EAF Power Conducting Arms

EAF Power Conducting Arms

The water-cooled composite EAF Power Conducting Arms for electric arc furnace, as the core part of the electrode lifting mechanism of modern electric arc furnace, is gradually becoming the preferred configuration of 5T-100T electric arc furnace and large tonnage ladle refining furnace with its unique rectangular beam structure design and excellent performance characteristics. The conductive Conductive Cross Arm is carefully welded by copper steel composite plate, which ingeniously integrates the two functions of conduction and support. The outer copper plate is responsible for conduction, and the inner steel plate provides a solid support, realizing structural simplification and efficiency improvement.

Compared with the traditional electrode Conductive Cross Arm, the water-cooled composite Conductive Cross Arm eliminates the complex conductive copper tube and insulation link, which not only simplifies the furnace bus bar structure, but also significantly increases the diversion area, effectively reduces the impedance value and reduces the maintenance workload. The symmetrical arrangement of the two side phase conductive Conductive Cross Arm relative to the middle phase conductive Conductive Cross Arm further optimizes the stability and symmetry of the arc and reduces the consumption of refractory.

The EAF Power Conductive Cross Arm is rich and fine in composition, including electrode spray ring, electrode hoop, electrode chuck, electrode soot blower, electrode clamping system, Conductive Cross Arm body, water inlet pipe, return pipe, oil inlet pipe, metal hose, water-cooled cable connecting plate and other parts, which together ensure the efficient operation and long-term durability of the conductive Conductive Cross Arm.

In terms of material selection, the EAF Power Conducting Arm is made of copper steel composite plate, and the copper plate is closely combined with the steel plate through explosive welding technology, which not only ensures the conductivity, but also enhances the structural strength. This design not only replaces traditional conductive copper pipes with copper plates, greatly increasing the conductive area, but also significantly reducing reactance and resistance values, improving active power output, and further enhancing production efficiency.

The characteristics of the EAF Power Conducting Arm are distinctive and prominent:

1. Efficient power input: improves production efficiency and meets the needs of high-intensity smelting.

2. Optimize impedance reactance: Improved electrical indicators and ensured stable combustion of the arc.

3. Good arc stability: The small pitch diameter reduces the loss of refractory materials.

4. High rigidity and fast adjustment: The electrode can be quickly adjusted, the system vibration is small, and the flexibility of operation is improved.

5. Effective cooling and insulation: ensure long-term stable operation of electrode Conductive Cross Arm.

6. Copper steel composite design: The copper layer is conductive and supported by the steel layer, balancing conductivity and mechanical strength.

7. Water interlayer cooling: The water interlayer inside the electrode arm frame effectively cools and resists the high temperature of the electric furnace flame.

8. Reliable electrode clamping: The butterfly spring drives and holds the electrode tightly, providing a strong clamping force to ensure the safety and stability of the electrode.

9. Long life electrode clamp: Made of copper alloy or copper steel composite plate, with internal water cooling, it extends the service life and reduces maintenance frequency.

In summary, the water-cooled composite conductive cross arm of electric arc furnace is gradually becoming an important component of modern electric arc furnace smelting technology due to its efficient conductivity, stable structural design, convenient maintenance method, and significant economic benefits.
