The conductive cross arm is a cross arm made of copper-steel composite plate or aluminum-steel composite plate, which is an important accessory of the electric arc furnace.
Principle:
The conductive cross arm of the electric furnace is used to clamp and support the electrode, and transmit electrical energy to the electrode to heat it up.
Advantages of The Conductive Cross Arms:
1) The conducting transverse arm of the electric arc furnaces adopts a hollow section and a double-layer copper-steel composite plate, which greatly reduces the skin effect, reduces impedance, and improves the electric heating efficiency;
2) The box-type structure of the hollow section and the internal water cooling channel greatly enhance the strength of the cross arm, which is conducive to the movement and adjustment of the electrode without causing vibration, and is conducive to the stability of the arc;
3) The weight is lighter than the traditional steel tube cross arm, and the inertia is small, which is conducive to the frequent lifting and lowering of the electrode.

3. All threaded holes are embedded with stainless steel threaded sleeves, and bolts are made of 304 stainless steel material.
4. All water and oil pipes are made of stainless steel.
5. Welding adopts specific welding processes.
6. After welding, the quality-check water pressure is 0.8MPa, and there is no leakage after holding for 1 hour.
7. All welds are tested by UT. All welds shall pass UT testing.
8. Before leaving the factory, inspect the assembly dimensions of the three cross arms and evaluate whether the on-site usage data meets the requirements. After passing the inspection, proceed with exterior paint packaging.

Installation Instructions
Requirements:
The requirements for selecting conductive cross arms are usually: light weight, good rigidity, low impedance and long life.
The conductive cross arm of EAF is supported on the column at one end and clamps the electrode at the other end, and has the function of lifting and lowering;
The light weight of the conductive cross arm means that the driving work for the electrode column to perform lifting and lowering adjustment is relatively reduced, etc.
