Abstract: An apparatus for melting metals in a vacuum chamber has a weir box (1), electron beam generators disposed above the weir box, and a crucible for the withdrawal of the melt flowing out of the weir box. A weir or sill is disposed in the trough athwart the length thereof, and it divides the trough into two basins and is situated underneath the one electron-beam source. The melt flowing from the one basin into the other runs in a thin film over the top of the weir or notch while the titanium nitrite in the melt is dissolved.

Abstract: A magnetic deflection system for a high-power electron beam with an expanding cross-section area is used for melting or vaporizing metallic materials. Saddle coils are provided which open in a direction of expansion of the electron beam. With the aid of these saddle coils large deflection speeds of the electron beam are obtained with small imaging errors and large deflection angles.

Abstract: The nominal position value for the impact point of an electron beam on a medium located in a crucible is input to a device having a screen on which the contours of the crucible are represented. Light pen means establish a plurality of nominal positions of impact of the electron beam within the represented contours of the crucible.
