Anode Carbon Block

https://www.tiantiancarbon.com/products/anode- , carbon-block.html

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
