Графітовий електрод UHP

Заявки:

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.

Основні характеристики

Висока термостійкість: 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.

Низький питомий опір: The specific resistance of the electrode body is below 5.0g∕㎝³а вага соска не перевищує 4,0 г∕㎝.³. At this time, the resistance to current is small, reducing power loss.

Висока щільність: The overall structure has smaller porosity, reducing electrode consumption.

Хороша електропровідність: 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.

Висока механічна міцність: У процесі замішування частинки коксу рівномірно перемішуються і міцно з'єднуються. Тому міцність на вигин і стиск висока.

Малий коефіцієнт теплового розширення: Оскільки голчастий кокс додається в процесі виробництва, заготовка легше графітується при високих температурах понад 2000 ℃. Чим кращий ступінь графітизації, тим менший коефіцієнт теплового розширення.

Переваги:

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 needle coke in production to enhance the thermal shock resistance of the електрод 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.
