AN AUTOMATION SYSTEM FOR CONTROL AND ONLINE DIAGNOSTICS OF DRIVES IN FURNACE AREA OF STEEL PLANT

摘要

The present invention relates to an improved automation system for control and online diagnostics of drives in Furnace Area of merchant mill in a steel plant. More particularly, the present invention is directed to a centralized Programmable Logic Controller (PLC) and remote I/O (Input/ Output) based monitoring and control system for all six control drives/ mechanisms and parameters of furnace area, charging area, Motor Oil Cellar, Mill Oil Cellar, Ashlow system and furnace exit side all Solenoids mechanism. Display Boards has been customized to depict status of those signals and equipment that are required by the individual operator to carry out coordinated operation of the mill. HMI stations have been installed for display of large number of information for various mechanisms along with historical recording. HMI is also used for development and maintenance and provides interface with the existing LAN backbone of the plant thus providing a wider access and interface of data.
