MODERNIZATION OF THE ELECTRIC DRIVE SYSTEM DIVERTER OF ICE-CLEAN COOLING INSTALLATION SLS №1 JSC URAL STEEL Litsin K.V., Ph.D. (Engineering), Associate Professor, e-mail: k.litsin@rambler.ru Kovalchuk T.V., Student, e-mail: tyatqq@gmail.com Novotroitsk Branch of the National University of Science and Technology «MISiS», 8, Frunze st., Novotroitsk, 462359, Russian Federation Abstract The use of frequency-controlled electric drives is a trend of time. Virtually all obsolete systems, regulated on the basis of systems with a DC motor, are a thing of the past. The induction motor has several advantages. The article proposes the modernization of the electric drive system of the diverter ice-clean cooling for the sheet rolling shop of JSC "Ural Steel" (Novotroitsk). Authors presented the description of the interlayer cooling interlocker. The kinematic scheme of the mechanism and its nominal data are given. Authors made choice of the motor and the frequency converter in accordance with the calculations and the necessary requirements for the electric drive of the diverter. Authors presented scheme for connecting the selected asynchronous motor to a suitable frequency converter. Keywords crate, frequency converter, diverter, electric drive.
