Electric arc furnace uses electricity as fuel source and utilizes the arc high temperature produced by electrode and furnace charge to heat and melt the furnace charge. It is widely using in production of normal steel, high quality carbon steel, various alloy steel, stainless, various ferroalloys. It is the key equipment in steel making factories, foundry factories, ferrous alloys making factories and etc.
Characteristic:
1, Smelting temperature is flexible to be controlled, to meet different steel grade production needs.
2, High heat efficiency, atmosphere inside furnace can be controlled.
3, Remove the phosphorus, sulfur, oxygen and other impurities and improve steel quality.
4, Easy to control the chemical composition of steel, stable and high recovery rate of alloys.
5, Equipment is simple and shorter technological process.
Adoption of new technology:
1, Optimization design
2, Tubular water cooled furnace wall and furnace lid
Eccentric bottom tapping (EBT)
Copper-steel combined electrode arm
3, Cluster type large sectional area water cooled cables
Optimize large current system structure (energy-saving type)
Proportional valves hydraulic system
Basic level (PLC) + procedure level ( Industrial control computer) Control system
Frequency control technique
