A pollution control system for an electric furnace station which provides for noise abatement and the collection and discharge of pollutant gases during charging, refining and tapping stages of electric furnace operations. A housing surrounds the electric furnace which is sized so as to enable tilting of the furnace during tapping, the housing having movable sections to enable entry of charging means for the furnace and entry of personnel, with an exhaust means in the upper region of the housing. In addition, a tapping shield is provided having a supplementary exhaust system to remove pollutant gases during tapping and additive deposition. Air curtain or other means are provided to preclude escape of pollutants during charging of the furnace through the charging means.
