Prebaked anode is an important raw material for chemical production, which is widely used in aluminum electrolysis, calcium carbide production, ferroalloy smelting and other fields. It is made of petroleum coke, pitch coke and other carbon materials and coal tar and other binders through kneading, molding, roasting and other processes, with excellent properties and a wide range of uses.

First, the pre-baked anode has good electrical and thermal conductivity. This is because the main component of the pre-baked anode is carbon material, which has excellent electrical and thermal conductivity. In the process of aluminum electrolysis, the pre-baked anode, as the anode of the electrolytic cell, can transfer current and heat to ensure the smooth progress of the electrolysis process.

Secondly, the prebaked anode has high temperature stability and oxidation resistance. In the high-temperature electrolysis environment, the pre-baked anode can remain stable, not easy to deform and damage, and at the same time has anti-oxidation performance, can resist the erosion of oxygen. This enables the pre-baked anode to be used for a long time under harsh working conditions, and improves the production efficiency and stability of aluminum electrolysis.

In addition, prebaked anodes also have a lower resistivity and a higher mechanical strength. The lower resistivity makes the pre-baked anode less energy loss when passing current, and improves the electrolysis efficiency; the higher mechanical strength ensures that the pre-baked anode can withstand greater pressure and impact during use, and is not easy to damage.

In terms of use, pre-baked anodes are mainly used in the aluminum electrolysis industry. In the process of aluminum electrolysis, the pre-baked anode is used as the anode of the electrolytic cell, and the electrolyte is formed between the pre-baked anode and the cathode, and the aluminum oxide is decomposed into aluminum and oxygen by the action of the current. The quality and performance of pre-baked anodes have an important influence on the production efficiency and product quality of aluminum electrolysis.

In addition to the aluminum electrolysis industry, prebaked anodes are also widely used in calcium carbide production, ferroalloy smelting and other fields. In these areas, prebaked anodes also play a role in transferring current and heat, resisting oxidation, etc., to ensure the smooth progress of production.

In conclusion, prebaked anodes, as an important raw material for chemical production, have excellent properties and a wide range of uses. In the future chemical production, with the continuous advancement of technology and the expansion of application fields, the properties and uses of pre-baked anodes will continue to be optimized and developed.
