. Its production process usually includes the following steps: Raw material preparation: Select high-purity alumina powder as raw material. These alumina powders are usually prepared by chemical methods, metallurgical methods, or high-temperature calcination methods. Ingredients and Mixing: The selected alumina powders are mixed in specific recipe proportions. During the mixing process, some auxiliaries or additives, such as binders, thickeners, etc., can be added to improve the molding performance and processing performance of the material. Molding: The mixed powder material is passed through a molding process, such as pressing, injection molding, or extrusion molding, to form a white corundum body with the required shape and size. The choice of molding method often depends on application requirements and product design. Sintering: After the white corundum body is formed, it needs to be sintered at high temperatures. During the sintering process, the white corundum body is placed in a high-temperature environment, usually between 1900°C and 2200°C, for continuous heat treatment. During this process, alumina powder particles are combined and rearranged to form a dense structure. Finishing and surface treatment: The sintered white corundum body can be finished and surface treated, such as cutting, grinding, polishing, etc.,...
Inorganic insulation materials can be used to replace fiber products for kiln insulation. Inorganic thermal insulation materials are a type of material with excellent thermal insulation properties in high-temperature environments. They are usually made of inorganic minerals, such as alumina, silicon oxide, magnesium oxide, etc. Compared with fiber products (such as refractory fibers), inorganic thermal insulation materials have some advantages and applicability, such as: High-Temperature Resistance: Inorganic insulation materials are generally able to withstand higher temperatures because they are composed of inorganic minerals that are resistant to high temperatures. Resistance to vibration and mechanical stress: Due to their hard nature, inorganic insulation materials have better resistance to vibration and mechanical stress and are suitable for some environments that require higher durability. Resistance to chemical corrosion: Inorganic insulation materials have good resistance to chemical corrosion and can be used in some applications involving corrosive gases or chemicals. Stability: The performance of inorganic thermal insulation materials is relatively stable under long-term high temperatures and is not prone to pyrolysis, decomposition, or reduction of thermal insulation performance. However, some issues need to be noted Weight: Inorganic insulation materials are generally dense and relatively heavy. This may affect the design of some applications. Thermal...
