UHP Grafit Elektrot

Uygulamalar:

UHP graphite electrode is mainly used for smelting scrap steel in eaf steelmaking production. As a high-temperature resistant conductor, it can easily melt various high-melting-point alloys in the arc temperature zone (up to 3000-6000 °C ) in the electric arc furnace connected to a three-phase transformer.

UHP graphite electrodes can also be used in ladle refining furnaces, continuous casting and other processes. The purpose of refining is to improve the quality of steel. This process uses the arc generated between the electrode and the molten steel to heat the electric arc furnace steelmaking. This will help steel mills achieve high production, high quality and low consumption.

Ana Özellikler

Yüksek sıcaklık dayanımı: It can withstand high temperatures during the electric arc furnace (EAF) steelmaking process. Even in harsh high temperatures up to 3600 degrees Celsius, it will not melt or deform or be damaged under the action of strong arcs.

Düşük özgül direnç: The specific resistance of the electrode body is below 5.0g∕㎝³ve meme başı 4,0 g∕㎝'ın altındadır.³. At this time, the resistance to current is small, reducing power loss.

Yüksek yoğunluk: The overall structure has smaller porosity, reducing electrode consumption.

İyi elektrik iletkenliği: They have low ash content, are heat-resistant and corrosion-resistant. Therefore they are excellent conductive materials used in electric arc furnaces at high temperatures.

Yüksek mekanik dayanım: Yoğurma işlemi sırasında kok partikülleri eşit şekilde karıştırılır ve sıkıca bağlanır. Bu nedenle eğilme ve basınç dayanımı yüksektir.

Küçük termal genleşme katsayısı: Üretim sürecinde iğne kok ilave edildiğinden, işlenmemiş ürün 2000°C'nin üzerindeki yüksek sıcaklıklarda daha kolay grafitleşir. Grafitleşme derecesi ne kadar iyi olursa, termal genleşme katsayısı o kadar küçük olur.

Advantages:

The resistivity of UHP graphite electrode is the lowest among all electrode types. This means that it can pass higher density current without breaking or deforming during arc furnace smelting.

Jinsun uses iğne kola in production to enhance the thermal shock resistance of the elektrot itself. This makes it have a lower thermal expansion coefficient and can better resist rapid changes in temperature without being damaged.

The density of the double-impregnated UHP graphite electrode has been greatly improved. So, even at high temperatures, it oxidizes slowly, reducing the number of replacements.

Its diameter can be more than 750mm, which can meet the smelting needs of 100MT ultra-high power arc furnaces.

UHP Graphite Electrode Price.

It is important to note that the price of it may vary due to market conditions, supply and demand dynamics, and other external factors. In addition, the rising cost of raw materials such as needle coke has also driven the price.
