1. The Technical Indicator Requirements For Needle Coke Used In Graphite Electrodes Are Mainly Based On Two National Standards: coal-based needle coke (GB/T 32158-2025) And Petroleum-based Needle Coke (GB/T 37308-2019). Below Is A Detailed Summary Of The Core Indicators.
I. Coal-based Needle Coke (GB/T 32158-2025)
This Standard Applies To Needle Coke Produced Using Coal Tar Pitch As Raw Material Through Raw Material Pretreatment, Delayed Coking, And High-temperature Calcination. The Core Indicators Are As Follows:
Indicator Requirement Remarks
True Density =2.13 G/cm³ Reflects The Structural Compactness Of The Coke
Ash Content =0.1% (mass Fraction) Affects Electrode Purity And Electrical Conductivity
Sulfur Content =0.5% (mass Fraction) Reduces Oxidation Burn-off Of Electrodes
Volatile Matter =0.5% (mass Fraction) Reduces Volume Shrinkage During The Baking Process
Coefficient Of Thermal Expansion (CTE) =1.3×10?6/°C (25–100°C) Key Indicator Determining High-temperature Stability Of Electrodes
II. Petroleum-based Needle Coke (GB/T 37308-2019)
This Standard Applies To Petroleum-based Needle Coke Produced Using Petroleum Residue, Catalytic Cracking Slurry Oil, And Similar Materials As Raw Materials. It Is Classified By Quality Grade, With The Following Core Indicators:
Indicator First Grade (YZA) Qualified Grade (YZB) Remarks
True Density =2.13 G/cm³ =2.05 G/cm³ First Grade Requires Higher Compactness
Ash Content =0.3% (mass Fraction) =0.5% (mass Fraction) First Grade Has Higher Purity
Sulfur Content =0.5% (mass Fraction) =1.0% (mass Fraction) First Grade Has Less Sulfur Contamination
Volatile Matter =0.5% (mass Fraction) =1.0% (mass Fraction) First Grade Has More Stable Processing Performance
Coefficient of thermal expansion (CTE) =1.3×10?6/°C (25–100°C) =2.0×10?6/°C (25–100°C) First Grade Has Better High-temperature Stability
