EAF Electrode Arms - Electric Arc Furnace

EAF Electrode Arms - Electric Arc Furnace

In modern industrial production, the EAF electrode arms is an indispensable equipment.

They are widely used in metallurgy, building materials, chemical industry and other fields. Their function is to convert electrical energy into heat energy, thereby heating and melting metals, glass and other substances.

The electrode cross arm is composed of three sets of copper-steel composite conductive cross arms, three sets of electrode clamping and releasing mechanisms and three conductive chucks. 

It is arranged in a triangle in space and is in the form of a cantilever. The front end of the middle-phase conductive cross-arm is in the same plane as the side-phase conductive cross-arm, and the rear end is higher than the side-phase conductive cross-arm. The electrode cross arm adopts a copper-steel composite conductive cross-arm full water-cooled structure. The three copper-steel composite conductive cross-arms are all box-type structures, and the core tube of seamless steel pipe is in the middle. and stiffness.

The copper-steel composite conductive cross arm is both the conductor of the electrode current and the support body of the electrode. Compared with the traditional conductive copper tube and cross arm, it has small impedance, light weight and good rigidity. 

In order to reduce the diameter of the electrode distribution circle, the front section of the two side phase cross arms is designed as an inwardly curved T-shaped structure.

The angle between the side phase and the middle phase can be made larger, and the distance between them can be made very small, so it can be easily Effectively reduce the diameter of the pole center circle of the electrode.



EAF Electrode Arms Characteristics

The electric arc furnace electrode arms needs to have the following characteristics:

1. High temperature resistance.

Since the electrode arm needs to withstand high temperature during operation, it must have high heat resistance to prevent deformation or burning.

2. High strength and rigidity.

The electrode arm of an electric arc furnace needs to withstand a large amount of electrical energy and mechanical pressure, so it must have sufficient strength and rigidity to ensure stable operation.

3. It has good electrical and thermal conductivity to ensure the transmission of electric energy and the heating effect.

4. Possess certain chemical stability and corrosion resistance to deal with various chemical substances and corrosive gases in industrial production.


With the continuous advancement of industrial technology and the continuous development of electric furnace electrode arms, there are now many new electrode arm materials and design solutions.

As an indispensable key equipment in industrial production, the EAF electrode arms can better meet the needs of modern industrial production and promote sustainable economic development only through continuous technological innovation and quality improvement.


The EAF electrode arms manufactured by Xi'an Hani mainly has the following advantages:

The use of hollow section, double-layer copper-steel composite board greatly reduces the skin effect, reduces the impedance, and improves the electrothermal efficiency.

The box-shaped structure with a hollow section and the internal water-cooling channel greatly enhance the strength of the cross-arm, which is conducive to the adjustment of the electrode movement without causing vibration and is conducive to the stability of the arc;

The weight is lighter than the traditional steel pipe cross arm, and the inertia is small, which is conducive to the frequent lifting and adjustment of the electrode.
