Product Description

Product Description

       

    The conductive cross arm body is composed of copper steel composite plate or aluminum steel composite plate, with a rectangular cross-section. It is internally cooled through water circulation, without the need for water-cooled conductive copper pipes. This electrode conductive arm is designed to clamp and support electrodes, while also transmitting electrical energy to the electrodes for heating and temperature elevation purposes.
       The conductive arm of the electric arc furnace is mainly composed of a front electrode conductive arm bracket, a water-cooled clamping ring, an arm body, and a rear conductive copper plate.

    In electric arc furnaces and submerged arc furnaces, a large number of insulation components are installed between the electrode conductive support and the conductive cross arm, greatly simplifying the structure of the cross arm, making it a new type of ultra-high power arc electrode arm. furnace.

EAF Advantages

   1.By using hollow cross-section and double-layer copper steel composite plates, the skin effect is significantly reduced, impedance is lowered, and electric heating efficiency is improved;
   2.The hollow cross-section box structure, combined with internal water-cooled channels, significantly enhances the strength of the transverse arm, making it easy to adjust electrode movement without causing vibration, thereby improving arc stability;
   3.The electrode crossbar is lighter in weight and has a lower moment of inertia compared to traditional steel tube structures, which is beneficial for frequent height adjustment of the electrode.
   4.The requirements for conductive crossbeams are: lightweight, high stiffness, low impedance, and long durability.
   5.One end of the conductive crossbar is supported on the column, and the other end is fixed with an electrode and has a lifting function.
   6.The lightweighting of conductive crossbeams means that the driving power required for vertical adjustment of electrode columns is correspondingly reduced.

Electrode arm power supply

The electrode arm of the electric arc furnace's ore blast furnace electrode is made of copper steel composite plate and cooled by water circulation.

The three copper ladle conductive arms all adopt a box structure and are forcibly water-cooled to ensure sufficient thermal strength and rigidity.

The electrode clamping device is located inside the arm and adopts a rear configuration, allowing for free exchange of three phases.

The clamping device has the characteristics of disc spring engagement, hydraulic cylinder release, and replacement of sealing rings through piston extraction, which does not affect the clamping state and provides the best working environment.

The conductive cross arm of an electric arc furnace has the characteristics of reliable operation, easy maintenance and adjustment.

Establish insulation between the electrode arm and each phase of the column to ensure effective insulation protection between phases.

Insulation remains reliable under hot operating conditions.

The connection between the column and the electrode arm adopts a pre tightened bolt system, which allows for fine-tuning at the assembly position to ensure the correct positioning of the three-phase electrodes.

The rear section of the middle horizontal arm rises, causing the entire short network to be arranged in a spatial triangular configuration.

Services provided by SanRui

 

   After optimizing the electric arc furnace technology, Sanrui has achieved the optimal balance between raw materials, scrap preheating, energy conservation and environmental protection, smelting process control, automation control, smelting cycle, and production capacity. The electric arc furnace inputs electrical energy to the electric arc steelmaking furnace through graphite electrodes, using the arc between the electrode end and the furnace charge as the heat source for steelmaking.
   Electric arc furnaces use electrical energy as a heat source and can adjust the atmosphere inside the furnace, which is extremely advantageous for melting steel grades containing more easily oxidizable elements. By utilizing high-temperature flue gas from electric furnaces and preheating raw materials through technology and equipment, high efficiency, energy conservation, environmental protection, and high yield can be achieved.
   With the improvement of electric arc furnace equipment and smelting technology, as well as the development of the power industry, the cost of electric furnace steel continues to decrease. Nowadays, electric furnaces are not only used for producing alloy steel, but also for producing ordinary carbon steel and iron concentrate pellets.
