| Foundry sand |
| In the modern sand casting process, special sands are used to improve the casting quality and reduce the risk of defects. Due to the low thermal expansion and high | |
| refractoriness , Kerphalite KF is the ideal solution for Iron and Steel casting free of veining and finning.This special sand shows a real compatibility with silica sand, bulk density of 1,7 g/cm3 and does not contain any significant amount of crytalline silica. The consistancy of the Particle Size Distribution is the result of a state-of -the-art sieving and milling process located in our Glomel plant. Kerphalite KF is available in the following AFS grades: 50, 60, 70, 100. | |
