Foundry Chromite sand is a natural process product 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.
Application:
(1)Chrome ore in casting production is mainly used for large steel surface sand, prevent casting surface adhering sand;
(2)Secondly the grinding powder for the refractory aggregate of foundry coating, chrome ore is chilling material, when modelling (core) alternative part cold iron.
