Description
In 1953 a major expansion project to increase steel production at Jones & Laughlin Steel Corporation’s Aliquippa Works was undertaken. A new 44-inch blooming mill and its drive were installed, replacing a steam-engine drive mill that set many production records during its time. The installation process was accomplished in the remarkable time of 7 days and 14 1/2 hours of down-time. The 44-inch Blooming Mill was driven by four 3000-hp, 70 to 140-rpm, 750-volt, double-armature motors, arranged in tandem twin drive. The main drive motors drew their power from a motor-generator set (pictured here) consisting of four 3000 kilowatt, 750-volt, d-c generators, a 15-foot 10-inch diameter, 220,000 pound steel plate flywheel (left foreground), and a 9000-hp, 6600-volt, 360-rpm induction motor. The 44-inch Blooming Mill was shut down in October 1984.
