electric arc furnace chemical for melting iron

Electric arc furnace mainly used in smelting of high-quality carbon steel,stainless steel,manganese and other metals,which is the main equipment for scrap smelting.

5t three-phase arc steelmaking furnace, the structure of removing the roof, then feeding from the top, tapping from tapping mouth, operating by right side. Mechanical Electrode lifting structure, furnace is tilting and furnace lid lifting, rotating by hydraulic, electrical control using PLC (Siemens) mediator control.

According to requirements, the steelmaking arc furnace can adopt alkaline or acid lining, and can smelt carbon steel, high-quality carbon steel, alloy steel, stainless steel and other varieties. The electric arc furnace equipment has the following main features:
▲ Electric furnace equipment adopt open the lid by rotating, top feeding, tapping from tapping mouth, semi-elevated layout.
▲ Copper composite conductive cross arm, and the overall is the way of column.
▲ Large cross-section water-cooled cable.
▲ The overall furnace shell, solid structure, good rigidity
▲ Furnace cover structure by water-cooled, long life
▲ Adopting the most advanced intelligent PLC electrode regulator at present, the maximum guarantee the accuracy and reliability of electrode automatic system.
▲ Electric furnace tilting and furnace cover rotation adopt hydraulic drive operation, improving smoothness and reliability of equipment.
▲ Hydraulic system and hydraulic pump, one for using, the other one is for preparing.
▲ Hydraulic tank is stainless steel fuel tank.
▲ Electrode automatic lift system with non-conductive transmitter device, to prevent the breaking of electrode.
▲ Transformers can be overloaded by 20%, with sufficient mechanical strength to ensure that they can withstand frequent short circuit shocks.
▲ Transformer for the strong oil circulating water (OFWF) adopts trouble-free oil circulating water cooler.
▲\tNo loading switch adopts electric control.

1、Low power consumption
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. 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
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
Our 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.
