General Products Manual
A bilingual searchable product manual covering petroleum coke supply, CPC, GPC, graphite electrodes, graphite carbon products, quality service and ton-bag delivery.
Product Structure
The manual keeps the old brochure reading logic, but uses the current public product priority: petroleum coke supply, CPC, GPC, graphite electrode, graphite carbon products, quality service and packaging delivery.
Petroleum coke supply should be reviewed by coke type, sulfur, ash, moisture, volatile matter, fixed carbon, particle form, current batch, packing and delivery conditions.
| Coke type / 焦种 | Confirm raw petroleum coke, calcined petroleum coke, graphitized petroleum coke or special coke route. |
|---|---|
| Batch fields / 批次字段 | Sulfur, ash, moisture, volatile matter, fixed carbon, particle size and photos. |
| Packing / 包装 | Ton bag, small bag inside jumbo bag, buyer label and moisture protection. |
CPC is produced from raw petroleum coke after calcination. Calcination removes moisture and volatile matter, improves density, mechanical strength, conductivity and oxidation resistance.
| Fixed carbon / 固定碳 | Typical inquiry values include 98.5% min or batch-confirmed values. |
|---|---|
| Sulfur / 硫分 | Discuss by low, medium or target maximum sulfur requirement. |
| Ash / volatile / moisture | Ash, volatile matter and moisture are key fields for batch review. |
GPC is produced by graphitizing petroleum coke at high temperature. Public communication should focus on fixed carbon, sulfur, ash, volatile matter, moisture, nitrogen when required, particle size and application.
| Fixed carbon / 固定碳 | Common RFQ values include 98%, 98.5% or batch-confirmed values. |
|---|---|
| Particle size / 粒度 | 0-2 mm, 1-5 mm, 5-8 mm, 8-25 mm and customized screening by order. |
| Properties / 特性 | Electrical and thermal conductivity, high purity, crystalline structure, stability and lubrication. |
Graphite electrodes are made from petroleum coke, needle coke and coal pitch through calcining, batching, kneading, forming, baking, impregnation, graphitization and machining. They are used as conductive materials in arc furnaces for steelmaking, silicon smelting and yellow phosphorus smelting.
| Grades / 等级 | RP / HP / UHP, with grade, diameter, length and nipple confirmed by order. |
|---|---|
| Size range / 尺寸范围 | Common diameter 75-700 mm; confirm grade, size and batch route by order. |
| Key indexes / 关键指标 | Electrical resistivity, bulk density, flexural strength, elastic modulus, ash, CTE and current load. |
The old manual covers graphite powder, graphite block, graphite round cake, graphite rod, graphite tile, graphite electrode scrap, graphite crucible, graphite mold and graphite electrode lifting plug. These products should be discussed by form, material route, size, drawing, quantity and application.
| Graphite powder / 石墨粉 | Fixed carbon, particle size, ash, moisture and use case. |
|---|---|
| Graphite block / 石墨块 | Extruded, molded or isostatic material; size, density, resistivity and machining requirement. |
| Graphite rod / 石墨棒 | Diameter, length, particle type, density and strength requirement. |
Calcined needle coke is a high-quality carbon raw material with metallic luster, obvious flow texture and needle-like particle structure. It is used for high-end carbon products such as UHP electrodes, specialty carbon materials and composite materials.
| Fixed carbon / 固定碳 | >99% as a reference field from the old manual. |
|---|---|
| Ash / 灰分 | ≤0.5% as a reference field from the old manual. |
| Volatile / 挥发分 | ≤0.5% as a reference field from the old manual. |
For petroleum coke, CPC and GPC, quality service and packing should focus on batch COA, product photos, packing photos, ton bags, labels, moisture protection and loading documents.
| COA / 检测资料 | Fixed carbon, sulfur, ash, moisture, volatile matter, nitrogen when required and particle size. |
|---|---|
| Batch proof / 批次证据 | Product photos, packing photos, labels, sample needs and loading photos when required. |
| Ton bag / 吨包 | Common bulk packing for petroleum coke, CPC and GPC granular materials. |
