Model-based multicriterial optimization of electron beam melting and refining of copper

Abstract Experimental results on the quality of electron beam melting and refining of copper samples by implementing the “method of washers” are analyzed by using an empirical model estimation approach. The influence is studied of the process parameters – melting power and time of refining, on the residual content of impurities, the refining rate, the overall removal efficiency and the material losses. A graphical user interface is designed and developed for calculation, investigation and multicriterial optimization of the quality of the refined copper samples.
