11.1 Melt characteristics of Heraenium alloys
11.1.1 Preparations:
Place ceramic crucible into the coil
Fill alloy into the crucible
Close chamber
11.1.2 Premelting (phase 1, 2, 3)
Press key “premelt”
Vacuum between 250 mbar
Observe heating process of the alloy (phase 1, 2, 3)
When phase 3 sets in press “Stop/back” key
11.1.3 Insert the casting mould
Open chamber
Position the casting mould
Close chamber
11.1.4 Main melt
Press key “main”; permanent observation of melting process by eyes (see phase 4, 5)!
Then select between “GS auto.” or “GS man.” (GS = casting)
In “GS auto” mode the delay time expires and the chamber is turned automatically
In “GS man.” mode the delay time expires, beep sound at “0”, timer continues counting until pushing the button
“turning”, which executes manual casting process
Heraenium CE:
Immediately turn casting chamber after reaching phase 6 (disappearance of the shadow) – key „turning“
