Electrode Arm Assembly for EAF

The electrode arm assembly for EAF is made of a copper steel composite plate or aluminum steel composite plate. The cross-section shape is rectangular, and the interior is cooled by water. Many insulation links between the water-cooled conductive copper tube, electrode collet, and the cross arm are eliminated, which greatly simplifies the structure of the cross arm. It is a new type of conductive cross arm on an ultra-high power electric arc furnace.

1. Features of the Electrode Arm Assembly for EAF:

1.1 The product adopts copper steel composite plate welding to form an electrode arm assembly for EAF, in which the copper layer is used for conducting electricity and the steel layer is used to support various mechanical forces.

1.2 There is a water interlayer in the frame of the electrode arm, which is cooled by water and can withstand the burning of the water flame of the electric furnace.

1.3 The electrode clamping adopts the butterfly spring, which drives the hoop to hold the electrode tightly, and the form of pneumatic or hydraulic loosening. The clamping force is large, and the clamping electrode is reliable.

1.4 The electrode clamp adopts chromium copper alloy or copper steel composite plate, with internal water cooling and long service life.

2. Advantages of the Electrode Arm Assembly for EAF:

2.1 The hollow section and double-layer copper steel composite plate are adopted, which greatly reduces the skin effect, reduces the impedance, and improves the electric heating efficiency;

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

2.3 The weight is lighter than the traditional steel tube cross arm, and the inertia is small, which is conducive to the frequent rise and fall adjustment of the electrode.

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.

3. Requirements of the Electrode Arm Assembly for EAF:

The requirements for the conductive cross arm are lightweight, good stiffness, low impedance, and long service life. One end of the conductive cross arm is supported on the column, and one end holds the electrode, and has the lifting function. The light weight of the conductive cross arm means that the driving work of the electrode column for lifting and adjusting movement is relatively reduced, etc.
