MG make Electric Arc Furnace is a squat, cylindrical vessel made of heavy steel plates. It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof. The shell sits on a hydraulically operated rocker that tilts the furnace forward for tapping and backward for slag removal. The bottom—i.e., the hearth—is lined with tar-bonded magnesite bricks and has on one side a slightly inclined taphole and a spout, an oval hearth and a vertical taphole. With this latter arrangement, a furnace needs be tilted only 10° for tapping, producing a tight and short tap stream that decreases heat loss and reoxidation of the liquid steel. Before charging, the vertical taphole is closed from the outside by a movable bottom plate and is filled with refractory sand.
