Import Graphite Petroleum Coke — Buy in Bulk from Supplier in Germany

WTZ Gmbh supplies graphite petroleum coke that results from graphitising green petroleum coke in an Acheson furnace at temperatures between 2500 °C and 3600 °C. The product achieves a fixed carbon content of at least 99 % and a nitrogen impurity below 300 ppm, as specified by the supplier. Sulphur is limited to a maximum of 0.03 % and ash does not exceed 0.5 %, meeting the stringent requirements of high‑purity carbon materials. The coke is offered in various size fractions, including 0‑0.5 mm and 1‑5 mm particles.

Typical grades of semi‑graphite petroleum coke exhibit a bulk density of 0.9‑1.0 g cm‑3 and a calorific value around 30 MJ kg‑1, values that align with the supplier’s description of an economical recarburiser. The lower sulphur and ash contents improve furnace efficiency and reduce slag formation during steelmaking. Standard moisture content for this class is below 0.5 %, and volatile matter is generally limited to 0.5 %, which matches the limits quoted in the listing. The material’s graphitisation degree places it between fully graphitised coke and raw petroleum coke, offering a balance of conductivity and reactivity.

Primary users include steel mills and foundries that require a consistent carbon source for recarburisation. The supplier notes that the product can be shipped under FOB or CIF terms and that MOQ is flexible, though exact quantities are not disclosed. Buyers should request the relevant ISO or SGS certificates to confirm compliance with international quality standards.

WTZ Gmbh is a German‑based supplier that appears in the imported tier of the marketplace. The company holds a harbour‑level trust tier, indicating a basic verification of its business registration. Its response rate is recorded as zero percent and no average response time is available, suggesting limited engagement through the platform.

The firm offers graphite petroleum coke intended for recarburisation in steelmaking and foundry processes. Apart from the product description, the source does not provide additional corporate details such as year of establishment, production capacity or client list. Prospective importers should therefore obtain direct confirmation of manufacturing facilities and any quality management systems in place.
