A method for reducing energy consumption per ton of steel in rolling process

Abstract

The invention aims to provide a method for reducing the steel rolling steel process energy consumption per ton steel. The method includes A. acquiring the historical data of the key parameters involved in the steel rolling process, and constructing a mathematical model of the tapping temperature and the energy consumption per ton steel; B. acquiring the key parameters in the real-time production to be used as the initial values of the key parameters; C. introducing the initial values of the key parameters into the mathematical model of the tapping temperature and the energy consumption per ton steel to obtain the predicted values of the tapping temperature and the energy consumption per ton steel; D. randomly optimizing the initial values of the key parameters to obtain the temporary optimized values of the key parameters, calculating the temporary optimized values of the tapping temperature and the energy consumption per ton steel, and determining the validity of the temporary optimized values; E. performing continuous cycle optimization until the regulated target values of the key parameters are obtained; and F. inputting the regulated target values of the key parameters into the steel rolling process control system to control the steel rolling process. The method overcomes the shortcomings of high reconstruction cost and bad control precision in the prior art and has the characteristics of stabilizing the tapping temperature and reducing the energy consumption per ton steel.
