High Performance Foundry Coal Dust Solution

In modern clay sand casting production, High-Efficiency Foundry Coal Powder has become an essential clay sand casting material with stable and reliable performance and economic and efficient advantages, and is also a basic cast iron auxiliary material to guarantee cast iron quality. Through deep processing and strict quality control, this product has high fixed carbon content, moderate volatile matter and extremely low sulfur and ash content. It can quickly form a uniform and dense bright carbon film under high-temperature iron liquid, effectively isolating molten metal and sand molds, preventing defects such as sand burn, sand inclusion and peeling, significantly improving casting surface quality and yield. As a core clay sand casting material, this product can optimize molding sand physical and process properties, reduce moisture content, improve air permeability, enhance fluidity and thermal stability, making sand molds suitable for high-speed automatic molding lines, reducing moldi…
