Abstract
Disclosed herein is a roof for an electric furnace. The roof includes: a small-ceiling seating port (120) which has a small-ceiling seating surface (122) and a small-ceiling support surface (124) that extends from the small-ceiling seating surface inwards and downwards; and a large ceiling (130) which has an upper roof panel (132) that radially extends from the small-ceiling seating port at a downward inclination angle, a lower roof panel (134) disposed below the upper roof panel at a position spaced apart from the upper roof panel, and a side roof panel (136) connected to the upper roof panel and the lower roof panel. The upper roof panel is connected to the outer circumferential surface of the small-ceiling seating port, and the lower roof panel is connected to a lower end of the small-ceiling support surface so that the inclination angle of the lower roof panel can be increased.
