소개

Graphite electrode used for electric arc furnace and are important in many industrial processes. In this blog post, we will discuss the various advantages of graphite electrodes, including their high conductivity, corrosion resistance, and low resistance properties. Graphite electrodes can transmit electric current stably and efficiently. You can continue reading to learn more about the benefits of using graphite electrodes.

전기로용 흑연 전극은 매우 높은 온도에서 사용할 수 있습니다.

Graphite electrodes can withstand temperatures up to 3,500 degrees Celsius, making them ideal for high-temperature applications such as metal melting and refining. This makes furnace graphite electrodes reliable for working at extremely high temperatures.

In addition, its thermal conductivity is very high, comparable to metals such as aluminum and brass. The thermal conductivity of graphite is due to the vibration of electrons in the crystal, which creates heat transfer. In general, the thermal conductivity of graphite electrodes decreases with increasing temperature.

열팽창 계수가 낮습니다.

흑연 전극은 낮은 열팽창 계수, or CTE for short. It refers to the phenomenon that the length of a solid material increases with increasing temperature. CTE is an important quality indicator. Because the electrodes have to work at a temperature of 3000 ℃ or above, production requirements will increase or decrease the temperature.

At this time, it is required that the size of the conductor does not change significantly, and graphite electrodes meet this requirement. Its coefficient of thermal expansion is minimal compared to metals, and it will not crack or fracture due to temperature fluctuations. The higher the quality of the graphite electrode and the higher the degree of graphitization, the smaller its thermal expansion coefficient.

전기 전도성이 우수합니다.

전기로용 흑연 전극은 탄소 성분으로 인해 전기 전도성이 우수하여 전기를 효율적으로 전도할 수 있습니다. 또한 다른 소재에 비해 저항이 낮아 전력 서지로부터 탁월한 보호 기능을 제공합니다. 흑연 전극 는 부식에 강해 다양한 액체와 가스에 노출되어도 녹슬지 않아 열악한 환경에서 사용하기에 이상적입니다.

부식에 강합니다.

Graphite electrodes have strong corrosion resistance due to their unique structure and excellent physical and chemical properties. It consists of a unique molecular structure composed of layers of carbon atoms bonded together in a hexagonal lattice.

It can remain stable under high-temperature conditions or in corrosive or oxidizing gas and liquid environments. Examples include the high-temperature environments of electric arc furnaces, blast furnaces, or aggressive chemicals in chemical plants. It is highly corrosion-resistant and will not be corroded. This metal is incomparable.

저항이 낮습니다.

흑연 전극은 다음과 같은 특징이 있습니다. 낮은 전기 저항, which ensures efficient current transfer. To be precise, resistance is closely related to production materials and processes. Needle coke is added to the production of raw materials, and after roasting and graphitization, its physical properties, including electrical resistance, are enhanced.

Graphitization in the production process is particularly critical, a process of continuous power supply at a high temperature of about 2700 ℃. The method of intensive graphitization can significantly reduce the resistivity of the finished electrode.

Generally, the resistivity of graphite electrodes is not greater than 8.5-11.0μΩ·m.

탄성 계수가 낮습니다.

흑연 전극은 낮은 전도율로 잘 알려져 있습니다. 탄성 계수. 그래파이트 전극은 큰 변형이나 균열 없이 충격이나 진동을 흡수할 수 있습니다. 이는 전극이 약해지거나 손상되지 않고 다양한 조건을 견딜 수 있다는 점에서 큰 장점입니다.

또한 소재의 유연성과 강도로 인해 다른 금속이 고장 나거나 파손될 때 흑연 전극을 사용할 수 있습니다. 따라서 다양한 애플리케이션에서 다용도로 사용할 수 있습니다.
