Abstract

Procedure for melting and casting metals, especially noble metals and their alloys, in which the melt obtained, after opening a valve, is introduced through a closed communication channel into an evacuated and previously heated tank, characterized because the raw material melts inside a chamber that can be closed essentially pressure-proof, and because at least during bleeding the pressure of the gas mattress inside this chamber rises above the pressure outdoor atmospheric.
