Chromite is an Iron chromium oxide that occurs naturally in the earth's crust. This industrially essential mineral is used to produce metallic chromium, that is further used to produce Stainless and Tool Steel. The high heat stability property of this material makes it an essential refractory material. The chromium can be extracted from chromite. This is majorly utilized in super alloys production, chrome plating, as a pigment for products, like paint and glass, and as an oxidizing agent for tanning leather. India is amongst the top Chrome ore producing countries.
Naturally occurring spinel called Chromite Sand encompasses iron and chrome oxides. Chromite Sand can be identified by dark grey color and granular form. Possessing certain properties, it is used as core and mould making sand in grey iron and steel foundries. It has good chilling properties due to its high thermal conductivity. The dimensional stability can be assured due to low thermal expansion. Chromite Sand finds its major use in steel production as a well filler that protects sliding gates in steel holding ladles. As a fine flour, it is also used in manufacturing green glass beverage containers.

FAQs of Chromite Sand:
Q: How is Chromite Sand typically used in foundry applications?
A: Chromite Sand is primarily utilized as a mould and core sand in foundry processes due to its high refractoriness, low thermal expansion, and superior heat transfer properties. It helps produce smooth surface finishes and reduces casting defects in both ferrous and non-ferrous metal casting.
Q: What are the main benefits of using Chromite Sand with a grain size of AFS 45-55?
A: The specified grain size delivers optimal permeability and compaction, allowing even metal flow, precise casting, and minimal gas generation. This enhances both the structural integrity and the surface quality of metal castings.
Q: When should users choose Chromite Sand over other refractory materials?
A: Chromite Sand is an excellent choice for applications requiring resistance to high temperatures up to 1800C and strong chemical stability. It is ideal when dimensional precision and thermal shock resistance are critical, such as in intricate castings or where silica sand isnt suitable due to chemical reactivity.
Q: Where can Chromite Sand be sourced in India?
A: Chromite Sand is available through leading importers, suppliers, and traders located throughout India. It is typically offered in bagged packaging for convenient storage and transportation to industrial sites.
Q: What is the process for using Chromite Sand in glass production?
A: In glass manufacturing, Chromite Sand is incorporated as a raw refractory material lining furnaces and kilns. Its high melting point and stability help protect equipment from thermal wear and reduce the risk of contamination in glass products.
Q: How does the high Cr2O3 content benefit refractory applications?
A: A high Cr2O3 concentration increases resistance to slags and corrosive agents, extends service life in harsh environments, and contributes to better thermal performance in refractory linings.
