Анодний вугільний блок

Anode carbon block is used in industrial aluminum electrolysis cells. It has two roles in it. One is as a conductive material; the other is to

participate in the electrochemical reaction of the anode.

During electrolysis, a direct current is passed through the electrolytic cell. Then the block converts electrical energy into chemical energy.

Because the electrochemical reaction is continuously consumed, the factory must replace it regularly to ensure regular production operation.

The general replacement cycle is 20-34 days. The current density of the product on the electrolytic cell is generally 0.70-0.90A/cm3.

З чого вона зроблена?

The main raw materials include petroleum coke and pitch coke, which are processed by calcination, medium crushing, screening, fine crushing, etc. to ensure the quality and uniformity of the raw materials.

Then, the processed raw materials are mixed with coal tar, which acts as a binder. This process includes melting the asphalt, mixing with the raw materials, kneading, and forming rectangular вуглець blocks with certain strength and density through molding processes such as extrusion or vibration molding.

Finally, the raw anode carbon blocks need to go through a roasting process, which aims to remove volatiles and coke the asphalt, thereby improving the mechanical strength and conductivity of the carbon blocks. The roasting temperature is usually between 1100 and 1200 degrees Celsius.

Заявка

Anode carbon block is mainly used in the production process of electrolytic aluminum. The anode is the positive electrode in the aluminum electrolytic cell and participates in the electrochemical reaction. When they are continuously consumed, aluminum liquid is generated at the cathode, which is an aluminum reduction process.

Ключові особливості

Чудова електропровідність

Engineered for optimal performance, they have high electrical conductivity. This feature enables efficient electron transfer, an essential trait for

driving various electrochemical processes.

Excellent Thermal Conductivity and Resistance

It is crafted to withstand extreme temperatures without compromising performance, thanks to its exceptional thermal conductivity and resistance.

With this, the block can manage generated heat efficiently, ensuring its durability and longevity.

High Chemical Stability

With a chemically stable nature, it doesn’t readily react with other chemicals. This property ensures that the block remains inert during

electrochemical reactions, preventing unwanted side reactions and yielding accurate, reliable results.
