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
