Abstract
Verfahren und Vorrichtung zum Erhitzen eines Werkstüc
kes aus nichtmagnetischem Metall auf die Schmiedetempe
ratur, wobei das Werkstuck zunächst in einem elektrischen
Hochleistungs-strahlungswärmeofen vom Spalttyp auf eine
Vorwärmtemperatur erhitzt wird, die wesentlich unterhalb
der Schmiedetempertur liegt, und dann das vorgewärmte
Werkstück aus dem Ofen unmittelbar in eine Induktionsheiz
spule gebracht und einer induktiven Nacherhitzung bis auf
die Schmiedetemperatur unterworfen wird.
