Casting Graphite Powder USES: casting industry, the Graphite coated on the surface of the solid, can form a smooth film adhesion strong, this is the appearance of graphite good coating performance, it is a good casting remover casting commonly used graphite powder have crystalline graphite powder (Flake Graphite powder) or aphanitic graphite powder (earthy graphite powder, also known as microcrystalline toner, black lead powder). So far there are a lot of manual production of thin wall small villages and towns small factory without pulverized coal in the sand, but with a soft brush brush earthy graphite powder to the surface of green sand mold, pouring out of the casting surface is quite smooth. Although when pouring molten iron graphite powder does not form the light carbon, but the graphite iron liquid wetting Angle is greater than 90 °, the sand mould is not iron liquid wetting. And the surface of the pore is blocked by the soil and stone ink, the iron liquid is not easily penetrated and drilled into the sand, which can prevent the casting sand and improve the surface of the casting surface. The graphite powder has a good lubrication effect, so that the compactness of the sand is improved, the air permeability is decreased, the resistance of the sample is reduced, and the molding properties of the sand are improved.
