    Abstract: A cross-rolling mill for rolling a block over a mandrel forms a hollow block. It includes a plurality of working rollers, each of which exerts a substantially radially aligned rolling force onto the block. The working rollers are supported in a roll stand, and the gap between the working rollers and preferably also the alignment of the rolling axis of at least one of the working rollers relative to the block can be modified. Hydraulic actuators, preferably hydraulic capsules, are provided in order to modify the rolling gap and preferably also the alignment of the rolling axis of at least one of the working rollers relative to the block.

    Abstract: A device is disclosed for coupling a coolant supply and/or coolant drainage to a roll, especially in a continuous casting installation, wherein the roll includes a journal, which is mounted rotatably in a bearing block, and a lateral recess, extending in the axial direction, and at least one roll cooling channel, through which a coolant can pass. The device includes at least one coolant channel, which can be brought into fluidic connection with the roll cooling channel on the journal side; and a sealing unit for sealing the fluidic connection between the coolant channel and the roll cooling channel, including an inner module and an outer module. The inner module includes a hollow cylindrical element, which can be inserted into the lateral recess of the journal, and which, when viewed in the axial direction, has no flange on the outer side of the journal.

    Abstract: A heat treatment device for a thermal treatment of a workpiece is provided with a housing that houses a chamber for accommodating the workpiece for the thermal treatment. A first roller supports the workpiece and moves the workpiece in a moving direction. A first brush seal is provided, wherein the first roller and the first brush seal are arranged relative to each other such that a first side of the workpiece contacts the first roller and a second side of the workpiece that is opposed to the first side contacts the first brush seal such that the first roller and the first brush seal then seal at least a first section of the chamber from a second section of the chamber.

    Abstract: A method for monitoring the condition of a hydraulic system of a metal forming plant is presented. The hydraulic system is coupled to or provided with a pump drivable by a drive motor for providing a working fluid and with a heat exchanger. With the presented method, the following steps are initiated or carried out by a condition-monitoring device during the operation of the hydraulic system: Determining a current cooling power of the heat exchanger; determining a current conveying power of the pump; and determining a current maintenance urgency and/or a current ageing condition of the hydraulic system on the basis of the determined current cooling power of the heat exchanger. Furthermore, a condition-monitoring device designed to carry out the presented method is presented.

    Abstract: The invention relates to a method for producing a metallic strip or sheet (1), in which the strip or sheet (1) is rolled in a multi-stand rolling mill (11) and is discharged downstream of the last roll stand (14) of the rolling mill (11) in the conveying direction (F), wherein the strip or sheet (1) is cooled in the multi-stand rolling mill (11) and/or downstream of the rolling mill (11) as viewed in conveying direction (F), wherein a temperature of the strip or sheet (1) is measured upstream of the last roll stand (14) of the rolling mill (11) as viewed in conveying direction (F). Based on this measured temperature, a temperature for the strip or sheet (1) at the exit (A) of the last roll stand (14) of the rolling mill (11), is then determined purely by calculation with the aid of a temperature calculation model, with which temperature further processes of the manufacturing method can be controlled or regulated after a comparison with a predetermined reference value.

    Abstract: An apparatus for measuring a thread includes a holder for detachably holding a tube having a thread formed at an end of the tube. A first optical measuring section having an optical sensor is attached to a manipulator in order to move the measuring section relative to the tube. The optical measuring section is adjustably tiltable about a first adjusting axis relative to a thread axis of the thread. A second optical measuring section having a second optical sensor is arranged at the manipulator, wherein the optical measuring sections collectively form a measuring channel to provide simultaneous measurement of opposite sides of the thread of the tube.
