Mini Electric Arc Furnace Manufacturer Sanrui EAF Technical Advantages
Low power consumption, reduced cost
The high current system of the electric arc furnaces uses pure copper as the conductive medium, and the entire circuit resistance is small. Taking into full consideration the skin effect when current passes through the conductor, the cross arm adopts a box-type copper-steel composite plate structure, which can effectively reduce the resistance and heat side generation. Reasonable high current system layout makes the current impedance smaller.
Efficient energy utilization
Compared with traditional fuel furnaces, arc furnaces have higher energy utilization. It uses electric energy to directly generate high temperature without heating metal materials through combustion. This direct power conversion can improve energy utilization efficiency and reduce energy waste.
Strong flexibility
Mini electric arc furnace are suitable for the smelting and processing of various metal materials. They can process scrap steel, scrap iron, scrap aluminum and other waste materials, and produce high-quality metal products. Its flexibility makes arc furnaces widely used in many industrial fields.
Simple & convenient operation
The electrical automation control adopts a human-machine interface, which simulates the real furnace form and is easy to operate. Batching, loading, smelting, and steelmaking can all be operated on the computer.
Environmentally friendly
Since the arc furnace has no combustion product emissions, such as smoke, waste gas and waste liquid, it has a lower environmental impact. This is also one of the important advantages of small electric arc furnace in waste treatment and environmental protection applications.
We are equipped with a variety of dust removal systems, and can match different forms of dust removal equipment according to the environmental protection requirements of different countries.

Mini Electric Arc Furnace Steelmaking Process
01
The basic process of EAF steelmaking furnace mainly includes the following steps:
02
Before steelmaking, it is necessary to clean the residual slag in the furnace and repair the furnace lining to ensure the smooth progress of the steelmaking process.
03
The scrap steel and other metal charge are loaded into the electric arc furnace as the main raw material for steelmaking.
04
Electric energy is input into the electric arc steelmaking furnace through graphite electrodes to generate electric arc as a heat source.
05
The high temperature of the electric arc is used to heat the charge so that it gradually melts into molten steel. In this process, auxiliary energy such as oil-oxygen injection, natural gas-oxygen or coal powder-oxygen may be used to accelerate the melting process.
06
Oxidant is added to the molten steel to remove impurity elements such as carbon and phosphorus in the molten steel through oxidation reaction, and the molten steel is heated and heated evenly. The main task of the oxidation period is to oxidize carbon and phosphorus in the molten steel, remove gas and inclusions, and heat the molten steel evenly.
07
After the oxidation period, reduction refining is carried out to remove oxygen and other impurity elements in the molten steel. The main task of the reduction period is to make reducing slag for diffusion, deoxidation, desulfurization, control chemical composition and adjust temperature. In the modern small electric arc furnace steelmaking process, the reduction period may adopt precipitation deoxidation as the main method and diffusion deoxidation as the auxiliary method to achieve the expected refining effect.
08
The refined molten steel is poured out of the EAF and enters the subsequent casting or rolling process.

The EAF furnace uses electricity as a heat source and can adjust the atmosphere in the furnace, which is extremely beneficial for smelting steel containing more easily oxidized elements. Using the high-temperature flue gas of the electric furnace, the raw materials are preheated 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 has been continuously reduced.
