Description
Construction workers installing a new drive motor rotor during the major expansion project to increase steel production at Jones & Laughlin Steel Corporation’s Aliquippa Works. 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, motor-generator sets, controls, and switchgear were all housed in a 191 foot by 68 foot motor room, which included a down-draft recirculating ventilation system. The 44-inch Blooming Mill was shut down in October 1984.
