Multi Functional Steelmaking Electric Arc Furnace

Product Specification

As a core equipment in the field of steel production, the multifunctional steelmaking electric arc furnace integrates advanced technology and innovative design concepts, aiming to efficiently and flexibly meet diverse steelmaking needs, injecting strong impetus into the development of modern steel industry. ​

Working principle:
The multifunctional steelmaking electric arc furnace mainly relies on three-phase AC power supply for operation. The current is precisely transmitted to the electrode system through a specially designed power supply system. High quality graphite material is often used for electrodes to ensure stable conduction of current and maintenance of arc stability under high temperature and high current conditions. During the entire steelmaking process, with the help of a high-precision electrode lifting control system, the electrode position is adjusted in a timely and flexible manner based on real-time reaction conditions and temperature changes in the furnace, thereby accurately controlling the arc length and achieving precise control over the size and distribution of heat input into the furnace. This meets the strict temperature requirements of different steel grades in each stage of the smelting process and ensures the quality of molten steel.

Structural design:
1. Optimize furnace structure: The overall design of the furnace is compact and sturdy, and the shell is made of high-quality heat-resistant stainless steel, which not only effectively resists high-temperature radiation, but also has excellent corrosion resistance, greatly extending the service life of the equipment. The internal lining can flexibly select alkaline, acidic or neutral refractory materials based on the smelting characteristics of different steel grades. For example, when smelting ordinary carbon steel, acidic refractory materials can meet the demand; The furnace cover adopts a fast opening water-cooled design, which facilitates the quick loading and unloading of furnace materials. At the same time, through circulating water cooling, the temperature of the furnace cover is effectively reduced, its durability is improved, and the continuity of the steelmaking process is ensured. ​
2. Precision electrode system: Three carefully crafted electrodes are arranged in an equilateral triangle with precise precision, vertically passing through the furnace cover and deep into the core reaction zone inside the furnace. The electrode is connected to a specially customized high-efficiency furnace transformer, which stably transmits electrical energy to the electrode through low resistance, high current carrying capacity cables and water-cooled conductive tubes. The electrode holder adopts high-precision design, which can firmly clamp the electrode and has good conductivity and heat dissipation performance, ensuring stable operation of the electrode under high temperature and high current conditions. In order to reduce the loss of electrodes during smelting, the electrodes are treated with special processes and have excellent conductivity, mechanical strength, and thermal shock resistance. The impurity content is strictly controlled to provide a stable and reliable heat source for steelmaking. ​
3. Intelligent mechanical control system: Focused on the convenience and accuracy of steelmaking operations, the multifunctional steelmaking electric arc furnace is equipped with advanced mechanical control systems. Install three high-precision electrode supports on one side of the furnace, each supporting a high-resolution electrode lifting column. The lifting column is equipped with a flexible horizontal electrode cross arm, and the water-cooled electrode clamp at the end of the cross arm can quickly respond to control system instructions and accurately adjust the electrode position. The electrode lifting column can capture subtle changes in the arc power inside the furnace in real time. With precise instructions from the intelligent automatic control system, the electrode position can be quickly and accurately adjusted to maintain stable arc length and ensure constant arc power input into the furnace throughout the smelting process, meeting the strict temperature stability requirements of different steel grades. In addition, there is a dedicated operating platform between the furnace cover and the electrode cross arm, which facilitates electrode connection and installation of the furnace top opening and closing mechanism. The operation is simple and efficient, significantly improving the convenience and efficiency of production operations. The control system also has remote monitoring and operation functions. Operators can monitor various parameters inside the furnace in real time and operate accurately through computer terminals in the control room far away from the furnace body, ensuring personnel safety.
