To determine the temperature progression (Tm(t)) of a hot-rolled product (1) in a cooling section (5), a thermal-conduction equation of formula (I) is solved in a cooling-section model (4). In said equation, e represents the enthalpy, lambda represents the thermal conductivity, p stands for the degree of phase transition, rho represents the density, T represents the temperature of the rolled product at the rolled-product location and t represents the time.
