Abstract

Um heißes Stahlgut, dessen Temperaturmittelwert nur wenig unter der gewünschten Warmformgebungstemperatur liegt, dessen Kanten jedoch deutlich kühler sind als die mittlere Temperatur, wirtschaftlich auf Warmformgebungstemperatur nachzuwärmen, ist der Ofenraum eines Nachwärmofens (2) zumindest in einen Nachwärmzonenteil (6) und einen Aus­ gleichszonenteil (7) zweigeteilt, wobei in dem Nachwärmzo­ nenteil (6) die Brenner (38, 46) beim einlaufseitigen Ende (45) und der Rauchgasabzug (48) beim auslaufseitigen Ende (47) angeordnet sind, um ein Temperaturprofil (55) auszu­ bilden, bei welchem eine höchste Temperatur beim einlauf­ seitigen Ende (45) und eine tiefste Temperatur beim aus­ laufseitigen Ende (47) des Nachwärmzonenteiles (6) er­ reicht ist. To hot steel, whose temperature average is only a little is below the desired thermoforming temperature, however, its edges are significantly cooler than the middle one Temperature, economical at hot forming temperature is the oven space of a reheating oven (2) at least in a post-heating zone part (6) and an off equal zone part (7) in two parts, in the post-heating zone the burner (38, 46) at the inlet end (45) and the flue gas outlet (48) at the outlet end (47) are arranged to form a temperature profile (55) Form at the highest temperature at the inlet side end (45) and a lowest temperature when out running end (47) of the reheating zone part (6) is enough.
