Abstract
The present disclosure provides a method for collecting parameters for casting solidification simulation and a gridded design method for a pouring and riser system, comprising calculating thermodynamic parameters of a superalloy; obtaining cooling curves of the superalloy with different thickness; measuring a linear expansion coefficient of the superalloy as a function of temperature; the design method comprising: simulating a solidification process with tubular features of different thickness, and determining a feeding distance of the features of different thickness; establishing a gridded pouring and riser system, dividing the casting into a plurality of modules according to the thickness, and dividing a cell inside each module, and ensuring that a size of the cell is less than the feeding distance with the thickness; simulating filling and solidification of castings and the gridded pouring and riser system, and analyzing simulation results of defects.
