Calcium aluminate is an important additive in steelmaking, enabling efficient melting and improved steel refining by lowering the melting point and creating a more fluid slag. Produced from a combination of lime and alumina, it is precisely formulated to enhance impurity absorption. Its high thermal resistance and chemical stability make it a reliable choice under the harsh conditions of the furnace.
With controlled reactivity, calcium aluminate reduces heat losses and improves the final quality of the steel. Its use in steel melting and refining units boosts production efficiency while optimizing energy consumption, making it a trusted material for modern metallurgical processes.
Calcium aluminate is a key material in steelmaking, facilitating impurity removal by forming a fluid slag. Produced from lime and alumina derived from bauxite, it lowers the melting point, making the melting process faster and more economical. Its high thermal resistance and chemical stability ensure consistent performance under the extreme temperatures of furnaces. Beyond improving steel quality, the use of calcium aluminate reduces energy consumption and enhances the efficiency of smelting and refining operations in industrial units.
Calcium aluminate is one of the most widely used materials in the steel industry, playing a vital role in refining processes and facilitating melting. It is produced by combining lime and alumina derived from bauxite, along with carefully controlled amounts of other additives. After initial preparation, the mixture is either heated in melting furnaces to form complexes and lower the melting point, or sintered in kilns at temperatures up to around 1200 °C to achieve the desired properties.
The development and production of calcium aluminate were pioneered decades ago by leading companies, including Lafarge in France, and have since undergone significant advancements. Thanks to its high quality and its ability to create a more fluid and efficient melt, calcium aluminate has become an essential auxiliary material in modern steelmaking, especially during secondary melting and refining stages.
Calcium aluminate, with its low melting point and ability to form a fluid slag, not only facilitates the melting process but also enhances impurity absorption in steel. These properties make it a vital component in steelmaking operations, especially in electric arc furnaces and secondary refining units. Its high thermal resistance and controlled reactivity improve process efficiency and stability while optimizing energy consumption.
