DescriptionMétallurgie du zinc - Coupe transversale d'un four belge à régénérateur Siemens d'Auby (p. 487).png |
Français : Four belge à régénérateur de Carl Wilhelm Siemens utilisé à Auby.
L'appareil n'y a pas été très efficace, notamment à cause de la chauffe trop violente des creusets inférieurs, directement exposés à la flamme. |
