| Abstract: | This paper investigates the system functions and the order of effect of fac-tors on riser-casting-mold combination. Factors affecting feeding system are quantified on the basis of the theroical analysis by System Analysis. Implicitequations of size for riser and the laws of the shrinkage cavity profile in riserare developed with the help of the mathematical model of solidification processthat is derived from the porous media hydrodynamics. Tests have been carriedout to identify the feeding system functions and the order of factors affectingfeeding system are delieved. It provides the modeling basis for optimal designfor riser of insulation. |
