Abstract

An electric arc furnace comprises a bottom, a roof and a side wall. The side wall is formed from a plurality of bimetal panels each having an inner copper face and an outer steel face. The roof may be formed with similar bi-metal panels. The hollow panels include internal baffles to define channels through which cooling water flows. The copper face is smooth and free of welds so as to maximize thermal heat transfer by the panels. The copper face enhances thermal efficiency and minimizes maintenance requirements of the panels, while the steel face reduces manufacturing costs of the panels.
