U.S. STEEL DUQUESNE WORKS HAER No. PA-115 (Page 195) Pumps: Located on the western end of the floor are the motor/pump assemblies for oxygen lance, fume hood, and stack cooling. The cooling water facilities for furnace number one are laid out linearly on a north-south axis just south of the storage bins. They consist of two 60 hp Allis-Chalmers motors, each driving a 450 gpm Wilson-Snyder pump for lance cooling, and three 250 hp Allis-Chalmers motors, each driving a 2700 gpm Wilson- Snyder pump for fume hood and stack cooling. The cooling water facilities for furnace number two are laid out linearly on a north-south axis just north of the storage bins and consist of the same equipment described for furnace number one. c. Motor/Winch Drum Assemblies for Oxygen Lance Hoisting Rigs: Located opposite each of the cooling water facilities described above along the eastern end of the floor are the motor/winch drum arrangements for the lance hoisting rigs at each furnace. Each arrangement consists of two 19 hp Westinghouse D.C. motors connected to a gear drive and a winch drum. 6. Flux Storage Floor: The 86'-0" wide x 225'-0" long flux storage floor is located on a steel framed platform 30'-6" directly above the weighing floor. a. Flux Conveyor Belt: A 24" wide, 2 00 ton per hour conveyor belt, manufactured by the Chain Belt Company, runs along the center of the floor for nearly its entire length. The conveyor belt is powered by a 2 0 hp motor. The belt is an extension of the covered conveyor leading from the flux handling building to the BOP shop. b. Tripper: Running on rails which straddle the raw material conveyor belt is a tripper manufactured by the Chain Belt Company. The tripper's chutes divert the material traveling along the conveyor through openings in the floor to its respective storage bin. c. Lance Hoisting Rigs: Two steel framed lance hoisting rigs per furnace are located along the eastern end of the floor above the lance opening in the fume hoods for each furnace. d. Quenchers: See description VI - A below. C. Near Western Teeming Aisle: The near western teeming aisle is 64 , -5 11 wide x 525'-0" long.

A combination narrow and standard gauge track set upon the floor alongside the platform runs its entire length. 2. Teeming Ladles: Four 175-ton teeming ladles are located on the eastern side of the aisle near its northern end. Construction date of BOP shop: 1963. Construction of 200'-0" extension to northern end of charging aisle: 1976. Installation of all equipment within building: 1963. V. Clean Steel Production Building: Laid out on a north-south axis, the clean steel production building is an extension to the northern end of the BOP shop's near western teeming aisle. Constructed by the American Bridge Company, it is a 64*~5" wide x 200'-0" long x 80'-0" high steel framed, corrugated metal clad building, built on a concrete foundation. The building's gable roof is supported by Fink trusses.
