High Efficiency Foundry Coal Dust

High-Efficiency Foundry Coal Powder is a classic and core clay sand casting material, as well as an indispensable cast iron auxiliary material in cast iron production. It plays a key role in improving casting surface quality and optimizing molding sand performance in green sand and clay sand systems. Selected from low-sulfur, low-ash, high-fixed carbon raw materials, this product forms high-quality powder suitable for casting process through multi-stage grinding and precise particle size control. It can work synergistically with foundry compound sand, foundry sodium bentonite and foundry starch to comprehensively improve sand mold high-temperature performance and pouring stability. As a professional clay sand casting material, this product forms a uniform bright carbon layer under high-temperature iron liquid, effectively blocking contact between molten metal and sand particles, preventing defects such as sand burn, sand inclusion and peeling, significantly improving casting surface fi…
