Foundry Filler Sands Types Uses and Advantages African

Foundry Filler Sands Types Uses And Advantages African

Of all types of filler sands, Chromite-based sands are the most used. For the most part, the most important properties of a filler sand are particle-size distribution, low thermal expansion, flexibility, refractoriness, composition, and packing.These properties have a significant impact on the formation of the sintered crust and its properties when the filler sand makes contact with liquid steel.
