5. Core Product Advantages

High Melt Efficiency with High Carbon & Low Ash

Our foundry coke features 86%–90% fixed carbon content and ash content as low as 8% max. It effectively raises cupola temperature, reduces coke consumption per ton of molten metal and lowers slag generation, bringing tangible cost benefits for casting production.

Stable & Clean Casting Quality

Strictly controlled sulfur (≤0.5%) and low volatile matter (≤1.5%) avoid excessive sulfur absorption in molten iron and unstable combustion. It ensures stable carbon absorption rate, reduces casting defects, and perfectly meets the precision requirements of ductile iron and high-grade gray iron production.

Graded Size for Diverse Working Conditions

Available in multiple particle sizes including 60–90mm, 90–150mm and 150–300mm. Each specification is precisely screened with uniform porosity and mechanical strength. Small sizes fit small cupola equipment, while medium and large sizes ensure excellent furnace permeability for large blast furnaces, avoiding material bridging and channeling, and maintaining stable furnace operation.

6. Quality Assurance & Inspection

We adopt ISO 9001 certified production management with full batch traceability. Each shipment is equipped with official Mill Test Certificate (MTC). Third-party inspection by SGS, Bureau Veritas or CCIC is acceptable on request.

All batches have traceable lot numbers, covering raw material sourcing, coking temperature records and final component test reports.

7. Lead Time & Logistics Service

• Standard Lead Time: 15 days after order confirmation

• Packaging: Bulk shipment, 1-ton jumbo bags or customized packaging

• Trade Terms: FOB / CIF available

• Trial Order Support: Accept small trial orders with 1×20FT container to start long-term cooperation
