Title: (DE) Ofen zum Glühen von zu Coils gehaspelten Stahlbändern und Verfahren zum Glühen derselben
(EN) Furnace for annealing coiled steel strips or sheets, e.g. magnetic steel sheets has a plate on which a loose charge of heat-resistant molded bodies is applied
Abstract: front page image
(DE)

Die Erfindung betrifft einen Ofen zum Glühen von zu Coils (C1, C2) gehaspelten Stahlbändern oder -blechen, insbesondere zum Glühen von Elektroblech-Coils (C1, C2), mit einer Unterlegplatte (3, 4), auf welcher eine lose Schüttung (S) hitzebeständiger Formkörper (F) aufgebracht ist, auf der die Coils (C1, C2) stehen.


(EN)

Furnace for annealing coiled steel strips or sheets has a plate (3, 4) on which a loose charge (S) of heat-resistant molded bodies is applied. The coils stand on the coils (C1, C2) of steel strips. An independent claim is also included for a process for annealing coiled steel strips or sheets comprising placing the coils on the loose charge of heat-resistant molded bodies and annealing on a vertically directed coil axis. Preferred Features: The molded bodies are spherical and hollow and are made of a ceramic material, preferably corundum.
