Abstract: Specially shaped refractory bricks which form openings or channels through a wall formed therefrom are used in the sidewalls of electric arc furnaces adjacent the roof for the purpose of admitting cool room temperature air to sweep across and cool the roof. Means are provided for selectively opening and closing the channels whereby roof temperatures may be controlled in localized areas as needed. The channels are formed by abutting the side faces of the bricks which each have grooves therein. The grooves and thus the channels are tapered to permit easy removal of obstructions.
