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.
 
EAF steelmaking process
1, The basic process of electric arc furnace steelmaking includes slag removal and reheating, loading metal furnace materials, power transmission, melting, oxidation, reduction refining, and steelmaking. According to the different characteristics of the steel being smelted, there may be different operating methods, and the smelting process mainly involves three stages of operation: melting, oxidation, and reduction
2, With the continuous development of technology, the electric arc furnace steelmaking process has undergone significant changes. During the melting period, auxiliary energy sources such as oil oxygen injection, natural gas oxygen injection, or coal powder oxygen injection are used to accelerate the melting process. The melting time per furnace has been shortened by 15-20 minutes, and electricity consumption can be reduced by 50-60 kWh/t;  
3, In the oxidation period, measures such as early dephosphorization, enhanced oxygen consumption, powder injection to produce foam slag, rapid temperature rise, etc. can reduce the amount of oxidative decarbonization from 0.3% of the traditional process to 0.1%~0.15%, thus reducing the oxidation period by more than 50%.
4, During the reduction period, the traditional process of diffusion deoxidation is mainly replaced by precipitation deoxidation, with diffusion deoxidation as a supplement. White slag or carbide slag needs to be produced, and each furnace requires 3-4 hours of smelting, with a high electricity consumption of 600-700 kWh/t. Not only can it achieve the expected refining effect, but the steel quality is guaranteed and the reduction time is shortened by more than 60%.
5, The improvement of process ensures the quality of molten steel while increasing productivity by about 20%, reducing electricity consumption by 10% to 15%, and electrode consumption by about 8%, achieving considerable economic benefits.

8000kVA 180t Ferromanganese Production Use Electric Arc Furnace 10 Ton
   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.
