HP grafit elektrot

HP graphite electrode is used in a high-power smelting furnace and a low-load to medium-load ladle furnace. Electric arc furnace steelmaking is to introduce current into the steelmaking furnace through electrodes, and the strong current passes through the gas at the lower end of the electrode to generate arc discharge. Then heat generated by the arc is used for eaf steelmaking. It is suitable for High-power electric furnaces with high power, high voltage, and short angle.

HP graphite electrode for eaf steelmaking

It is made of high quality petroleum coke, needle coke, and coal pitch as raw materials. The product is calcined, extruded, roasted, impregnated, grafitize, and machined. With good electrical resistance and high mechanical strength. It can be used in DC and AC electric arc furnaces and ladle refining furnaces for smelting various steel alloy sheets.

It has low resistivity and good mechanical strength and can reduce energy consumption and increase production efficiency. During production, steelworkers can improve thermal efficiency and process stability by carefully controlling the power input to an Electric Arc Furnace (EAF).

Temel Özellikler:

- Yüksek yığın yoğunluğu
- Üstün ısı iletimi
- Göreceli yüksek elektrik iletkenliği
– High machining accuracy
- Daha hızlı ve daha verimli çalışma
- Daha uzun kullanım ömrü

Graphite electrode is essential for steelmaking in Electric Arc Furnaces (EAF). They control steelmaking parameters such as temperature, power input, and oxygen content.

Uygulamalar.

HP graphite electrodes are widely used in electric arc furnace ÇELİK ÜRETİMİ processes such as secondary refining, ladle metallurgy and continuous casting. Its allowed current density is 18-25A/cm².

Also, they are used in specialized applications such as vacuum refining and producing stainless steel, specialty alloys, and other high-value products.

Advantages.

It is a carbon-based material used as a good conductor during the smelting process. They are energized to generate an arc and use high temperatures to melt the charge.

They have high power capacity and can carry higher current densities than RP grade. It has thermal shock resistance and oxidation resistance, while reducing power consumption and saving energy.

It is also offer excellent machinability and thermal conductivity. Strong flexural strength, can withstand extreme temperatures without breaking. During the eaf steelmaking production process, heat is transferred into the furnace by relying on the thermal effect generated by electric current.

Lider bir şirket olarak China graphite electrode manufacturer, we supply competitive prices on premium quality to provide you with cost-effective solutions for your eaf smelting and casting needs.
