As can be seen, the chromite sand grains have irregular shapes and many visible angular edges. Table 2 summarises the chemical composition of the chromite sand that was used in the study based on 20 measurements that were made on the grain surface. Table 2. Elemental wt.% contents of chromite sand CS in the analysed area (in Figure 3b).
Foundry grade Chromite grains are a kind of foundry sand with high refractoriness. The content of chromium oxide of casting chromite sand should be at least 46%. That will get high Solid-phase sintering temperature. Chrome ore sand is especially featured with its high thermal conductivity. It can not only make the casting steel cool quickly, but also prevent casting iron& steel from sand …
