Graphite electrodes are critical to operating Electric Arc Furnaces (EAF). They conduct the high-voltage electrical current needed to heat and melt the raw materials inside, which can then be used for smelting or refining operations.
Therefore, 흑연 전극 are integral to producing iron, steel and other metals in electric arc furnaces. When the graphite electrodes are energized, an electric arc is created between them, heating the furnace shell and melting any metal or alloy placed within electric arc furnace.
전기 아크로에서 흑연 전극이 강철을 녹이는 공정
When an EAF is used to melt steel, the process begins with a piece of scrap metal being placed in the furnace.
Workers then connect the graphite electrodes to an external power source that provides alternating (AC) or direct (DC).
그런 다음 작업자는 전원을 켜고 전극의 흑연 끝과 고철 사이에 아크가 형성될 때까지 전류를 조정하여 금속을 용융 액체로 녹이는 강렬한 열을 발생시킵니다.
작업자는 전극을 통해 150,000암페어의 전기를 통과시킵니다. 전극과 전극 사이에 전기 아크를 만들어 흑연 전극 and the raw materials in the furnace, which causes heat to be produced.
전기 아크 퍼니스와 그 종류는 무엇인가요?
An electric arc furnace (EAF) is a specialized furnace that uses graphite electrodes to heat and melts scrap metal to produce high-quality steel.
According to the current characteristics, people divide electric arc furnaces into AC and DC electric arc furnaces. Heroult 가 전기의 발명 이후 1988년에 발명했습니다.
The emergence of electric arc furnaces has developed an alternative energy source for coal-based steelmaking. Electric arc furnace steelmaking enables economical recycling of scrap steel. It was ultimately making steel the most recyclable material in the world.
흑연 전극을 사용한 전기 아크 퍼니스 작업
Arc furnace electrodes conduct electrical energy from an external power source into the interior of the electric arc furnace, creating an intense heat. Usually, AC or DC electricity creates an electric arc between the graphite electrodes and the scrap material.
When the temperature reaches 5000 degrees Celsius, the high temperature melts the scrap metal into a liquid state.
그런 다음 제강공이 용광로에서 쇳물을 쏟아냅니다. 일반적으로 각 용광로에는 전극이 3개씩 3개 열로 배열된 9개의 전극이 사용됩니다. 작업자는 흑연 전극을 사용하기 위해 전류와 전압을 조정해야 합니다. AC electric arc furnace.
In addition, steel mill workers should use particular components such as cooling systems and shields.
Please ensure that the molten steel does not become too hot or contaminated during the process. This will help to ensure a successful output from the furnace.
The importance of graphite electrode in electric arc furnace
Graphite electrode has low resistivity and are excellent conductors for transferring electric current. The electrode with needle coke and good graphitization degree has better performance.
In addition, its thermal expansion coefficient is low and will not deform when the current gradient changes.
Another critical point is that it has high mechanical strength, and no bending or breaking will occur. Given these characteristics, it is well suited for high-temperature applications in electric arc furnace.
Other materials cannot be replaced, so graphite electrodes are essential in industrial production.
According to the different needs of electric arc furnace steelmaking, it has three types – RP, HP and UHP graphite electrodes.
Graphite electrodes work with Arc furnace
An Electric Arc Furnace (EAF) is a type of furnace that uses graphite electrodes to generate an electric arc to melt scrap metal. The EAF consists of a cylindrical steel shell lined with refractory materials.
The bottom of the furnace is made up of a tilting platform, which can tilt to pour out the molten metal. Workers insert 흑연 전극 into the furnace through holes in the top and connect them to a power source.
When the workers turn on the power, an electric arc will generate, which heats the scrap metal and melts it. The workers pour the molten metal from the furnace and cast it into desired shapes.
The process consumes the electrodes, and workers must replace the electrodes periodically. EAFs are commonly used to recycle scrap steel and are also used in producing specialty steel.
결론
흑연 전극 are used in DC or AC electric arc furnaces (eaf) to create an arc when current passes through it. Convert electrical energy into heat to smelt scrap steel or metal.
