HP-Graphitelektrode

HP graphite electrode is produced using high quality petroleum coke, needle coke, and coal pitch as raw materials. Then the product is calcined, extruded, roasted, impregnated, graphitized, and machined.  So its has 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).

Wesentliche Merkmale:

– High bulk density
– Superior heat conduction
– Relative high electric conductivity
– High machining accuracy
– Faster and more efficient operation
– Longer lifespan

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

Applications.

HP graphite electrodes are widely used in electric arc furnace Stahlwerk 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 eaf steelmaking process. The electrode energized to generate an arc and uses 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, so it 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.

As a leading  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.
