4results about How to "Guaranteed heating quality" patented technology

The application relates to a rolling temperature control method and system of a heating furnace, and belongs to the technical field of heating furnace control. The method comprises the following steps: acquiring rolling line working condition parameters and actual furnace temperature; inputting the working condition parameters into a pre-trained LSTM neural network prediction model to obtain dynamic remaining rolling time in a future preset time period; defining a temperature response lag coefficient based on the actual furnace temperature, establishing a coupling relationship between the temperature response lag coefficient and the remaining rolling time, and taking the temperature response lag coefficient as a ratio of a time for the actual furnace temperature to reach a preset target temperature to a theoretical temperature reaching time; calculating a reference temperature based on a preset comprehensive radiation model of the furnace, determining a temperature compensation amount according to the coupling relationship between the temperature response lag coefficient and the remaining rolling time, adding the reference temperature and the temperature compensation amount to obtain a target temperature, and adjusting the temperature of the heating furnace to the target temperature. The application has the effect of improving the temperature control precision of the heating furnace.
