High-alumina refractory bricks are made from bauxite or kaolinitic clays. The definition high-alumina refractory bricks contain between 50 and 87.5 percent alumina. They are much harder and tougher than fireclay refractories at high temperatures and in basic environments.

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.
Concrete is an important building material, and there are many types of it. As two of them, heat-resistant concrete and ordinary concrete are both building materials, but there are great differences in their uses and characteristics. Today, I will briefly introduce the difference between the two. 1. Different composition The composition of heat-resistant concrete mainly includes heat-resistant gelling materials, heat-resistant aggregates, and refractory cement, which is highly resistant to high temperatures. Ordinary concrete is generally made of cement, coarse aggregate (crushed stone or pebbles), fine aggregate (sand), admixtures, etc. The composition of the raw materials between the two is very different. The raw materials of heat-resistant concrete have certain fire resistance, while ordinary concrete does not. 2. Different characteristics Heat-resistant concrete can be used stably at high temperatures of 200-1300℃. For some high-quality heat-resistant concrete, the heat-resistant temperature can reach 1500℃, and the volume density is 2.1-2.15g/cm3. In addition, it has high strength and wear resistance during use. The compressive strength of heat-resistant concrete is generally 10-40MPa, and the high-temperature strength is 3.5MPa-20MPa, so it can maintain high strength even at high temperatures. Ordinary concrete does not have a very high heat resistance temperature. Usually, after it exceeds 300℃, its...
The heat storage balls in melting furnaces play a vital role in the melting process, and their role is mainly reflected in the following aspects: 1. Heat storage and reuse As a key component in the melting furnace, the main function of the heat storage ball is to absorb and store the heat released by high-temperature gas or liquid. This heat can then be released when needed to preheat the air or fuel entering the melting furnace, thereby improving the utilization rate of thermal energy. This heat storage and reuse mechanism helps to reduce energy consumption and improve melting efficiency. 2. Optimize the melting environment Since the heat storage ball can absorb high-temperature heat, it also helps to stabilize the temperature field in the melting furnace and reduce the impact of temperature fluctuations on the melting process. A stable melting environment helps to improve the quality of the smelting product and reduce the defective rate. In addition, the heat storage ball can also reduce the exhaust gas emissions generated during the melting process to a certain extent and improve environmental protection performance. 3. Enhance heat exchange efficiency The heat storage ball is usually made of high-temperature and corrosion-resistant refractory materials,...
Anti-permeability castables are mainly used in various industrial and civil building structures that require high strength, high wear resistance, and high anti-permeability performance. This material plays an irreplaceable role in many fields due to its unique anti-permeability performance. First of all, in the field of industrial production, anti-permeability castables are widely used in equipment foundations and structures in metallurgy, chemical industries, building materials, and other industries. For example, in the foundation parts of key equipment such as blast furnaces, hot blast furnaces, and converters in the metallurgical industry, because they need to withstand high temperatures, heavy loads, and complex chemical reaction environments, castables with high anti-permeability, high strength, and high stability must be used to ensure the safe operation of the equipment. Similarly, in the chemical industry, the bottoms and connecting parts of various storage tanks, reactors, and other containers also need to use anti-permeability castables to prevent the penetration and corrosion of chemical media and ensure the continuity and safety of the production process. Secondly, in the field of civil construction, anti-permeability castables also play an important role. Especially in humid environments such as basements, toilets, and pools, traditional building materials often find it difficult to meet the requirements...
Steel fiber reinforced corundum and high-alumina refractory castables for rotary kiln mouths are prone to cracking and peeling after many years of use, that is, poor thermal shock resistance and low service life. It is well known that clay bricks are better than high-alumina bricks in thermal shock resistance and alkali resistance because of low aluminum content; high strength, good wear resistance, and poor shock resistance. In the castables for kiln mouths, the Al2O3 content is 50% to 70%, the strength is moderate (taking into account both wear resistance and suitable thermal shock resistance), and the drying and compressive strength (1100℃) are about 40MPa and 70MPa respectively. It should be pointed out that refractory castables are composed of aggregates, powders, binders, and admixtures (substances). The phase composition in the matrix is in a non-equilibrium state before use. When used under high temperatures, the components in the matrix will follow the phase equilibrium relationship to re-form a new phase equilibrium (that is, obtain excellent performance and in-situ reaction). Therefore, suitable component materials should be selected and the batch design should be optimized to achieve good sinterability, volume stability, corrosion resistance, and high-temperature mechanical properties. Selection of main materials The front kiln...
As a high-performance refractory material, chrome corundum bricks are mainly used in industrial fields that need to withstand high temperatures, high pressures, and corrosive environments. Their excellent fire resistance, flexural strength, high-temperature creep, high-temperature volume stability, and corrosion resistance make them a key component in many industrial furnaces. The following are the main areas of application of chrome corundum bricks: 1. Metallurgical industry Steel smelting: Chromium corundum bricks are widely used in rolling heating furnaces in the steel industry, especially in parts prone to wear such as slide rails, tapping channels, and grooves. Its high wear resistance and long life (up to 10 to 18 months) significantly reduce refractory materials’ consumption and maintenance costs and increase the furnace’s overall life and output value. Non-ferrous metal smelting: In the process of non-ferrous metal smelting, chrome corundum bricks are used as linings for copper smelting furnaces, zinc smelting electric furnaces, and other equipment due to their superior wear resistance and corrosion resistance, effectively resisting high-temperature melts and corrosion—the erosion of sexual atmosphere. 2. Petrochemical industry Chrome corundum bricks also have important applications in gasifi ers in the petrochemical industry. These gasification furnaces have been exposed to high temperatures (1350~1450℃), high pressures (3.1~8.53MPa),...
