Refractory 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
SICHENG focus is on supplying refractory grades chromite of South African origin with the following characteristics:
– Cr2O3 min. 46 % (typ. 48 %) / SiO2 max. 1.2 % (typ. 0.9 %)
– high refractoriness
– high thermal conductivity
– coarse sizing, varying from AFS 30 to AFS 45 (top grain size up to 1.5 mm).
Refractory grades can be shipped loose in bulk or packed in big bags, in both FCL’s and bulk carrier loads, depending on customer’s requirements.
