Abstract
This invention relates to a shroud for a steel making electric-arc furnace which surrounds the electric-arc furnace main body for sound- and dust-proofing, having doors provided in the side wall of the shroud to permit the scrap bucket to move in and out of the shroud and an opening of a minimum width in the suction port of a dust collecting suction duct on the top wall to permit transverse movement of the bucket lifting means to the center of the electric-arc furnace main body.
