Product Description

China Xingshi Caron- Graphite Electrode Introduction

Graphite electrodes are high-temperature conductive core components designed for industrial melting and refining processes. Made from premium petroleum coke, pitch coke, and needle coke as raw materials, with coal tar pitch as a binder, they undergo kneading, molding, dipping, roasting, graphitization (up to 2800-3000℃), and precision machining. As the key conductive medium in electric arc furnaces (EAFs), they convert electrical energy into intense arc heat (up to 3000℃) to melt and refine metals, ensuring efficient and stable industrial production.

Core Models in Worldmarketing:
           Diameter Range: 75mm - 700mm (customizable for special requirements)
           Length Range: 1500mm - 2700mm (with strict length tolerance control)
           Power Grades: RP (Regular Power), HP (High Power), UHP (Ultra High Power)

Applications

Xingshi Graphite Electrode Appliocation Area

1. Electric Arc Furnace (EAF) Steelmaking
    Graphite electrodes serve as the core conductive component in EAFs. They convert electrical energy into intense arc heat (up to 3000℃) to melt scrap steel, pig iron, and other raw materials, enabling large-scale steel production.

2. Ladle Furnace (LF) Refining
     In secondary steel refining, graphite electrodes provide high-temperature heat to adjust the composition and temperature of molten steel. This process enhances steel purity, reduces impurities, and improves mechanical properties (e.g., hardness, toughness).

3. Ferroalloy Smelting
    Graphite electrodes are used in submerged arc furnaces to smelt ferroalloys (e.g., ferrosilicon, ferromanganese). These alloys are critical additives for manufacturing high-performance steel (e.g., automotive, construction steel).

4. Industrial Silicon Smelting
      In electric arc furnaces, graphite electrodes heat quartz sand and carbon materials to produce industrial silicon— a key raw material for solar panels, semiconductors, and silicone products.   
 

Packaging & Shipping

Xingshi Graphite Electrode Packaging Details

Standard Packaging (FCL Shipment): Wooden fence Case are adopted for container loading. This packaging ensures stable placement during ocean transport, effectively preventing collision and damage to graphite electrodes while optimizing container space utilization.
Customized Packaging (LCL Shipment): For customers requiring enhanced protection for less-than-container-load (LCL) shipments, we offer wooden case packaging. The solid wooden structure provides full enclosed protection against external impacts during multi-party handling. Please note that this customized option will incur a higher cost due to increased material and labor inputs.
