Abstract (en)

[origin: DE19717615A1] The invention relates to a method for cooling metals in a steel works. According to the method, the cooling is adjusted in accordance with the temperature of the metal in order to bring the metal to a desired temperature. The temperature of the metal is determined or estimated in advance, by means of a temperature model. The parameters of said temperature model, especially the heat transmission coefficients and the heat conductivity of the metal are adjusted by means of genetic algorithms to take into account the properties of the metal and the cooling, with the aim of optimization.
