Coke ovens are industrial furnaces used to convert coal into coke, a porous and carbon-rich material. This process, known as carbonization, involves heating coal in the absence of air at high temperatures, typically around 1,000 degrees Celsius. The resulting coke is primarily used in the production of steel and acts as a fuel and reducing agent in blast furnaces. The coke-making process also produces by-products, such as coal tar and ammoniacal liquor, which can be further processed for various applications. Coke ovens are essential in the metallurgical industry, providing the necessary materials for steel manufacturing and other industrial processes.
