Patent

CA 2259693

The invention discloses a method for temper-hardening flat metal products, comprising the following steps: introducing a flat product (31) coming out of the furnace into a temper-hardening bay, depositing this flat product (31) on supporting elements forming a lower substantially horizontal supporting table (5), causing a sudden cooling of the flat product (31) in the deposited position, by spraying a temper-hardening liquid simultaneously on the whole of its upper surface and on the whole of its lower surface, removing the flat product (31) from the temper-hardening bay, and further, before the sudden cooling, transferring staying elements forming together a substantially horizontal staying table (9) to a horizontal staying plane located at a predetermined distance above the upper surface of the flat product (31) and, during the sudden cooling, optionally staying the flat product on the upper staying table (9), within the limits imposed by the said horizontal plane. The invention also discloses a device for implementing this method.

Procédé de trempe de produits métalliques plats, comprenant une introduction d'un produit plat (31) sortant d'un four dans un poste de trempe, un dépôt de ce produit plat (31) sur des éléments de support formant ensemble une table de support inférieure (5) sensiblement horizontale, un refroidissement brusque du produit plat (31) en position de dépôt, par aspersion d'un liquide de trempe simultanément sur toute sa surface supérieure et toute sa surface inférieure, une évacuation du produit plat (31) refroidi hors du poste de trempe, et en outre, avant le refroidissement brusque, un transfert d'éléments de retenue formant ensemble une table de retenue supérieure (9) sensiblement horizontale jusqu'en un plan horizontal de retenue situé à une distance prédéterminée au- dessus de la surface supérieure du produit plat (31) et, pendant le refroidissement brusque, une retenue éventuelle du produit plat par la table de retenue supérieure (9), dans des limites imposées par ledit plan horizontal de retenue, et dispositif pour la mise en oeuvre du procédé.
