400 mm graphite electrode is a cylindrical electrode product with a diameter of 400 mm, which is made of high quality graphite as raw material and processed by a specific process. It plays a key role in metallurgy, chemical and other industrial fields. As a conductive material, can withstand high temperature, strong current and other extreme conditions.
For all kinds of electrochemical and high-temperature melting process to provide stable power transmission and reaction environment support. It is an important part to ensure efficient and stable operation of industrial production.
Excellent electrical conductivity
It can efficiently transmit large currents to meet the demand for electrical energy in large-scale electrochemical or high-temperature melting processes in industrial production. And ensure the continuous and stable reaction.
Good high temperature resistance
It can still maintain structural integrity and stable performance under high temperature environment, such as in electric arc furnace steelmaking. It can withstand high temperature of thousands of degrees Celsius without obvious softening or deformation. And ensure the continuity of the production process.
High chemical stability
It has a certain tolerance to various chemical substances in the furnace. This reduces the electrode loss caused by chemical reactions, and extends the service life.
Moderate mechanical strength
It can withstand its own weight and various mechanical stresses in the installation and use process. It is not easy to break and damage, to ensure the safety and reliability of production.

In the iron and steel smelting industry
As a key component of electric arc furnace, it can produce a strong arc, convert electrical energy into heat energy. Quickly melt raw materials such as scrap steel, greatly improve the efficiency and quality of steel production. And meet the needs of construction, machinery manufacturing and other industries for a large number of high-quality steel.
In the smelting of non-ferrous metals
Such as the electrolytic production process of aluminum, copper and other metals, the graphite electrode as the anode can withstand the strong current and high temperature environment in the electrolytic process. While it ensures good electrical conductivity, promoting the reduction and deposition of metal ions. And realize the efficient extraction and refining of non-ferrous metals.
In the field of chemical industry
In some high-temperature electrochemical synthesis reactions, you can use 400 mm graphite electrodes as electrode materials to participate in chemical reactions. Promote the reaction, provide necessary conditions for the production of chemical products. And because of its chemical stability, it can reduce unnecessary chemical reactions with reactants and products, improve product purity and production efficiency.
