We investigate the evolution of the chemical enrichment of the intra-cluster medium by applying a semi-analytic model of galaxy formation to N-Body/SPH non-radiative numerical simulations of clusters of galaxies (Cora 2006). The results of this hybrid model for a set of clusters of different masses contribute to the theoretical interpretation of recent observational X-ray data, which indicate a decrease of the iron content of the intra-cluster gas with redshift (Balestra et al. 2006).
