Systems and methods for computer-aided prediction of heat transfer coefficients during quenching and quenching of a casting

摘要

A method for computer-aided prediction of a distribution of heat transfer coefficients of a casting during a quenching process and for quenching a casting, comprising: a defined casting determined by a defined quenching process, a distribution of heat transfer coefficients of the defined casting and a temperature-time profile of the defined casting Casting is quenched, provided, and the temperature-time profile of the defined casting is determined experimentally by temperature measurements taken during the defined quenching process; simulating quenching a virtual casting simulating the defined casting with a simulated quenching process that mimics the defined quenching process; calculate a distribution of virtual casting heat transfer coefficients derived from the simulated deterrent process; simulating a heat transfer of the virtual casting with the calculated heat transfer coefficient distribution to determine a temperature-time profile of the virtual casting for at least a portion of the simulated quench process; the temperature-time profile of the virtual casting is compared with the temperature-time profile of the defined casting; the specific heat transfer coefficient distribution using a scaling factor ...
