Refractory Coatings

Refractory coatings are essential materials used in the metal casting process to create a barrier between the molten metal and the mold or core surfaces. These coatings serve several important purposes, including:

  • Improving Surface Finish: Refractory coatings create a smooth and uniform surface finish on molds and cores, enhancing the quality and appearance of the final casted product.
  • Minimizing Defects: Coatings help prevent defects like veining, metal penetration, and scabbing by reducing the interaction between the metal and mold surfaces.
  • Heat Resistance: Refractory coatings provide thermal protection to the mold and core, allowing them to withstand the high temperatures of molten metal without deforming or breaking.
  • Reduction of Metal-Mold Reaction: Coatings act as a barrier, minimizing reactions between the molten metal and the mold material, which can lead to surface defects and impurities in the final casting.
  • Ease of Release: They facilitate the easy release of the solidified metal from the mold, preventing the casting from getting stuck or damaged during demolding.
