Chromite sand AFS45-55 AFS50-55 Resin coated sand Advantages

Chromium ore sand is widely used in no-bake sand casting technology and sand casting, with particle sizes mostly being AFS40-45 (40-70 #), AFS35-40 (20-70 #), etc. For the RCS (resin-coated sand) casting process, finer grains such as Chromite sand AFS45-50/AFS50-55 (50-100 #) or AFS55-60 (70-140 #) are more commonly used as raw sand.

The moisture of dry Chromite sand

Dry Chromite sand is usually used for large, heavy, and structurally complex casting surface dry sand. Dry sand in casting needs to have high sand mold strength, fire resistance temperature, and resistance to molten steel erosion. Besides the sintering temperature and thermal conductivity, the moisture of chromite sand is an important technical index as well.

What is chromite sand used for?

46% Chromite sand is composed of chromium, iron, and oxygen (chemical formula FeCr2O4). It is an oxide mineral belonging to the spinel group. 46% content referring to Cr2O3 content more than 46%. The 46% chromite is mainly from the western ore belt centered around Rustenburg in South Africa and the eastern ore belt centered around STEELPORT and BUGERSFORT. Chromium ore sand has the characteristics of high sintering temperature, high thermal conductivity, and high specific gravity.
