Semi Coke for Ferroalloy Production
A procurement guide for matching semi coke chemistry, size and furnace behavior to ferroalloy burden requirements.
Application guide
This page is a technical discussion guide, not a claim of existing customer supply, process approval or guaranteed performance. Final suitability must be confirmed by the buyer against its process, standard and trial.
Application guide
Application objective
Define the alloy, furnace route and burden design before reviewing carbon chemistry, reactivity and particle size.
Process-fit discussion
- 01
Identify the target ferroalloy and furnace technology.
- 02
Confirm fixed carbon, ash, sulfur, phosphorus, moisture and any ash-chemistry limits.
- 03
Define size distribution, fines tolerance, reactivity, resistivity or trial requirements.
