The raw material of electric furnace is composed of scrap steel, ferroalloy and loose material. The ratio of steel into the furnace is 95% scrap steel, and the remaining 5%. The scrap is added to the electric furnace less than three times through the rotary furnace cover, the maximum size of a single scrap:
2. Main technical features of electric arc furnace equipment:
The electric arc furnace equipment is open top charging, full hydraulic pressure, bottom steel, overhead arrangement.
Electric arc furnace adopts copper-steel composite conductive transverse arm.
Large section water-cooled cable is used for short network.
PLC electrode regulator ensures maximum accuracy and reliability of the electrode system.
Hydraulic system proportional valves are made from Rexroth or PARKER.
The transformer can be overloaded by 20% for a long time, and has sufficient mechanical strength to ensure that it can withstand frequent short-circuit impact.
The transformer is strong oil circulating water cooling (OFWF) and adopts faultless strong oil circulating water cooler.
3. Equipment use
This steelmaking furnace can use basic lining or acid lining for melting ordinary structural steel, high-quality steel and high-grade alloy structural steel (die steel, roll steel, gear steel, stainless steel, etc.).
