Abstract: An improved containment fence for a roller conveyor type runout table used with a hot strip mill includes a plurality of vertically extending posts mounted in fixed relation to and outboard of the conveyor rollers along each side of the runout table with the posts each terminating in a top end spaced above the conveying path defined by the rollers, and a plurality of fence plate assemblies each including an elongated generally rectangular plate and a pair of rigid mounting brackets on and extending outwardly from one surface of each elongated plate one adjacent each end thereof for mounting the plates on the upper end of the upwardly projecting posts and adjacent the ends of the rollers of the conveyor, each plate assembly having a length to extend past the ends of a plurality of adjacent rollers on the conveyor, and the posts and mounting brackets supporting the plates in overlapping relation along the length of the conveyor with a downstream end of each elongated plate extending inboard of the upstream end

Abstract: A pollutant collection and exhaust system is provided in a battery of coke ovens for removal of atmospheric pollutants from the gases released at the time of discharge of coke from an oven. A coke guide carriage is provided with an exhaust hood which encloses the coke guide and extends over the transfer car thereby enshrouding the discharging coke and resulting fumes and smoke during the discharge operation. The exhaust hood is movable along the length of the oven battery. A stationary exhaust manifold extends along the battery in spaced relation above the oven exhaust hood. The exhaust hood is equipped with connecting means which are adapted to register in coplanar sealing engagement with selected gated openings in the manifold while simultaneously opening the selected gates. Pollutants are exhausted from the discharge site and conducted through the manifold and associated treating apparatus with draft induced by an exhaust means connected to the manifold and treating apparatus.
