Graphite Electrode Product
Product Description
Graphite electrodes are a type of conductive material made from high-purity graphite. They possess excellent electrical conductivity and chemical stability.Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, with coal tar asphalt as the binder. They are produced through processes such as calcination, batching, mixing, molding, baking, graphitization, and machining. They are conductors that are heated and melted by an electric arc in an electric arc furnace to release electrical energy. Depending on their quality indicators, they can be classified as RP graphite electrode, HP graphite electrode, and UHP graphite electrode.
Our company's graphite electrodes have the following advantages:
* High density, high temperature resistance, high mechanical strength and strong chemical stability.
* The surface can be treated with anti-oxidation.
* Corrosion resistance, strong acid and alkali resistance.
* Excellent thermal shock resistance, electrical conductivity and thermal conductivity.
* Strong wear resistance and lubricating performance.
* Long service life.

Application
Graphite electrodes, as an important industrial material, have a wide range of applications. The main application areas of graphite electrodes are as follows:
1.
Metallurgical field: Electric arc furnaces for steel production are the major users of graphite electrodes. In electric arc furnaces, current is introduced into the furnace through graphite electrodes, and the high-temperature heat source generated by the electric arc between the electrode tip and the furnace materials is utilized for smelting.
2.
Chemical industry: The electric arc furnace is mainly used for the production of industrial silicon and yellow phosphorus, etc. Its characteristic is that the lower part of the conductive electrode is buried in the furnace material, forming an electric arc within the material layer, and using the heat energy emitted by the material's own resistance to heat the material. Among them, the electric arc furnaces with higher current density require graphite electrodes.
3
.New energy sector: In lithium-ion batteries, artificial graphite is the main negative electrode material. With the widespread adoption of new energy vehicles, the demand for high-performance batteries is increasing day by day, which directly drives the demand for graphite electrodes.
4.
Semiconductor manufacturing: Graphite electrodes play a crucial role in the electron beam welding and sintering processes during semiconductor manufacturing, and are used to produce high-precision electronic components.
5.
High-temperature heat treatment: Graphite electrodes can be used to manufacture high-temperature heat treatment furnaces, which are employed for the heat treatment of metal materials.
6.
Electrical discharge machining: Graphite electrodes are gradually replacing traditional copper electrodes and have become the mainstream choice in related industries.
Company Profile
Shijiazhuang Nalai Biotechnology Co., Ltd Provide high quality Graphite electrode, Graphite electrode mainly petroleum
coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization,
machining, made of, can be divided into ordinary power, high power and high power, mainly used in steel smelting electric arc furnace and refining furnace smelting furnace, electric furnace steelmaking is the use of graphite electrode in furnace to import
he current, strong current in the lower electrode by gas arc discharge, use the heat generated by the arc for smelting.Graphite electrodes of different diameters are used according to the capacity of the electric furnace. For continuous use of the electrodes, the electrodes are connected by the threaded joint of the electrodes. The graphite electrode used in steelmaking accounts for about 70 ~ 80% of the total graphite electrode consumption.
Packaging & Shipping
Packaging of graphite electrodes:
1.Connection method: One end of the electrode has been connected to the connector and then packaged for shipment. The main function of the packaging: To protect the electrode from damage during storage and transportation, especially to prevent the threaded part from being damaged.
2.The electrodes and connectors are packed separately and transported individually.
