UHP700mm is used for steel smelting and silicon smelting

In the steel smelting process, UHP700mm graphite electrodes are used in electric arc furnaces (EAFs), which are commonly used for steel production. The UHP700mm electrode is capable of handling high currents and is suitable for the high energy consumption required in large-scale steel production. It plays a crucial role in generating and sustaining the arc, which reaches extremely high temperatures to melt scrap steel and other metal raw materials. The UHP700mm graphite electrode helps effectively melt and refine the raw materials, resulting in high-quality steel products.

UHP700mm electrodes are also applied in the silicon metallurgy process, particularly in submerged arc furnaces (SAFs). SAFs are typically used to extract metallic silicon from materials such as silica dioxide (e.g., quartz) and carbon (e.g., tar).The necessary electrical energy provided by UHP700mm electrodes is used to heat and melt the raw materials, thereby producing metallic silicon.

Application of UHP700mm in steel and silicon smelting

Steelmaking:

EAF is an important method for producing steel, especially suitable for recycling of scrap metal.

UHP700mm graphite electrode provides the required electrical energy to generate and maintain the arc in EAF.

The high temperature from the arc melts the scrap steel and other raw materials, thereby achieving production of high-quality steel products.

Silicon smelting:

UHP700mm graphite electrode is also used in metallurgical silicon smelting.

The arc generated by UHP700mm graphite electrode provides the high temperature required for metallurgical silicon smelting.

These electrodes facilitate material heating and melting, resulting in metallic silicon.

The main advantages of UHP700mm graphite electrode lie in its larger diameter and higher power capacity, making it suitable for heavy industrial applications such as steelmaking and silicon smelting.

Packing and shipping

UHP700 packaging is usually 1 piece/2 pieces per pallet, but it can also be customized according to customer requirements.
