What’s the Application of Chromite Flour？
1. Refractory Applications
-
Foundry & Steelmaking: Chromite flour is used as a refractory material in high-temperature environments, such as linings for furnaces, ladles, and kilns, due to its high melting point (~2,180°C) and resistance to thermal shock.
-
Magnesia-Chrome Bricks: It is mixed with magnesia to produce refractory bricks used in cement rotary kilns and non-ferrous metal smelting.
2. Foundry Sand Additive
-
Used in green sand molds and cores to improve heat resistance and prevent burn-on defects in metal casting (especially for steel and iron).
3. Chemical Industry
-
Chromium Compounds: A precursor for producing sodium dichromate, chromium metal, and other chromium-based chemicals.
4. Welding Electrode Coatings
-
Added to welding rods to enhance arc stability and improve slag formation.
5. Pigments & Coatings
-
Some specialty pigments (e.g., chromium oxide green) are derived from processed chromite.
6. Geopolymers & Cement
-
Investigated as a component in alkali-activated binders for sustainable construction materials.
7. Abrasive & Polishing Compounds
-
Occasionally used in fine abrasive blends for precision polishing.
