The invention relates to an apparatus for supporting material to be treated in continuously operated thermal treatment furnaces, wherein the support of the material is carried out by means of suport elements external to the furnace, and where the material is made to proceed at a high velocity, said apparatus comprising at least two elements for supporting the material and a member for supporting the support element, as well as means for cooling the support element. According to the invention, the support element (7) comprises at least one rotation support member (8), provided with a turnably installed tightening element (9), and at least one actuator arrangement (4) for making the support element (7) rotate essentially at an equal circumferential velocity as the proceeding direction of the material (2).
L'invention porte sur un appareil destiné supporter un matériau à traiter dans des fours de traitement thermique à fonctionnement continu. Le support du matériau est réalisé au moyen d'éléments de support extérieurs au four et est conçu de façon à être traité à haute vitesse. Cet appareil comprend au moins deux éléments destinés à supporter le matériau et un élément pour supporter l'élément de support, ainsi qu'un dispositif permettant de refroidir l'élément de support. Selon cette invention, l'élément (7) de support comprend au moins un élément (8) rotatif pourvu d'un élément (9) de serrage monté rotatif et au moins un dispositif (4) d'actionnement permettant de faire tourner l'élément (7) de support à une vitesse circonférentielle principalement égale à la vitesse de traitement du matériau (2).
