South Africa chromite sand casting South Africa chromite sand casting , Originally from South Africa ,is a special kind of sand for casting , chromite sand casting is a natural spinel mainly composed of chromite , Chromite sand casting used as a highly fireproof sharpener for moulds and cores. Purpose 1 foundry industry Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. 2 steel industry In steel production, Chromite Sand Casting is used as well filler for protection of the sliding gate in large steel holding ladles. 3 glass industry When ground to a fine flour, Chromite Sand casting is used for the production of green glass beverage containers
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.
Foundry chromite sand is a natural process products of chromite through the broken screen classification, chrome ore, its main chemical composition of cr2o3, this kind of sand heated volume stability, high thermal conductivity, when in contact information with the molten metal, not only has good resistance to basic slag, not with ferric oxide and other chemical reactions, and itself has the characteristics of the solid phase sintering, can be a very good prevent the infiltration of molten metal, avoid to touch sand defects, suitable for all kinds of stainless steel, alloy steel and carbon steel gradually shape the original sand core and coating.
