U.S. STEEL DUQUESNE WORKS HAER No. PA-115 (Page 145) apart, are located 18'-2" off of the north stockhouse*s eastern wall. The centerline of the northern most coke bin is 66'-3" off the northern wall of the stockhouse. The southern most coke bin is located directly over the inclined vibrating coke screen. b. Coke Feeder Conveyors: Attached to each of the coke bins at their bottom opening is a 42" x 72" electromagnetic feeder conveyor, manufactured by the Jeffrey Company, with a capacity of 115 tons per hour. c. Coke Conveyor Belt: The 60" x 55'-0" long motor powered coke conveyor belt (capacity = 200 feet per minute) is laid out on a north-south axis directly below the feeder conveyors. It runs in a southerly direction. d. Vibrating Coke Screen: A motor-driven Hewitt-Robins inclined vibrating coke screen with a capacity of 230 tons per hour is located at the southern end of the coke conveyor belt. e. Coke Weigh Hopper: A 6-ton coke weigh hopper is located south of and below the incline vibrating coke screen. 5. North Stockhouse Flux Delivery System: The north stockhouse flux delivery system transferred limestone or dolomite from flux bins suspended from a trestle to the 400 cu. ft. capacity skip car located in the skip pit. Installation Date: 1962. a. Flux Bins: Laid out on a north-south axis, two 8,000 cubic feet capacity flux bins, spaced 17'-9" apart, are located 18'-2" of the eastern wall of the north stockhouse. The centerline of the northern most flux bin is located 26'-7 1/2" off of the northern wall. b. Flux Feeder Conveyors: A 540 ton per hour capacity, 48" x 111" Jeffrey electromagnetic feeder conveyor is attached to each flux bin at its bottom opening. Each conveyor is laid out on a east-west axis. c. Flux Conveyor Belt: A 48" x 120'-0" long flux conveyor belt (capacity = 296 feet per minute) is located to the east and below the flux bins, 36*-5" off of the eastern wall of the north stockhouse. The belt travels in a southerly direction. d. Miscellaneous Weigh Hopper: A miscellaneous weigh hopper with a capacity of 30 tons is located below the flux conveyor belt at its southern end. 6. North Stockhouse Iron Ore Pellet Delivery System: The
U.S. STEEL DUQUESNE WORKS HAER No. PA-115 (Page 146) north stockhouse iron ore pellet delivery system transferred iron ore pellets from trestle hung pellet bins to the 400 cu. ft. skip car located in the skip pit. Installation Date: 1962. a. Iron Ore Pellet Bins: Four 6000 cu. ft. capacity iron ore pellet bins, spaced 17'-9" apart are laid out on a north-south axis 45*-2" off of the eastern wall of the north stockhouse. The centerline of the northern most pellet bin is located approximately 83'-0" off of the northern wall. The southern most pellet bin is located directly over the miscellaneous weigh hopper. b. Pellet Feeder Conveyors: A 540 ton per hour, 48" x 111" Jeffrey electromagnetic feeder conveyor, laid out on a east- west axis, is attached to each iron ore pellet bin at its bottom opening. c. Iron Ore Pellet Conveyor Belt: A 48" x 60'-0" long conveyor belt (capacity - 296 feet per minute) is located to the east of, and below the iron ore pellet bins, 36 , -5" off of the eastern wall of the stockhouse. The belt runs above the flux conveyor belt in a southerly direction. 5 - d. d. Miscellaneous Weigh Hopper: See description V - A - 7. North Stockhouse Sinter, Sinter Fines, and Scrap and Scale Delivery System: This system transferred the designated raw material from trestle hung bins to the 4 00 cu. ft. capacity skip car located in the skip pit. Installation Date: 1962. a. B_ins: Two 6000 cu. ft. capacity sinter bins, one 6000 cu. ft. capacity sinter fines bin, and one 3000 cu. ft. capacity scale and scrap bin, laid out on a north-south axis, are spaced 17 f -9" apart. Located 45 , -2" off the eastern wall of the north stockhouse, the sinter bins are the northern most bins with the scrap and scale bin located at the southern end. The centerline of the northern most sinter bin is located 8 f -10 1/2" off of the northern wall. b. Feeder Conveyors: Attached to each of the bins at their bottom opening is a Jeffrey electromagnetic feeder conveyor which is laid out on a north-south axis. The sinter bins are each equipped with a 594 ton per hour, 48" x 111" feeder conveyor. A 450 ton per hour, 36" x 72" feeder conveyor is attached to the sinter fines and scrap and scale bins.
