About Foundry Coal Dust
Foundry coal dust, also called sea coal, is finely ground coal added to green moulding sand. It helps give cleaner casting surfaces and makes sand easier to remove from iron castings.
Uses and applications of foundry coal dust
- Green sand moulding: additive in grey and ductile iron foundries to reduce metal penetration and burn-on.
- Surface finish: helps produce a smoother casting skin and better shake-out.
- Sand systems: used along with bentonite in prepared sand mixes.
- Other uses: carbon source in some metallurgical and fuel blending applications.
Grades, forms and packing
Foundry coal dust is supplied as fine powder ground from selected coal. Fineness, volatile matter, ash, sulphur and moisture are shared with the quotation, with a COA on request, because the right values depend on your sand system and castings. Packing is in HDPE bags, with trial quantities for new foundries and regular lots for running plants. Other foundry materials are listed under Refractory & Foundry Minerals.

Storage and handling
Store in a dry, covered and well-ventilated area away from heat and flame. Fine coal dust can burn and, in a dust cloud, can ignite, so keep areas clean and avoid dust build-up. Wear a dust mask and goggles while handling, and follow the SDS.

Frequently asked questions about Foundry Coal Dust
Why is coal dust added to foundry sand?
During pouring, the coal releases gases and forms a carbon layer that reduces metal penetration into the sand, which gives a cleaner casting surface.
Is sea coal the same as foundry coal dust?
Yes. Sea coal is the common foundry name for finely ground coal used in green sand.
How much should be added?
The addition depends on your sand system, casting size and metal. Foundries usually set it by trial and sand testing.
Do you share test values?
Yes. Volatile matter, ash, moisture and fineness are shared with the quotation and a COA on request.
