Through the probability simulation method, the statistical model of mass metal liquid drop during metal spraying forming process was developed. By applying this model, great efforts were made in the study of ejecting process of molten steel during spray forming operation. The distribution of metal liquid drop and their initial velocity with different size and the original appear location of different size droplet during spraying forming were obtatined based on the above computation. Based on the statistical analysis of the large number of metal liquid droplets, the form ation and motion of liquid drop of whole space were defined in detail, providing the precondition and reference for further study on liquid drop deposit process in depostition plane.
