Product Description
High Quality Foundry Coke | Cupola Furnace Fuel for Iron Casting & Metal Smelting | Factory Direct
Foundry coke is a specialized carbon material produced from high-quality coking coal through high-temperature carbonization in specially designed ovens . It is the primary fuel for melting iron in cupola furnaces, playing a critical role in the casting industry
Compared to blast furnace coke, foundry coke features larger lump size (80-120mm), lower reactivity, lower porosity, higher crushing strength, and lower ash and sulfur content . These characteristics ensure efficient melting, proper superheating of molten iron, and good permeability by supporting the charge column in cupola furnaces .
Our foundry coke is produced in China's premier coking coal regions (Shanxi), ensuring consistent quality and stable supply for foundries worldwide.

Major Industrial Applications
1. Iron Casting (Cupola Furnaces)
Primary application for melting iron in foundries. The coke is charged in two parts:
Bed coke: Bottom layer that supports the entire charge column and provides initial heat
Layer coke: Added alternately with metal layers to replenish consumed coke
2. Non-Ferrous Metal Smelting
Used in blast furnaces for smelting copper, lead, zinc, titanium, antimony, and mercury, acting as both heat source and reducing agent
3. Forging Industry
Serves as high-quality smokeless fuel in forging operations
4. Refractory Production
Fuel for firing limestone, dolomite, and gypsum in building materials production
5. Water Treatment
Used as a sorbent in water treatment plants to remove machine oil and other contaminants
6. Ferroalloy Production
Fuel and reducing agent in ferroalloy manufacturing
Our Factory Advantages: The Source of Quality
1. Premium Raw Material Source
Our production is based in Shanxi province, China's premier coking coal region, ensuring access to high-quality coal with optimal coking properties .
