Often the temperature measurement in a rolling mill furnace is ignored. So long
as the billets don't come out of the furnace too cold, the fireman is usually not
too concerned about the temperature inside the furnace. This often causes unnecessary
super heating of the billets, leading to higher energy consumption.
The Fykays Furnace Temperature Control System is an automated System works to keep
the furnace temperature within a particular range so as to keep energy costs and
other losses in control.
Temperature monitoring and control by sensing soaking zone temperature and regulating
the air and fuel control valves by means of a PID controller, which can be either
pneumatically or electrically actuated. The air : fuel ratio is built into the controller
software. One of the noteworthy features of the temperature loop is the special
facility provided for manual intervention – on occurrence of a mill breakdown, the
furnace temperature can be turned down to pre-determined levels simply at the click
of a button.
