High Carbon GPC 0-5mm For Foundry Casting

High carbon GPC, also called graphitized petroleum coke, is a carbon additive made from petroleum coke through high-temperature graphitization. After graphitization, the material has high fixed carbon, low ash, low sulfur and low volatile matter, which makes it suitable for foundry casting and molten iron carbon adjustment.

The 0-5mm particle size is designed for foundry use where feeding flexibility and absorption speed are important. Compared with larger lumps, 0-5mm GPC can contact molten metal more easily and support faster carbon dissolution. Compared with very fine powder, controlled granular material helps reduce excessive dust and material loss during weighing, storage and feeding.

For foundry casting, carbon adjustment is not only about adding carbon content. The recarburizer also needs to support cleaner melt control, stable absorption and lower impurity input. High carbon GPC 0-5mm can be used when your casting process needs a reliable carbon source for gray iron, ductile iron or other foundry production.

Foundry Casting Recarburizing

High carbon GPC 0-5mm is suitable for foundry casting when your production needs to adjust carbon content in molten iron. The high fixed carbon level helps provide effective carbon input, while low ash and low volatile matter support cleaner use during melting.

Molten Iron Carbon Adjustment

You can use GPC 0-5mm when your casting process needs stable carbon recovery. The controlled particle size helps the material spread and dissolve more evenly, which supports better carbon adjustment during foundry production.

Gray Iron and Ductile Iron Production

High carbon GPC can be used in gray iron and ductile iron casting when your process requires a cleaner recarburizer with controlled sulfur and ash. Before order, we can help you confirm whether 0-5mm, 1-3mm or another particle size is more suitable for your feeding method.

Q: What is High Carbon GPC 0–5mm used for?
A: High Carbon GPC 0–5mm is used as a recarburizer for foundry casting and molten iron carbon adjustment. You can use it when your casting process needs high fixed carbon, low sulfur, low ash and stable carbon absorption.

Q: Why choose 0–5mm GPC for foundry casting?
A: The 0–5mm particle size is practical for foundry feeding and carbon absorption. It is easier to dissolve than large lumps and easier to handle than excessive fine powder, helping reduce dust loss and uneven addition.

Q: What specification should I check before buying foundry GPC?
A: You should check fixed carbon, sulfur, ash, volatile matter, moisture and particle size distribution. If your process has stricter requirements, nitrogen and fine powder ratio can also be confirmed by batch COA.

Q: How do you pack High Carbon GPC for export?
A: We usually pack High Carbon GPC in 1MT FIBC jumbo bags. Moisture-proof packing or customized export packing can be confirmed according to your storage, handling and shipment requirements.
