In this work pouring rate equation for cast iron in lost foam process was shown. For description of this phenomenon the motion dynamic equation was used. Pressure affecting the liquid cast iron surface was described using Bernoulli formulae. Numerical simulation results were analyzed with respect to permeability, refractory coating thickness and foamed polystyrene pattern density influence on pouring rate.
