METHOD FOR PROCESS MONITORING DURING DIE CASTING OR THIXOFORMING OF METALS

摘要

The invention relates to a method for process monitoring during die casting or vacuum thixoforming of metals in a mold, wherein the time lapse of temperatu re (T) is continuously measured on at least one point of the system and the temperature progression of the system is calculated in real time using a program. The time lapse of the heat flow (W) is calculated from the temperature progression of the system and the time lapse of the energy (U) o f the system and the solidification heat portion (UE) of the metal solidified in the mold are calculated from the heat flow. At a given time, the calculated values are used as monitoring parameters.
