Beschreibung
Zusammenfassung:	The invention relates to a method for heating at least one semi-finished metal products to be further laminated, by means of a heat exchanging device comprising a chamber containing solid particles, supporting means able to support semi-finished metal product and a gas injector, comprising the steps of: i. injecting a gas into said chamber so as to form a fluidized bed, ii. inserting at least one hot semi-finished metal product such that said at least one hot semi-finished metal product is able to transfer heat to said fluidized bed, iii. inserting said at least one semi-finished metal product to be further laminated such that said fluidized bed is able to transfer heat to said at least one semi-finished metal product to be further laminated, iv. taking out said at least one semi-finished metal product to be further laminated of said fluidized bed when the temperature of said at least one semi-finished metal product to be further laminated is less than 100°C below the temperature of said fluidized bed. L'invention concerne un procédé de chauffage d'au moins un demi-produit métallique à stratifier davantage, au moyen d'un dispositif d'échange de chaleur comprenant une chambre contenant des particules solides, des moyens de support aptes à supporter un demi-produit métallique et une soupape d'injection, comprenant les étapes consistant à : i. injecter un gaz dans ladite chambre de façon à former un lit fluidisé, ii. insérer au moins un demi-produit métallique chaud de sorte que ledit au moins un demi-produit métallique chaud est apte à transférer de la chaleur audit lit fluidisé, iii. insérer ledit au moins un demi-produit métallique à stratifier davantage de sorte que ledit lit fluidisé est apte à transférer de la chaleur audit au moins un demi-produit métallique à stratifier davantage, iv. retirer ledit au moins un demi-produit métallique à stratifier davantage dudit lit fluidisé lorsque la température dudit au moins un demi-produit métallique à stratifier davantage est inférieure à 100 °C au-dessous de la température dudit lit fluidisé.
