Electric Arc Furnace Electrode Arm

The electric arc furnace electrode arm is the conductive cross arm.

It is made of copper-steel clad plate or aluminum-steel clad plate, the section shape is rectangular, the interior is cooled by water, and many insulation links between the water-cooled conductive copper tube, the electrode chuck and the cross arm are cancelled, so that the cross arm structure is greatly improved. A new type of cross-arm simplified on the ultra-high power electric arc furnace.

Principle

The principle of the electric arc furnace electrode arm

The conductive cross arm of the electric furnace is used to clamp and support the electrode, and transmit electric energy to the electrode to heat it up.

Advantages of electric arc furnace conductive cross arm

1. The hollow cross-section, double-layer copper-steel composite plate is adopted, which greatly reduces the skin effect, reduces the impedance, and improves the electrothermal efficiency;

2. 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;

3. 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.

Precautions:

As a main equipment of the electric arc furnace, there are certain requirements for the electric arc furnace electrode arm:

Light weight, good rigidity, low resistance and long life.

Because one end of the conductive cross arms is supported on the column, the other end clamps the electrode, and has the function of lifting. 

The light weight of the conductive cross arm means that the driving work of the up-and-down adjustment movement of the electrode column is relatively reduced and so on.
