Application of Coal-Based Foundry Coke

Coal-based foundry coke is a vital fuel and reducing agent in the casting and metallurgical industries, widely used in cupolas, hot metal smelting, and metal casting production. Its key features include high fixed carbon, low ash, strong mechanical strength, and stable combustion, which provide continuous heat and a reducing atmosphere at high temperatures. This ensures stable hot metal temperatures, improves melting efficiency, and enhances casting quality.

In practice, foundry coke not only supplies sufficient energy but also reduces the entry of harmful elements such as sulfur and phosphorus. This minimizes casting defects such as porosity and slag inclusion, resulting in castings with better mechanical properties and smoother surfaces. To meet different furnace types and process requirements, foundry coke is available in various sizes such as 80–120mm, 60–90mm, and 25–90mm, offering customers flexibility in use.

Thanks to its stable performance, competitive cost, and reliable supply, coal-based foundry coke is widely exported to steel plants and foundries, serving as a key raw material for efficient, safe, and high-quality production. With the continuous development of the global casting industry, the demand for high-quality foundry coke is expected to keep rising.
