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. Method and device for heating a workpiece kes made of non-magnetic metal on the forging temp rature, the workpiece first in an electrical High-performance fission-type radiant heating furnace in one Preheating temperature is heated, which is significantly below the forging temperature is, and then the preheated Workpiece from the furnace directly into an induction heater brought coil and an inductive reheating up to the forging temperature is subjected.
