Brown corundum
is made from calcined bauxite in an electric arc furnace after recovery process. Coke and coal are two carbon sources commonly used as recovery agents. During the smelting process, excessive impurities (iron oxide, iron oxide, Silicon dioxide and titanium oxide) are restored to metal.
Due to the increasing demand for high-quality, highly abrasive abrasives and refractory materials, people are looking for brown corundum (BFA) with optimized hardness and usability. To achieve the function of brown corundum, it is necessary to Understand how the chemical composition and impurities can grow or degrade its quality.
Each bauxite origin has its own unique chemical composition and chemical nature. Therefore, brown corundum
producers can combine bauxite from different origins to obtain an optimized furnace charge, which can provide economic and applicable aspects. The advantages of brown corundum clearly describe these basic chemical and physical personalities. Because the production and consumption of brown corundum has regional personalities, producers and consumers are very familiar with each other. The specificity of the ultimate application of brown corundum Quality request.
The regional output of brown corundum has changed in the past two decades. Many brown corundum producers in North America and Europe have either stopped production or merged. At the same time, China has become the main supplier of brown corundum in the world. They also experienced similar mergers. In this process, the quality requirements of special products outside the general brown corundum technique conditions were probably ignored, and the change of suppliers probably caused some defects in product functions.
The technical conditions for the production of brown corundum in order to achieve high quality of the ultimate product require an understanding of the application direction of the product and the production process of brown corundum. The grinding and refractory characteristics of brown corundum are subject to its basic The chemical composition, the content of impurities, and the spread of impurities in its crystal structure spread.
