Coke ovens are industrial furnaces used to convert coal into coke, a porous and carbon-rich material. This process involves heating coal in the absence of air, which drives off volatile substances and leaves behind solid carbon. Coke is primarily used in the production of iron and steel in blast furnaces, where it serves as both a fuel and a reducing agent. The operation of coke ovens is crucial in the metallurgical industry. The ovens are typically arranged in long rows, and the process can take several hours. The resulting coke is essential for high-temperature processes, making it a key component in the manufacturing of various metal products.
