AN AUTOMATED TEMPERATURE CONTROL SYSTEM FOR PREDICTING AND CONTROLLING TEMPERATURE IN A DECARBURIZATION AND/OR ANNEALING FURNACES OF SILICON STEEL MILL

摘要

An automated temperature control system for Decarburization and/or Annealing furnaces of silicon steel mill is disclosed. The control system comprises artificial intelligence module (Expert System) based on operating aspects including line speed of the steel in the furnace and the steel physical parameters including steel grade to resolve real time control problem, said artificial intelligence module activated an interference engine generating control parameters including predicted temperature routine for most appropriate thermal regime, Expert system having a PC based computing platform implementing for the decarburization zone and/or the annealing zone in the furnace, said artificial intelligence activated interference engine disposed in bidirectional data communication with PLC based control system of the furnace for receiving the line speed measured by the PLC sensors and downloading the predicted temperature routine to the PLC based control system for regulating heater means in the decarburization zone and/or the annealing zone for controlling the temperature in the decarburization zone and/or the annealing zone according to said predicted temperature routine.
