Abstract (en)

[origin: WO2017191039A1] A method, furnace and software program for the controlled heating of a part comprising: obtaining a heating scheme defining a desired evolution of one or more indicators of the temperature of the part during heating in the furnace; providing the part to be heated in the furnace; three-dimensional digital modelling of the heating of the part, in real time and simultaneous to the heating of the part, the digital modelling using heating parameters of the furnace and a three-dimensional model of the part to be heated, and comprising predicting the one or more indicators of the temperature of said part for the next reference time; comparing the one or more indicators of the temperature of the part of said heating scheme with one or more indicators of the temperature of the part predicted by the digital modelling for the next reference time; and, following each comparison, adapting, if necessary, the heating parameters of the furnace depending on the result of the comparison, in order to reduce a difference between the one or more indicators of the temperature of the part of the heating scheme and the one or more indicators of the temperature of the part predicted by the digital modelling for the next reference time.
