CONVERSION OF ROTARY HEARTH FURNACE RELAY LOGIC TO PLC
In BHEL like companies, seamless tubes are extensively used in power stations, marine boilers, refineries, and for oil & gas exploration applications besides industries such as petrochemicals, fertilizers, textiles, automobiles, paper, sugar, etc.
Programmable logic controllers (PLCs) are nowadays becoming more popular in industrial process control applications because of the most of their advantages. The rotary hearth furnace (RHF) is one such unit used in industrial process, which requires more advanced control for its operation. In this project attempt has been made to automize the control function of Rotary Hearth Furnace in BHEL using PLC. This project deals with the design of the ladder logic from the relay logic for the Rotary Hearth Furnace unit through PLC.
The conversion of Relay logic to PLC has imparted good flexibility, fast implementation of changes in control program, easier trouble shooting, high speed operations and more reliability.
