Dynamic Simulations of the Cake Growth and the Uniformity for the Slip Casting Process

Abstract

The computer simulation methods of cake growth properties were studied for the slip casting of alumina with gypsum mold. Based on the two-phase flow mixture model, mass conservation of water and maximum close-packed density theory, the numerical calculations were performed for the dynamical cake uniformity, cake density, mold thickness and effective applied pressure in this work. Good agreement was observed between the experimental experience and simulated cake uniformity with the different volume fractions of the slurry and the different sprue gate location conditions. The air-dried cake density and appropriate mold thickness can be estimated quickly by the present formulas. It is useful to simulate the dynamical cake properties with different process conditions which are difficult to detect.
