Abstract
(EN) A multi-station vacuum annealing furnace for processing titanium pipes, which belongs to the technical field of vacuum annealing furnaces. The multi-station vacuum annealing furnace for processing titanium pipes comprises a bottom plate; support legs are uniformly welded to the peripheral edges of the bottom of the bottom plate, a support frame is fixedly connected to the left side of the upper surface of the top of the bottom plate, a storage compartment is in interference fit with the center of the upper surface of the top of the support frame; a locking mechanism is welded to the left side of the upper surface of the top of the storage compartment, a sealing door is fixedly connected to one side of the locking mechanism, the right side of the sealing door extends to an inner position of a storage frame, a pull rod is plugged into the bottom of the left side of the sealing door, and a cooling mechanism is in communication with the lower surface of the bottom of the storage compartment. The annealing furnace is connected to a heating tube by means of a hydraulic pump, then temperature raising and heating is performed on the annealing furnace by means of a heating box, and the cooling mechanism is installed to cool the annealed titanium pipes, allowing for high cooling speed; in addition, the storage compartment is sealed by means of the locking mechanism and the sealing door, improving the processing quality.
(FR) Four de recuit sous vide multi-station destiné au traitement de tuyaux en titane, appartenant au domaine technique des fours de recuit sous vide. Le four de recuit sous vide multi-station, destiné au traitement de tuyaux en titane, comprend une plaque inférieure ; des pieds de soutien sont soudés de manière uniforme aux bords périphériques de la partie inférieure de la plaque inférieure ; un cadre de soutien est relié à demeure au côté gauche de la surface supérieure de la partie supérieure de la plaque inférieure ; un compartiment de stockage est en ajustement serré avec le centre de la surface supérieure de la partie supérieure du cadre de soutien ; un mécanisme de verrouillage est soudé au côté gauche de la surface supérieure de la partie supérieure du compartiment de stockage ; une porte d'étanchéité est reliée à demeure à un côté du mécanisme de verrouillage ; le côté droit de la porte d'étanchéité s'étend jusqu'à une position interne d'un cadre de stockage ; une tige de traction est branchée dans la partie inférieure du côté gauche de la porte d'étanchéité ; et un mécanisme de refroidissement est en communication avec la surface inférieure de la partie inférieure du compartiment de stockage. Le four de recuit est relié à un tube de chauffage au moyen d'une pompe hydraulique, puis une augmentation de la température et un chauffage sont effectués sur le four de recuit au moyen d'une boîte de chauffage, et le mécanisme de refroidissement est installé pour refroidir les tuyaux en titane recuits, permettant une haute vitesse de refroidissement ; de plus, le compartiment de stockage est rendu étanche au moyen du mécanisme de verrouillage et de la porte d'étanchéité, ce qui améliore la qualité du traitement.
