A hood assembly for use with a metallurgical converter is disclosed. The hood assembly comprises a hood resting on a supporting structure and having sidewalls the lower ends of which extend downwardly to a short distance from the apron plate of the converter and around a portion of the periphery of the converter corresponding to the angular movement of the mouth of the converter from the blowing to the charging position, and the upper ends of which follow a curve-linear or straight path extending from the upper back end of the hood until it meets with the lower ends of the sidewalls at the front of the hood, and a roof bridging the sidewalls except for an opening at the front of the hood extending over the mouth of the converter in the charging position. A gate extends over the opening in the roof of the hood and a pair of lifting arms are located on each side of the hood for pivoting the gate in a convex curved path from a closed position over the opening in the roof to an open position over the roof of the hood.
