The deformation mechanism during the solidification was analyzed based on the experimental results ofthe castings. An approximate quadratic differential equation and its discrete model of calculation deflection were pro-posed. The model indicates that the key factors leading to the deflection deformation are the thermal bending mo-ment M and the flexural rigidity E.J. The smaller the former and the larger the latter is, the smaller the deflectiondeformation will be. The experiments are carried out at various technical conditions, and their results appear good a-greement with calculation ones. A method was proposed to predict and control the casting deformation.
