Abstract
La présente invention est relative à une installation de recuit continu pour tôles, particulièrement intéressante dans le cas des aciers doux pour emboutissage. L'installation est caractérisée en ce qu'elle comprend un four de survieillissement 7 ou de précipitation du carbone où la bande se déplace horizontalement et effectue un nombre réduit de passages très longs, ce qui limite les cylindres de renvoi à un nombre très restreint, éventuellement nul.
