Hebei Tiantian Carbon Co., Ltd
Anode Carbon Block
Product Description
The anode carbon block also known as carbon anode block or electrolytic anode carbon is a crucial component in aluminum production, manufactured from premium petroleum coke and coal tar pitch. Our pre-baked anode blocks offer exceptional performance in harsh electrolytic environments with temperatures exceeding 950°C.
Our rectangular-shaped anode carbon blocks feature:
Precision-engineered surface grooves and protrusions for secure assembly
Through-groove designs for enhanced gas emission specific to model types
Dimensional stability within ±2mm tolerance after high-temperature calcination
The production of our carbon anode blocks follows strict industrial protocols:
1. Raw Material Preparation
We source ultra-low sulfur petroleum coke S content 1.5% and high-quality coal tar pitch QI content 6-12% to ensure product consistency.
2. Precise Formulation Mixing
Our proprietary mixing technology achieves:
Optimal binder content: 14.5-16.5%
Homogeneous paste temperature: 160±5°C
3. High-Pressure Forming
Using 3000-ton vibro-compaction presses, we achieve green density of 1.65-1.72 g/cm³.
4. Controlled Baking Process
Our 72-hour baking cycle features:
Precisely controlled heating rate: 15°C/hour
Maximum temperature holding at 1150°C for 48 hours
