Improving arc input power by minimizing three phases impedance unbalance
This structure has a simple design to give top priority to maintainability. The arm is made of aluminum alloy to reduce the weight and improve the electrode responsiveness in ascent and descent, contributing to the improvement of the steel making unit consumption.
Water-cooled copper panel (NECT)

Great reduction of refractory unit consumption
Steel and pipe materials are employed for the upper part of the furnace wall and the lower slag line is made of pure copper. Near the slag line, Super NECT (made of pure copper forged) is employed to realize long life.
Jet burners(JB)

NIKKO is the pioneer of Oxy-Fuel Burner System for EAF.
Various type of burners are available to meet EAF operation such as FA burner, EBT burner and Slag door burner. NIKKO's Hybrid Burner is achieving good performance for scrap melting and cutting, heating up of molten steel by the effect of slag forming. Possible to select the fuel such as liquid fuel (Kerosine) or gas (LNG)
ACT
