Electrode Arms For EAF LF

1. Electrode arms is made of copper-steel composite plate or aluminum-steel composite plate;
2. The electrode chuck is made of copper alloy or copper-steel composite plate, which has a long service life;
3. 304 stainless steel material, durable and corrosion-resistant;
4. Rectangular beam design greatly reduces impedance value and maintenance workload;
5. Widely used in steelmaking furnaces, refining furnaces, etc.


Electrode Arms is the electric arc furnace conductive cross arm, which is made of copper-steel composite plate or aluminum-steel composite plate.

It is a new type of cross arm on the ultra-high power electric arc furnace that greatly simplifies the structure of the cross arm.

As a steelmaking electric arc furnace, accessories for ladle refining furnaces are widely in demand.



The conductive arms of the electric furnace are used to clamp and support the electrodes, and transmit electrical energy to the electrodes to heat them up.


The Composition of the Conductive Cross Arm

Electrode arms is composed of electrode spray ring, electrode hoop, electrode chuck, electrode soot blowing device, electrode clamping system, transverse arm body, water inlet pipe, return water pipe, oil inlet pipe, metal hose, and water-cooled cable connection plate.


Product Features

1. The product is made of copper-steel composite plates welded to form the electrode cross arm, in which the copper layer is used for conduction, and the steel layer is used to support various mechanical forces.

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

3. The electrode clamping adopts the form of butterfly spring, which drives to hold the electrode tightly, and starts or hydraulically releases it.The clamping force is large, and the clamping electrode is reliable.

4. The electrode chuck is made of copper alloy or copper-steel composite plate, with internal water cooling and long service life.


Electrode Arms Parameters

Conductive Cross Arm Body: 8mm copper+20mm Steel plate, 304 stainless steel for internal pipeline
Electrode Chuck (Contact fence): T2 copper forging
Clamp Click: 304 stainless steel (including metal hose, spherical union)
Connection Bolt: 304 stainless steel
Insulation: Mica material / epoxy resin material
Spray Device: stainless steel
Clamping Cylinder: With high-voltage insulating tubing



1. The use of hollow section and double-layer copper-steel composite plate greatly reduces the skin effect, reduces the impedance, and improves the electric heating efficiency;

2. The box-shaped structure of the 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 lowering of the electrode.
The conductive cross arm is a rectangular beam structure, which is welded by copper-steel composite plates.

Due to the cancellation of the conductive copper tube and many insulation links on the traditional electrode cross arm, the structure is simplified, the diversion area is increased, the impedance value and maintenance workload can be greatly reduced, and it can be widely used in 5T-100T electric arc furnaces and large-tonnage ladle, Refining furnace.
