The invention relates to the technical field of
alloy die-
casting, and particularly discloses an
alloy die-
casting temperature field control method and
system capable of reducing hot cracks, temperature gradients of different areas of a die are adjusted in real time according to flowing and solidification characteristics of
alloy liquid, so that the surface temperature distribution of the die is matched with the solidification rate of the alloy liquid, and the alloy die-
casting temperature field is controlled. Utilizing a
machine learning
algorithm to predict a
risk area where hot cracks are generated on the basis of historical data and real-time
monitoring data, and dynamically adjusting the flow velocity of a cooling
system, the
heating power of a die or die-casting process parameters according to a prediction result; through dynamic
temperature gradient control, intelligent prediction and
feedback control, a cooling strategy, a stress release mechanism and a real-time monitoring and optimizing process, thermal
stress concentration can be effectively reduced, the possibility of generation of thermal cracks is reduced, the yield of castings is improved, the
cooling time of the castings can be shortened through the cooling strategy, and therefore the production efficiency is improved, and the production cost is reduced. And reworking and scrapping of castings are reduced.
