Abstract

La présente invention se rapporte à un dispositif de transfert pour four de chauffage. Selon l'invention, le dispositif de transfert comprend un tube à patin ayant un passage de refroidissement dans lequel de l'eau de refroidissement est stockée, une unité de bouton de patin accouplée au tube à patin pour supporter un objet à travailler, et une source de chaleur qui fournit de la chaleur à l'unité de bouton de patin. Selon la présente invention, étant donné que l'unité de bouton de patin qui est en contact avec l'objet à travailler ne tombe pas au-dessous d'une température prédéterminée, une variation de la température entre une partie de l'objet en contact avec l'unité de bouton de patin et une partie de l'objet qui n'est pas en contact avec l'unité de bouton de patin peut être réduite pour améliorer la qualité de l'objet.
