%X Grain refinement is a critical method to improve the mechanical and anti-fatigue properties of castings. Increasing the fraction of equiaxed grains can remarkably improve the ingot quality regarding solidification structure, particularly the center line segregation. The effect of low-frequency mechanical vibration (MV) on the solidification structure was investigated and evaluated by experimental methods using water model as well as hot ingot casting model and numerical modelling by using Finite Difference and Cellular Automaton methods. Experimental results of the water model are presented for the solidification of a 30
