Conductive Cross Arm Introduction
The conductive arm of an electric arc furnace (EAF) is primarily composed of the front electrode conductive arm holder, a water-cooled clamping ring, the arm body, and the rear conductive copper plate.
Conductive Cross Arm Introduction
The conductive cross arm body is constructed from copper-steel clad plates or aluminum-steel clad plates, featuring a rectangular cross-section. It is internally cooled via water circulation, eliminating the need for water-cooled conductive copper tubes. This electrode conductive arms design serves to grip and support the electrode, while also transmitting electrical energy to the electrode for the purpose of heating and temperature elevation.
In electric arc furnaces and submerged arc furnaces, numerous insulating elements are situated between the electrode conductive holder and the conductive cross arm body, significantly simplifying the structure of the cross-arm and representing a novel type of celectrode arm for ultra-high power electric arc furnaces.
The conductive arm of an electric arc furnace (EAF) submerged arc furnace (SAF) primarily possesses the following advantages:
The utilization of a hollow cross-section and a dual-layer copper-steel composite plate significantly mitigates the skin effect, reduces impedance, and enhances electrothermal efficiency;
The box-type structure with a hollow cross-section, coupled with internal water cooling channels, significantly enhances the strength of the traverse arm, facilitating the adjustment of electrode movement without inducing vibration, thereby promoting arc stability;
The electrode cross arm is lighter in weight than the conventional steel pipe type, possessing a lower moment of inertia, which facilitates frequent elevation adjustments of the electrode.
The requirements for the conductive crossbeam are: lightweight, high stiffness, low impedance, and long durability.
The conductive crossbar is supported at one end on the pillar and, at the other end, it holds an electrode, and it is equipped with a lifting function.
The lightweight of the conductive crossbeam implies a corresponding reduction in the driving power required for the vertical adjustment of the electrode column, among other implications.
Conductive Cross Arm Supply
The electrode arms of the electric arc furnace's submerged arc furnace electrodes are fabricated from copper-steel clad plates and are cooled by water circulation.
All three copper-steel clad conductive arms are of a box-type structure and are subjected to forced water cooling to ensure adequate thermal strength and rigidity.
The electrode clamping devices are positioned within the arms and are of a rear-mounted configuration, allowing for the three phases to be freely interchangeable.
The clamping devices feature disc spring engagement, hydraulic cylinder release, and seal ring replacement through the extraction of the piston, without affecting the clamping state, thereby providing an optimal working environment.
The conductive cross arm of the electric arc furnace (EAF) is characterized by its operational reliability and is highly convenient for maintenance and adjustment.
Insulation is established between each phase of the electrode arm and the column, ensuring effective insulation protection between phases.
The insulation remains reliable under thermal operating conditions.
The connection between the column and the electrode arm employs a pre-tightened bolt system, allowing for minor adjustments at the assembly position to ensure the correct positioning of the three-phase electrodes.
The posterior segment of the mid-phase transverse arm is elevated, resulting in the entire short network being arranged in a spatial triangular configuration.
