Abstract: A roller for a roller hearth furnace, the roller including a water-cooled, rotatably mounted carrying axle on which a plurality of support rings are arranged at a spacing from one another. In the axial region between and next to the support rings, the carrying axle is provided with insulation composed of a fiber material and configured with protection of the outer circumference of the fiber material from the environment. In the case of insulation constructed from ring-shaped punched parts, the insulation arranged in the axial region between and next to the support rings is composed of circular or ring-shaped punched fiber parts. The protection is configured as ring-shaped insulating disks composed of a more resistant material than that of the punched fiber parts, and at least one punched fiber part is provided in each case between two insulating disks.

Abstract: A method for operating a system of the iron and steel industry for producing a metal product with participation of a severing or forming device. The actual value of an indicator be calculated over a length section of the metal product for the metal product to be produced. The indicator represents the resistance of the metal product to severing or forming processes. The calculated actual value pIst for the indicator p is then compared to a predefined threshold value. The severing or forming also only actually takes place when the actual value of the indicator of the metal product is less than the threshold value. If a comparison should show that the actual value of the indicator is greater than the threshold value, before the severing or forming of the metal product, a local processing of the metal product is performed in the corresponding length section.

Abstract: A roller hearth furnace, in particular a tunnel furnace of a thin-slabbing plant, including multiple cooled furnace rollers arranged in a mutually spaced manner in the transport direction in order to transport a strip or a slab have a number of support rings on a rotatably mounted axle and are formed with an insulation in the axial region between two adjacent support rings and adjacently to the respective outer support rings. The insulation is a highly insulating fiber material. Scale funnels are arranged below the furnace rollers. Scale barriers that extend transversely to the transport direction in the manner of the furnace rollers are provided in the free areas between each two successive furnace rollers in the transport direction.

Abstract: 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.

Abstract: 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.

Abstract: 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?).

Abstract: 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).

Abstract: 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.

Abstract: 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.
