(Page 195)<br />
Pumps: Located on the western end of the floor are the<br />
motor/pump assemblies for oxygen lance, fume hood, and stack<br />
cooling. The cooling water facilities for furnace number one are<br />
laid out linearly on a north-south axis just south of the storage<br />
bins. They consist of two 60 hp Allis-Chalmers motors, each<br />
driving a 450 gpm Wilson-Snyder pump for lance cooling, and three<br />
250 hp Allis-Chalmers motors, each driving a 2700 gpm Wilson-<br />
Snyder pump for fume hood and stack cooling. The cooling water<br />
facilities for furnace number two are laid out linearly on a<br />
north-south axis just north of the storage bins and consist of<br />
the same equipment described for furnace number one.<br />
c. Motor/Winch Drum Assemblies for Oxygen Lance<br />
Hoisting Rigs: Located opposite each of the cooling water<br />
facilities described above along the eastern end of the floor are<br />
the motor/winch drum arrangements for the lance hoisting rigs at<br />
each furnace. Each arrangement consists of two 19 hp<br />
Westinghouse D.C. motors connected to a gear drive and a winch<br />
drum.<br />
6. Flux Storage Floor: The 86'-0" wide x 225'-0" long flux<br />
storage floor is located on a steel framed platform 30'-6"<br />
directly above the weighing floor.<br />
a. Flux Conveyor Belt: A 24" wide, 2 00 ton per hour<br />
conveyor belt, manufactured by the Chain Belt Company, runs along<br />
the center of the floor for nearly its entire length. The<br />
conveyor belt is powered by a 2 0 hp motor. The belt is an<br />
extension of the covered conveyor leading from the flux handling<br />
building to the BOP shop.<br />
b. Tripper: Running on rails which straddle the raw<br />
material conveyor belt is a tripper manufactured by the Chain<br />
Belt Company. The tripper's chutes divert the material traveling<br />
along the conveyor through openings in the floor to its<br />
respective storage bin.<br />
c. Lance Hoisting Rigs: Two steel framed lance<br />
hoisting rigs per furnace are located along the eastern end of<br />
the floor above the lance opening in the fume hoods for each<br />
furnace.<br />
