Technological Advantages

Advantages of Sanrui Electric Arc Furnace Technology

1.Low power consumption reduces costs
   The high current system of the electric arc furnace uses pure copper as the conductive medium, and the overall circuit resistance is small. Taking into full consideration the skin effect when current passes through a conductor, the cross arm adopts a box shaped copper steel composite plate structure, which can effectively reduce the generation of resistance and heat on the side. Reasonable arrangement of high current system to reduce the impedance of various currents.

2.Safety and stability of electric furnace equipment
   The entire hydraulic drive system is equipped with an accumulator, which stabilizes the hydraulic system and ensures more stable operation of the equipment. At the same time, in the event of sudden accidents such as power outages, incomplete equipment operations can continue to be carried out, improving the safety of smelting.

3.Reduce electrode consumption
   The use of an anti electrode breakage system can effectively reduce the probability of electrode breakage during the smelting process. Especially in the process of melting scrap steel, avoiding electrode breakage is equivalent to saving an entire furnace of molten steel and reducing economic losses.

4.Easy to operate and convenient
   The electrical automation control adopts a human-machine interface, which simulates the real furnace body form and is easy to operate. Ingredients, feeding, smelting, and steelmaking can all be operated on a computer.

5.High arc initiation efficiency
Adopting a new type of electrode adjustment system, the electrode lifting control of the electric arc furnace breaks the traditional single signal return control technology. It adopts multi signal acquisition and PLC signal comparison technology to improve the electrode arc starting speed and avoid long-term impact on the upper level power grid system during the arc starting process of the electric arc furnace.

6.Diversified dust removal systems
Our dust removal systems are diverse and can be equipped with different forms of dust removal equipment according to the environmental requirements of different countries.
 

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.
