Chromite Sand Chrome Ore Supplier Foundry chromite sand for foundry use as a highly fireproof sharpener for moulds and cores. Originally from South Africa. The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size. Physical composition Bulk Density 2.5-3g/cm3 Specific Gravity 4.0-4.8g/cm3 PH Value 7-9 The amount of the acid 2ML max Percent soil 0.1%max The sintered 1600 Filling Density 2.6g/cm3 melting temperature 2180°C
1. with excellent chilling characteristics, this characteristic does not reduce the thermal cracking, but can affect the temperature gradient, promote directional solidification without the use of cold iron. 2. Chromite is inert and does not react with other metal oxides. It is not wetted by manganese steel water. Chromite can be successfully used in manganese steel castings. 3. Linear expansion is small, and linear expansion is a factor that may cause sand inclusion in castings, so it may be used to mix wet sand mold for large castings.
