What is the main specifications and advantage of our high strength foundry coke and casting coke

Foundry Coke

Foundry coke is a core raw material for iron casting and cupola furnaces. It features high fixed carbon, low sulfur and low ash, with stable combustion performance to optimize casting quality and production efficiency.

Application
Iron casting, cupola furnace operation, metal smelting and foundry industry

High-Carbon Low-Ash Formula for Superior Melt Efficiency: Our foundry coke delivers a minimum 86%- 90% fixed carbon content with ash capped at just 8%, directly translating to higher cupola temperatures, reduced coke consumption per ton of molten metal, and significantly less slag formation -- every percentage point of carbon gain is measurable profit for your casting operation.

Tight Sulfur & Volatile Control for Cleaner Metal Output: With sulfur strictly controlled to ≤0.5% and volatile matter ≤1.5%, this coke minimizes sulfur pickup in your iron and eliminates combustion instability. The result is consistent carbon pickup rates and fewer casting defects, particularly critical for ductile iron and high-grade gray iron foundries demanding metallurgical precision.

Three-Tier Size Grading for Application-Specific Performance: Available in 60-90mm, 90-150mm, and 150-300mm fractions, each size band is screened for uniform porosity and mechanical strength. Smaller grades suit compact cupola setups; mid and large sizes deliver optimal bed permeability in larger blast furnaces --no bridging, no channeling, just stable burden descent.

ISO-Certified Production with Batch-Level Traceability: Every shipment is backed by ISO 9001-certified manufacturing protocols and a full mill test certificate (MTC). Third-party inspection by SGS/BV/CCIC is available on request for every order. Each batch carries traceable lot numbers tied to raw coal sourcing, coking temperature logs, and final composition reports.

15--Day Standard Lead Time with Flexible Logistics: Orders ship within 15 days of confirmation. We offer bulk vessel loading, 1-ton jumbo bags, or custom packaging by client specification. Our team coordinates FOB/CIF shipments from major Chinese ports, and we support trial orders starting at one 20ft container --because every long-term partnership starts with a well-executed first delivery.
