Abstract
A process for casting TiAl components, having the following process steps: producing a melt (S) of the TiAl material below an inert gas fill (IF); placing a casting mold () on a gate () in a gastight manner; flooding the casting mold () with inert gas (IG) by opening a closure mechanism () which is arranged at the gate () and is connected to an inert gas source (); pressing the melt (S) through the gate () into the casting mold () by increasing the pressure (P) of the inert gas fill (IF) above the melt (S) while at the same time evacuating the inert gas (IG) from the casting mold (), and stopping the inflow of inert gas (IG) as soon as it is determined that the melt (S) passes above the position of the closure mechanism ().
