摘要:
The present invention relates to a device and a method for transversely moving tubular material inside a furnace, in which the tubes are able to roll in order to have a path per cycle that is 2.5 times as great as that obtained in the case of moving bars, and in which the tubes are pushed by a series of toothed bars that have an upward and downward movement plus a horizontal movement in vacuum. The device and a method for moving tubular material inside an furnace allows a greater rotation of the tubes over short cycle times, solves the problems of twisting of smaller-diameter tubes (tubing) in quench furnaces and meets the need to rotate the tubes when there is no forward movement, which may be necessary when cycle times are long or when unloading from the furnace is interrupted.

A supporting device (200) includes a support body (210) for supporting a substrate (330) and an auxiliary wing (220) for supporting the corner of the substrate (330), so that the substrate (330) is substantially horizontally disposed on the supporting device (200). Also disclosed is a substrate transportation equipment (300) including the supporting device (200) and a movable protruding member (344). The substrate transportation equipment (200) can prevent the movable protruding member (344) from hitting the edge of the substrate (330) when the movable protruding member (344) moves.
摘要:
The invention concerns a foundry reheating furnace including an enclosure provided with burners for reheating foundry products travelling from one end of the furnace to another, said enclosure comprising a downstream zone, relative to the direction of movement of foundry products within the tunnel, which zone is associated with the discharge of said products and sealed by a discharge door. According to the invention, the downstream discharge zone (34) is defined, on the upstream side, by at least one geometric obstacle (50) defining a discharge lock, said at least one geometric obstacle being arranged to enable separation of the flows and heat transfers, so that the foundry products in the discharge lock are thermally homogenised.
摘要:
In Erwärmungsöfen wird der Stahl als Wärmgut (6) auf Walztemperatur erhitzt. Dabei wird er in der Regel auf geradeaus durchlaufenden, wassergekühlten Tragrohren verfahren, die im Bereich der Berührungsstellen das Erreichen der gewünschten Temperatur hemmen. Ein einmaliges seitliches Versetzen der Tragrohre oder ähnliche Maßnahmen konnten dieses Problem noch nicht lösen. Die Tragrohre (3) des vorliegenden Erwärmungsofens (1) weisen daher mehrfache seitliche Versetzungen (11, 12, 13) auf, die zwischen dem Eintritt (8) des Ofens (1) und dem Austritt (9) liegen oder beim Vorhandensein eines Festherdes (14) als Ausgleichszone bereits vor dieser im Ofenendbereich enden. Dabei ist jeder weiter stromab liegende Tragrohrabschnitt (L₂, L₃), der sich durch die Versetzung (11, 12, 13) ergibt, kürzer als der vorangegangene Abschnitt (L₁). Diese Anordnung ist besonders bei Stoßöfen oder Hubbalkenöfen vorteilhaft.
摘要:
Hubbalkenofen (1) mit einem Herd aus jeweils mit ihrer Längsachse zur Vorschubrichtung angerordneten Fest- und Hubbalken (4; 8). Sowohl die Hubbalken (8) als auch die Festbalken (4) sind in Vorschubrichtung in Abschnitte (16 bis 18; 13 bis 15) unterteilt, und jeder Abschnitt ist gegenüber dem benachbarten Abschnitt versetzt angeordnet. Dadurch kommt das Glühgut (22) in den Transportpausen jeweils an verschiedenen Stellen mit den gekühlten Festbalken in Berührung und ergibt sich ein Temperaturausgleich an den Berührungsstellen.

The invention relates to a roller hearth furnace (1) for heating and/or temperature equilibration of continuous cast products (2), comprising a first series of rollers (13) running in the longitudinal direction (12) and a second parallel series of rollers (15) on the outlet side (14), wherein a buffer zone (16) with lifting elements (17) for the perpendicular transport of the continuous cast product (2) is arranged between the series of rollers (13, 15). Furthermore, alternative arrangements for a further process route (28) are provided.
