Brown corundum is widely used in refractory materials in the foundry industry, mainly in the production of iron hook castables, anhydrous blister mud, corundum bricks, prefabricated parts, breathable bricks, ladle bricks, magnesium aluminum carbon bricks and other refractory materials.
The application of brown corundum in these refractory materials is mainly due to its unique physical and chemical properties, including high refractoriness, wear resistance, erosion resistance, corrosion resistance, high bulk density, and high alumina content.
These characteristics make brown corundum an important raw material for high aluminum and alumina refractories.
Refractory materials made of brown corundum not only have high load softening temperature and high temperature volume stability, but also will not deform at high temperatures, maintaining good thermal conductivity and oxidation resistance.
The application of brown corundum in refractory materials in the foundry industry also includes its use as aggregate and fine powder.
These characteristics enable brown corundum to effectively improve the durability and stability of the mold during the casting process, reduce mold loss, and thus improve production efficiency and product quality. In addition, the impurity content of brown corundum has an important influence on its performance and service life.
Therefore, taking appropriate measures to remove impurities during the smelting process, such as using secondary refining and smelting technology, can effectively solve the phenomenon of brown corundum powder explosion when using refractory materials and ensure the stability and quality of the product.
In summary, brown corundum is widely used in refractory materials in the foundry industry due to its unique physical and chemical properties. It not only improves the efficiency of the casting process and product quality, but also provides important technical support for the development of the foundry industry.
