Product Description
Electric arc furnace(EAF) is a furnace that heats charged material by means of an electric arc,used in foundries for producing cast iron products for secondary steel-making.
the electric arc furnaces are to be widely employed in mini steelworks project to form short-route steelmaking process with secondary refining furnace.
Our Electric arc furnace covers whole series products ranging from 4 ton to 300ton; Our electric arc furnace could be powered directly
From furnace transformer or powered by furnace transformer plus reactor, and
the later configuration is also called as High Impedance Electric Arc Furnace (HIMPEAF).
Features of electric arc furnaces are as follows:
1. Higher production rate because of UHP transformer long-arc melting and carbon-oxygen blowing technology;
2. Shorter tap-to-tap time,less than 60 minutes;
3. Conductive electrode arm is made of copper clad steel plate, reactance can therefore be reduced
4.Furnace shell is consisted of upper shell and lower shell, and water cooled panels are assembled on shell frame and furnace roof frame; This structure is beneficial to replacement of furnace shell by crane with lower lifting capacity
5. High current conductors of three phases are arranged in space In
triangular placement and so the arc powers of three phases are basically symmetrical; higher power factor and higher active power Can be obtained
6. Electrode regulating system has very high speed characteristic owing to operated by hydraulic system and controlled by proportional valves
7. All movements of furnace equipment are operated hydraulically,
8. The complete furnace equipment consists of mechanical high/low
