Briquetted coke, also known as coke briquettes or coke fines, is a processed form of metallurgical coke that has been compressed into briquettes. These briquettes are generally used as a supplemental fuel and carbon source in various industrial processes, such as steelmaking and foundry applications. The briquetting process involves compacting fine particles of metallurgical coke into a denser and more manageable form.
Here are some key points about briquetted coke:
1. Composition: The composition of briquetted coke includes metallurgical coke fines as the main carbonaceous material and a binder to hold the briquettes together. The binder, often derived from coal tar or pitch, helps maintain the structural integrity of the briquettes.
2. Applications: Briquetted coke is used as a supplementary carbon source in various industrial processes. It can be added to the charge materials in blast furnaces during iron and steel production. The briquettes contribute to the overall carbon content and serve as a source of energy in the reduction of iron ore.
3. Improved Handling and Storage: The briquetting process transforms loose coke fines into compact and uniform briquettes, making them easier to handle, transport, and store. This can be advantageous for industrial operations that require a more manageable form of coke.
4. Uniform Combustion Properties: Briquetted coke tends to have more uniform combustion properties compared to loose coke fines. This can contribute to improved process control and efficiency in industrial applications.
