REFRACTORY GRADE
Chromite Sand Refractory Grade mainly used in chrome-magnesia, casting sands in cores and moulds in steel, iron foundries and base material in sliding gate mixes or plugging sands in ladles at steelworks.
Refractory Grade Chrome ore is able to overcome the typical disadvantages of magnesia (shrinking tendency and high temperature coefficient). The high chromium content of typical 48% Cr2O3 and low silica of typical 0,9% SiO2, coarse sizing and high Cr:Fe ratio of close to 2:1 makes our refractory grade being appreciated world-wide.
