摘要:
A deflection for deflecting a strip in a reeling plant, in particular, of a metal strip from an initial channel to a final channel arranged above the initial channel and vice versa, wherein a drive acts with an upper drive roller on the upper side and with a lower drive roller on the lower side of the strip, can be improved when a temporarily pivotable into a strip, upper separating device is arranged downstream of the upper drive roller, and a temporarily pivotable into a strip, lower separating device is arranged downstream of the lower drive roller.

The invention relates to a device for deflecting sections of strip, in particular metal strip, in a coiling plant, from a beginning guide channel (1) to an end guide channel (2) and vice-versa, comprising a driver (3) with a pair of driver rollers (4, 4′) and control elements arranged downstream in strip conveyance direction, comprising a switch (5) that can be swiveled towards the beginning guide channel (1) or the end guide channel (2), and a guide table (6) which is swivelably supported under the switch (5) and positionable as a wiper against the lower driver roller (4′). The deflection of sections of strip is optimized in that the switch (5) is convexly shaped at its top and bottom sides and is flexibly arranged at the outlet end of an assigned strip transport roller-conveyor (7, 7′), such that it clears the beginning guide channel (1) when in a raised position and rests in the function of a wiper against the upper driver roller (4), and in that the guide table (6) is concavely shaped corresponding to the bottom of the switch (5). An actuating mechanism each, for example, a hydraulic unit (8, 8′), is assigned to both the switch (5) and the guide table (6).

摘要:
A method and device for driving the support rolls of a continuous casting machine for liquid metals, which support rolls form a strand guide for the continuously cast strand. The strand guide includes electrically driven individual support rolls and/or hydraulically adjustable support roll segments. An automatic load balance control system for the drives is used as the sum of the individual forces for casting speed, motor torque, motor speed, and standard correction factors and is provided with individual adjustment of torque and speed of each drive support roll motor. A total driving torque for all drives is determined from the normal force of the driven drive support rolls and proportionately transmitted to each support roll in such a way that a static base setting of the torque distribution is used as the basis for the specific load capacity of each drive support roll.

The invention relates to a coiling furnace (1), especially a coiling furnace (1) for Steckel rolling mills, wherein a hot-rolled strip (2) is coiled and uncoiled and optionally heated on a furnace drum (3) in the furnace interior (4) in a reversing manner. Said coiling furnace comprises guide tables (6) mounted on the mobile furnace door (5) of the coiling furnace (1) for inserting and/or guiding the heat-rolled strip (2), the furnace door (5) and the coiling furnace (1) being separate units. The furnace door (5) is arranged on a part of a roller rack (6) below the coiling furnace (1) and the furnace door (5) is subdivided into at least two elements (8, 9) that swing in relation to one another, both door elements (8, 9) being interconnected via a door bearing (10) and being configured to be pivoted. The invention is characterized in that the coiling furnace (1), in its interior (4), is configured with only one furnace roller (11) to allow complete insertion of the strip into the coiling furnace without the risk of the strip coming undone. For withdrawal of the strip a cover plate is placed on the door element and there is no need for a stripper.

The invention relates to a method and a device for driving support rollers (7c) on a continuous casting machine for molten metals, in particular, for molten steel materials, comprising a strip guide (7) of electrically-driven individual drive support rollers (7c) or hydraulically adjustable strip support roller segments (9) for the improvement of a load equilibration control (12), whereby a total drive moment for all drives (10), determined from the normal force of the driven drive support rollers (7c) is proportionately transmitted to each drive support roller (7c) and a static base setting for the torque distribution is used as the basis for the load capacity of each drive support roller (7c).
摘要:
A strand pulling-off method for a metal strand, particularly a steel strip, cast in a curved continuous casting plant, wherein the metal strand is initially vertically pulled from a casting mold, wherein a curved shape is then imparted on the metal strand in a curved entry driver driven with an entry torque, and wherein, after reaching a horizontal strand travel direction, the metal strand is finally straightened in a curved exit driver driven with an exit torque. An entry speed is assigned to the curved entry driver and an exit speed is assigned to the curved exit driver, the entry torque and the exit torque are determined, and the exit speed is adjusted in such a way that the entry torque as well as the exit torque have a positive value.
