How long is the life of graphite anode?

The life of graphitized cathode is generally more than 3500 days, which is about 1/3 longer than that of graphite cathode. graphite anode are mainly made of petroleum coke as raw material and coal tar pitch as binder, which are made by calcining, batching, kneading, pressing, roasting, impregnation, graphitization and machining.

What are the uses of graphite anode?

1. Submerged electric furnace

The graphite anode are used in the submerged thermal electric furnace, mainly for the production of ferroalloy, pure silicon, yellow phosphorus, matte and calcium carbide, etc. It is characterized in that the lower part of the conductive electrode is buried in the charge, and the electric arc between the anti-static plate and the charge is generated. In addition to heat, heat is also generated by the resistance of the charge when the current passes through the charge.

Each ton of silicon needs to consume about 150kg of graphite anode, and each ton of yellow phosphorus needs to consume about 40kg of graphite anode.

2. Electric furnace steelmaking

graphite anode are mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite anode to introduce current into the furnace. A strong current generates arc discharge through gas at the lower end of the electrode, and the heat generated by the arc is used for smelting.

According to the capacity of the electric furnace, graphite anode of different diameters are used. In order to use the electrodes continuously, the electrodes are connected by electrode screw joints. graphite anode for steelmaking account for about 70-80% of the total amount of graphite anode.

What are the properties of graphite anode?

graphite anode mainly utilize the conductivity and stability of graphite. Graphite is a mixed crystal with a special structure, which not only has the characteristics of atomic crystals, but also molecular crystals and metal crystals.

In the layered structure of graphite, the atoms in the layer are covalent bonds, the bond energy is large, the melting point is high, and the properties are stable. There are large delocalized bonds in the layer structure and good electrical conductivity.

Therefore, when using graphite anode, its electrical conductivity, high melting point and thermal stability are used. In addition, the use of graphite anode utilizes its physical properties rather than its chemical properties.

What is graphite anode material?

Its main raw materials are stone tar, needle coke and coal pitch, etc. Compared with copper, graphite material has the advantages of less consumption, fast discharge speed, light weight and small thermal expansion coefficient, and is becoming the preferred material in mold production.
