Sanrui EAF Technical Advantages
Low Power Consumption and Cost Reduction
The high current system of the mini electric arc furnace for sale uses pure copper as the conductive medium, and the entire loop resistance is small. Taking full account of the skin effect when current passes through conductors, the cross arm adopts a box-shaped copper-steel composite plate structure, which can effectively reduce resistance and heat generation. Reasonable high-current system layout makes various current impedances smaller.
EAF Equipment Operation is More Stable and Smelting is Safer
The entire hydraulic drive is equipped with an accumulator, which stabilizes the pressure of the hydraulic system and makes the equipment run more stably. At the same time, in emergencies such as power outages, the equipment can continue to perform unfinished operations, which improves the safety of smelting.
Electrode Consumption Reduced
The anti-electrode breakage system can effectively reduce the chance of electrode breakage during the smelting process. In particular, avoiding electrode breakage during the scrap melting process is equivalent to saving an entire furnace of molten steel and reducing economic losses.
The Equipment is Simple to Operate and Easy to Use
Electrical automation control adopts human-machine interface, which simulates the form of real furnace body and is easy to operate. Batching, loading, smelting and tapping can all be operated on the computer.
High Arc Starting Efficiency
Using a new type of electrode adjustment system, the foundry electric arc furnace electrode lifting control breaks the previous single signal return control technology and adopts multi-signal collection and PLC signal comparison technology to increase the electrode arc starting speed and avoid long-term effects on the electric arc furnace during the arc starting process. Upper level power grid system.

Electric Arc Furnace Steelmaking Process
01
The basic process of foundry electric arc furnace steelmaking includes slag removal, metal charging, power supply, melting, oxidation, reduction refining and tapping. Depending on the characteristics of the type of steel being smelted, there are different operating methods. The smelting process mainly consists of three phases: melting, oxidation, and reduction.

Depending on the characteristics of the type of steel being smelted, there are different operating methods. The smelting process mainly consists of three phases: melting, oxidation, and reduction.
03
During the oxidation period, measures such as early dephosphorization, intensive oxygen use, powder spraying to create foam slag, and rapid temperature rise can reduce the amount of oxidative decarburization from 0.3% in traditional processes to 0.1% to 0.15%, thus shortening the oxidation period by 50%. above.
04
In the reduction period, diffusion deoxidation in the traditional process is mainly replaced by precipitation deoxidation, and diffusion deoxidation is supplemented. White slag or carbide slag needs to be produced. Each furnace smelting takes 3 to 4 hours, and the power consumption is as high as 600 to 700kWh/t. Not only can the expected refining effect be achieved, but the steel quality is guaranteed and the reduction time can be shortened by more than 60%.
05
While improving the quality of molten steel, the process improvement has also increased productivity by about 20%, reduced power consumption by 10% to 15%, and reduced electrode consumption by about 8%, achieving considerable economic benefits.

After optimizing foundry electric arc furnace technology, Sanrui is one of famous small eletecrtic arc furnace manufacturers in China, Sanrui has achieved the best 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 electric energy into the electric arc steelmaking furnace through graphite electrodes, and uses the arc between the electrode end and the charge as the heat source for steelmaking.
The electric arc furnace uses electric energy as the heat source and can adjust the atmosphere in the furnace, which is extremely beneficial for melting steel types that contain more easily oxidized elements. Utilize high-temperature flue gas from electric furnaces to preheat raw materials through technology and equipment to achieve high efficiency, energy saving, environmental protection and high yield.
With the improvement of electric arc furnace equipment and smelting technology, and the development of the electric power industry, the cost of electric furnace steel continues to decrease. Nowadays, electric furnaces are not only used to produce alloy steel, but also to produce ordinary carbon steel and iron ore concentrate pellets.
