聚兴产品结构
页面延续旧图册阅读逻辑，但按当前公开产品主线排序：石油焦供应、CPC、GPC、石墨电极、石墨碳素制品、质量服务与包装交付。
石油焦供应应按焦种、硫分、灰分、水分、挥发分、固定碳、颗粒形态、当前批次、包装和交付条件来确认。
| 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 是原石油焦经煅烧后的产品。煅烧过程降低水分和挥发分，提高密度、机械强度、导电性和抗氧化性能。
| 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 由石油焦经高温石墨化处理形成，公开沟通重点应放在固定碳、硫分、灰分、挥发分、水分、必要时的氮含量、粒度和用途。
| 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. |
石墨电极以石油焦、针状焦为主要原料，以煤沥青为结合剂，经煅烧、配料、混捏、压型、焙烧、浸渍、石墨化和机加工制成，主要用于电弧炉炼钢、冶炼硅、冶炼黄磷等场景。
| 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. |
旧图册覆盖石墨粉、石墨块、石墨圆饼、石墨棒、石墨瓦、石墨电极碎、石墨坩埚、石墨模具和石墨电极吊头。这类产品应按形态、材质路线、尺寸、图纸、数量和用途沟通。
| 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. |
煅烧针状焦是高品质碳材料原料，具有金属光泽、明显流纹结构和针状纹理，可用于超高功率电极、特种碳材料、碳纤维及复合材料等方向。
| 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. |
对于石油焦、CPC 和 GPC，质量服务与包装应围绕批次 COA、产品照片、包装照片、吨包、标签、防潮保护和装柜资料展开。
| 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. |
