Abstract

The metal spray forming process was examined using the mathematical model simulation by Baosteel’s test and developed facilities. The mathematical model comprised of the probability and statistical analysis of the droplet mass behavior and predicted the shape and temperature distribution of the billet during the spray forming process.
