Графитовый электрод UHP

UHP graphite electrode is mainly used for smelting scrap steel in eaf steelmaking production.

This is a process in which it is used as a high temperature resistant conductor, and three-phase alternating current is used as a power source. Электрические дуги are generated between  electrodes and metal materials, and then the high temperature of the arcs is used to heat and melt the furnace materials.

They are mainly used in DC electric arc furnaces, AC electric arc furnaces and ladle refining furnaces. 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 EAF steelmaking.

Raw materials for graphite electrodes -Needle Coke

Needle coke gets its name because its crushed particles are like elongated needles. It is a high-quality coke with pronounced anisotropy and a lustrous long-fiber structure. Their molecular structure is arranged orderly and has suitable graphitization properties. At the same time, it has many advantages, such as low thermal expansion coefficient, porosity, and electrical conductivity.

Therefore, игольчатый кокс is a key raw material in the production process of ultra-high power graphite электроды. The needle coke content of our UHP grade is 100%, and it determines the price of graphite electrode.

Основные характеристики

Устойчивость к высоким температурам: 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.

Низкое удельное сопротивление: The specific resistance of the electrode body is below 5.0g∕㎝³и сосок ниже 4,0 г∕㎝.³. At this time, the resistance to current is small, reducing power loss.

Высокая плотность: The overall structure has smaller porosity, reducing electrode consumption.

Хорошая электропроводность: 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.

Высокая механическая прочность: В процессе замешивания частицы кокса равномерно перемешиваются и прочно связываются. Поэтому прочность на изгиб и сжатие очень высока.

Малый коэффициент теплового расширения: Поскольку в процессе производства добавляется игольчатый кокс, заготовка легче графитизируется при высоких температурах выше 2000℃. Чем лучше степень графитизации, тем меньше коэффициент теплового расширения.

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.
