Chromite Sand Separation Plant by SOGEMI | foundry-planet .

The chromite is used as facing sand due to its high conductivity of heat that avoids the sintering of the sand in contact with the molten metal and so permit to reach a good surface of the castings. Starting from a mixture in granular size of silica sand and chromite sand, Sogemi plant is able to separate completely the chromite.

Chromite Emerges as a New-Age Molding Material | Foundry .

Dec 4, 2011 . But, as HAI's foundry sands product manager Mitch Patterson explained, chromite sand is a high-refractory product, with a higher melting point than silica sand that makes it especially suited to high-temperature steel casting. In that way, SpheriChrome offers an effective, more affordable alternative to zircon.

Chromite - an overview | ScienceDirect Topics

The chromite glaze problem has been assumed to be the formation of fayalite (ferrous orthosilicate Fe2SiO4 with a melting point of 1205°C) as the reaction product between silica and chromite. Fayalite is not magnetic and so cannot be separated from the sand magnetically. During the re-cycling of the sand, this low melting.
