METHOD FOR FLOATING UP AND SEPARATING INCLUSION IN METAL

摘要

PURPOSE:To quickly enable float-up and separation of the whole non-metallic inclusions in a metal specimen by using a metal having the same composition as the aimed metal and beforehand removing the non-metallic inclusion as a flux. CONSTITUTION:At the time of floating up and separating the non-metallic inclusions in the aimed metal by electron beam melting, the metal substantially having the same composition as the aimed metal and beforehand removing the non-metallic inclusions is used as the flux. The aimed metal is melted together with the flux by the electron beam and the non-metallic inclusion in the aimed metal is floated up and separated without decomposition. The removal of the non-metallic inclusion in the metal used as the flux is desirable to execute by melting this metal with the electron beam and floating up and seaparating the non-metallic inclusions and removing the separated inclusions with decomposition, vaporizing and mechanical means.
