Electric Arc Furnace mainly used in smelting of high-quality carbonsteel, stainless steel, alloy-steel and other metals, which is the mainequipment for scrap smelting.
1. Electric arc furnaces is a furnace that heats the charged material by means of anelectric arc and electricity as the main energy sources.
2. The arc zone temperature can reach up to 3,000ºC ,the meltingtemperature more than 1700c.
3. Regardless of good quality steel scrap or poor, all can be charged
in EAF as feedstock, and achieve high quality steel (Such as carbonsteel can be charged in EAF to obtain stainless steel)
4. Output of Electric arc furnace much more than others scrap smelting furnace.

Strengths Of SR Electric Arc Furnace
1. Low power consumption
SR's large current system made of pure copper as conductive medium, the whole circuit with less resistance. Electrode arm shaped as copper-clad box type, resistance and heat can be reduced efficiently. Reasonable arrange of all conductive systems to minimize the resistance of every circuit.
2. Safety & Stability
Full set of hydraulic driving system equipped with accumulator to ensure stability of facilities in the operation process. Whist, equipments can go on the motion when there any emergency accidents happen.
3. Low electrode consumes
Electrode breaks in the process of melting brings huge economic losses and inconvenience. SR's patented <anti-break of electrode system> technology dramatically drops the possibility of electrode cracks in the operation.
4. High flexibility & Maximum simplicity of operation
HMI used in electrical automation control, interface simulates the real form of furnace, which make the operation more convenient. Mixing feedstock, charging feedstock, melting, tapping all the commands can be implemented by computer.
5.High arc forming efficiency
SR's patented technology < Precision regulating electrode >, utilizing multi signal acquisition, PLC signal contrast technology,shortening the formation time of electrode arc,so that to avoid long time arc formation influence the upper grid system. Different with traditional single signal return control technique.
6.Diversified dust removal system
SR's furnaces are equipped with a variety of dust removal systems, can be based on environmental requirements of different countries support different forms of dust removal equipments.
