Product Description

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. Refractory products can be broadly divided into basic, neutral, and acidic groups, which relate to the type of refractory environment the product has been designed for (e.g., basic oxygen steelmaking) and the minerals used in its manufacture.
 
Minerals commonly used for refractories include (but are not limited to) alumina, bauxite, graphite, kaolin, magnesia, and zirconium. These minerals are produced globally but, in some cases, not always of grades suitable for refractory applications (e.g., magnesite and bauxite).
 
One of the most robust refractories is alumina, which consists of aluminum oxide and traces of other materials. Alumina is highly stable chemically and has superior hardness, strength, and spalling resistance. Refractory suppliers manufacture alumina that is suitable for lining furnaces operating at temperatures up to ***3 degrees Celsius.
 
The raw ores of alumina are mainly bauxite or flint clay, or mixed homogeneous materials.
 
Our calcined bauxite products have high alumina and low iron content, making them ideal refractory materials. We use our crushing and sizing technology to supply customers with the highest quality sized calcined bauxite and brown fused alumina. Quality is of the utmost importance, and we are constantly aware that any deviation from our high standards could have major implications for refractory lining stability.
