Bauxite Materials from Kerui

Importance of Calcined Bauxite in Refractory Industry

In the refractory industry, calcined bauxite plays a crucial role as a refractory aggregate. Its high alumina content, combined with excellent thermal stability and mechanical strength, makes it an ideal choice for manufacturing refractory bricks, refractory castable, and other refractory products. The use of calcined bauxite enhances the overall performance and longevity of refractory linings in high-temperature environments.

Importance of Buying Calcined Bauxite from China

Although there are abundant bauxite resources in the world, the countries that produce bauxite for refractory materials are China and Guyana. More importantly, due to the large-scale production of bauxite in China, the supply in the market is relatively abundant, which may lead to relatively low bauxite prices in China. Chinese manufacturers of calcined bauxite adhere to strict quality standards, ensuring that the product meets the required specifications. Many Chinese suppliers have established quality control systems and certifications, guaranteeing the consistency and reliability of the alumina refractory they offer.

Importance of Buying Calcined Bauxite from Kerui Refractory

Located in Xinmi City, Henan Province, China, Kerui factory has the reputation as “the hometown of refractory materials”. This factory is surrounded by rich mineral resources, including bauxite. In addition to the advantages of raw materials, Kerui is also constantly studying technology in order to provide customers with higher-quality refractory products. Kerui has exported calcined bauxite to more than 30 countries around the world, helping many customers to carry out projects smoothly. If you are looking for suitable calcined bauxite for sale, why not consider buying from Kerui?

Application in Precision Casting Industry
Customers can process the aluminium bauxite clinker into fine powder and make it into casting molds. Calcined bauxite molds can withstand liquid metal pouring at high temperatures while maintaining a stable size and shape, ensuring accuracy and surface quality of precision castings. If you’re like to get more details, please follow Kerui VK account.

Customers in Aluminum Industry

The main component of bauxite is alumina, and customers can purchase large quantities of bauxite to smelt aluminum oxide. The final products are used in a wide range of applications, such as defense, aviation, automobiles, electrical appliances, chemicals and daily life, etc.

Customers in Other Industries

Metallurgical Industry
Bauxite can be combined with various other materials to generate more applications. For example, after adding magnesia, bauxite and an appropriate amount of binder, the aluminum silicate refractory fiber is made, which can be used to cast the overall lining of the steel drum.

Factors to Consider When Choosing Calcined Bauxite

We can say that bauxite refractory is the base of your projects. Therefore, it’s important to choose suitable calcine bauxite for sale. When selecting calcined bauxite for your specific application, several factors should be considered:

Alumina Content of Calcined Bauxite

The alumina content of bauxite is a critical factor in determining its suitability for different applications. Higher alumina content generally indicates better heat resistance and mechanical strength. Therefore, it is important to select a calcined bauxite grade with the appropriate alumina content that aligns with your project’s requirements. The Al2O3 content of Kerui calcine bauxite is more than 70%, which performs good properties in making fire bricks.

Thermal Stability of Calcined Bauxite

Calcined bauxite should exhibit excellent thermal stability to withstand the extreme temperatures experienced in various applications. Consider the operating temperature range and thermal cycling conditions of your project and choose high alumina refractory with the required thermal stability to ensure optimal performance and durability. Anyway, most uses of bauxite powder in the refractory industry. Good thermal stability of alumina refractory products assures the safe production of high-temperature kilns.

Mechanical Strength of Calcined Bauxite

The mechanical strength of bauxite product influences its resistance to physical stress and structural integrity. Depending on the application, it is essential to select a grade of calcined bauxite that offers adequate mechanical strength to withstand the operational demands of the project. Through changing the ratios and compositions, Kerui offers high alumina refractory with strong mechanical strength. When you add this product into high alumina refractories or other places, it also brings excellent hardness.

Supplier Reputation of Calcined Bauxite

The reputation of suppliers is accumulated by product quality, service, customers feedback and many other aspects. If you find a calcined alumina manufacturer like Kerui Refractory, who owns good reputation in this industry, it’s a wise choice. You’ll find there also comes with stable product quality and professional service.
