Chromite sand Euskatfund

Chromite Sand is a special sand with very good properties at high temperatures. Provides a high resistance to penetration of the liquid metal, and compared with other sands produce more rapid cooling of the casting. Thermal expansion is much lower than the silica sand thus reducing the problems resulting from the expansion of the sand.

Why Chromite Sand Minerals Technologies Inc.

Silica Sand undergoes an alpha-beta phase transformation at approx 350oC 650oC. This corresponds to the temperature zone that the mould experiences during cooling. This can lead to expansion defects such as veining or cracking in castings where silica sand moulds are used Chromite has a much lower expansion over the same temperature range.

Refractory chromite sand SICHENG Chromite Sand

2021-9-15  Refractory chromite sand is mainly used in chrome-magnesia or magnesia-chrome bricks. 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
