High Efficiency Coal Dust for Foundry Applications

As a high-performance clay sand casting material, High-Efficiency Foundry Coal Powder occupies an irreplaceable position in cast iron production with its excellent process adaptability and quality stability, and is a cast iron auxiliary material with excellent cost performance. Through scientific proportioning and precise processing, this product ensures high fixed carbon content, low impurity content and uniform and moderate particle size. It forms a continuous and uniform bright carbon isolation layer during high-temperature pouring, effectively preventing casting defects such as sand burn, sand inclusion and surface roughness, greatly improving casting appearance quality and internal performance. As a core clay sand casting material, this product can optimize molding sand air permeability, fluidity, wet compressive strength and thermal stability, reduce molding sand moisture, decrease problems such as blowholes, sand wash and sand swelling, suitable for high-speed automatic molding…
