The invention relates to a belt discharger (1) for sealing a first space (2) with respect to a second space (3), the two spaces (2, 3) being passed by a belt (4), especially a metal belt, the spaces (2, 3) being sealed through provision of at least two rollers (5, 6) which adjoin the belt (4) with sealing on both sides. In order to achieve improved sealing action, the invention envisages that at least one roller (5, 6), in one of its axial end regions (7), has a sealing element (8) which is designed to laterally adjoin the belt edge (9) of the belt (4), with provision of adjustment means (10) with which the roller (5, 6) including sealing element (8) can be positioned in axial direction (a).

The invention relates to a strip sealing gate (1) for sealing a first chamber (2) with a first pressure level (p1) in relation to a second chamber (3) with a second pressure level (p2) that differs from the first, a strip (4), in particular a metal strip, passing through both chambers (2, 3). According to the invention, at least two rollers (5, 6) are provided for sealing the chambers (2, 3), said rollers resting in a sealing manner on either side of the strip (4). The aim of the invention is to improve the sealing action. To achieve this, at least some sections of the circumference of at least one of the rollers (5, 6) are covered with a flexible elastic material (7) and said roller or rollers (5, 6) have an inner core (8) that is covered with a jacket consisting of the flexible elastic material (7). A central region (9) of the inner core (8) has a cylindrical contour (10) and the edge regions (11, 12) of the core (8) are flared.

The invention relates to a device (100) for the connecting of strips to an endless strip with a clamping arrangement (110, 120) with a clamping device (110-r, 120-r) on the inlet side and a clamping device (110-l, 120-l) on the outlet side, a cutting arrangement (155) with an upper cutter (150) and a lower cutter (130) and with a joining arrangement, in which at least the clamping device (110-r, 120-r) on the inlet side and/or the clamping device (110-l, 120-l) on the outlet side is constructed as a premountable unit.
摘要:
To improve and further develop the heat treatment of the weld and the joining weld regions (6, 7) before and behind the actual welding by means of a laser, which is carried out during welding of steel sheets (2) to minimize the risk of crack formation or alteration of the microstructure in the region of the weld, it is proposed according to the invention that the heating of the region of the weld (6, 7) be carried out by means of a multiply stepped line inductor (4, 5) which can be set in a defined way and has zones of different power densities and is configured with a multiple division of its conductor loop lengths and/or with different plating of the conductor loops and/or with a plurality of spacing steps from the steel strip (2). Here, a steeper temperature rise occurs in the first heating stage than in the subsequent heating stage.

In a wire rod mill, the last rolling block or unit, either a finishing unit or a postfinishing rolling unit, with common drive is not used for traction control, but traction control upstream thereof is provided to regulate the cross section of the wire rod strand before entry into the last stage. The product is a wire rod strand of low cross sectional tolerance and high uniformity over the length of the rod.
