A Report on Automation of Convertor Tilting Drive Using Plc and Vvvf Drives
A REPORT ON AUTOMATION OF CONVERTOR TILTING DRIVE USING PLC AND VVVF DRIVES
Abstract: Industry is a home of various kinds of machines that are used for numerous processes and treatments. The control and working of these machines have been automated through the use of PLCs.
Automation has resulted in faster production rate, increased accuracy, better quality and reduced faults and human errors. PLCs and VVVF drives are used in most of the sections and units at VISL because of their simple methods of programming, energy saving and other advantages. The following report aims at suggesting improvement in basic oxygen furnace by automation of converter tilting drive using PLC and replacing the present motoring system by VVVF drives.
