Benefits of our Small Diameter Graphite Electrode

• High Purity:

Our small-diameter graphite electrode typically has high purity and it has function of reducing impurities in the metal melting process.

• High density

Small-diameter graphite electrode’s high density enhances the strength and durability of the electrode, allowing it to maintain performance over a long period of use.

• High Thermal Stability:

Électrodes en graphite is structurally stable and not easily melted or oxidized at high temperatures.

• Ease of processing:

It can be machined into a variety of shapes and sizes to accommodate different EAF designs. This flexibility allows graphite electrodes to meet a wide range of metallurgical needs.

Applications

• Smelting calcium carbide and quartz:– In calcium carbide smelting, the small diameter graphite electrode acts as a conductor to introduce electrical energy into the furnace. So that the raw materials undergo chemical reaction to form calcium carbide, making the smelting process smoother. In quartz smelting, it plays the role of conduction and heating, helping quartz ore to be purified and converted at high temperatures.

• Mold Making:    -Small-diameter graphite electrode is used for processing all kinds of molds, such as injection molds, die-casting molds, etc. It enables precise EDM in complex shapes and small parts of molds, and improves the accuracy and surface quality of molds.

• Semiconductors : In the production of monocrystalline silicon, small-diameter graphite electrode can also be used to make heating element for crystal growth furnaces. Its high temperature resistance and chemical stability enables it to work in a high-temperature, high-vacuum environment. This provides the necessary conditions for the growth of monocrystalline silicon.

• Chemical:– In some chemical processes, such as electrolysis, synthesis reactions, etc.. You can use it as electrode material to participate in electrochemical reactions or provide conductive pathways.

• EDM:    – EDM is an important process in mold making. You can use small-diameter graphite electrode as tool electrode in EDM to remove mold material by discharge corrosion, resulting in complex shapes and high-precision molds. Its advantages include good discharge performance, low losses and high machining accuracy.

Why choose Jinsun graphite electrode for your smelting？

High Electrical and Thermal Conductivity:

-Our electrode has excellent electrical and thermal conductivity and can effectively conduct electric current and heat. This makes it excellent in the high-temperature melting process, able to transfer heat quickly, and improve melting efficiency.

High Temperature Resistance:

The electrode is stable at extremely high temperatures without melting or damage. Therefore, it has obvious advantages in high temperature environments such as electric arc furnaces, vacuum furnaces and medium frequency furnaces.

Low coefficient of thermal expansion:

The thermal expansion coefficient of graphite electrode is small, and it is not easily deformed by the heat generated during processing. So it can ensure the stability and accuracy of the smelting process.

Résistance mécanique élevée

Our electrodes can withstand high tensile and impact forces, and have a flexural strength of 10-45MPa. This is because these electrodes are impregnated multiple times to improve performance.
