Abstract: A smelting unit for steel production with a tap weight of between 60 t and 350 t and a method for operating the same are disclosed. By a top lance that moves during operation of the smelting unit and the coordinated injection of process gases by sidewall injectors and the top lance, the undulations in the surface of the molten bath are reduced. As a result, fewer drops detach from the surface of the molten bath and soiling of the upper receptacle and the exhaust manifold is significantly reduced.

Abstract: A metal strip is guided on transportation rollers through a strip treatment installation. The installation includes successive strip movement control devices along a transportation direction. The strip movement control devices detect and adjust the position of the strip transverse to the transportation direction. A method for operating the installation includes: detecting the position of the strip transverse to the transportation direction by sensors of upstream strip movement control devices; identifying properties that influence the position of the strip transverse to the transportation direction of the strip by the sensors; assigning the identified properties of the strip to corresponding points or segments of the strip; and proactively adjusting the position of the strip transverse to the transportation direction at downstream strip movement control devices based on the properties for the corresponding points or segments of the strip identified by the upstream strip movement control devices.

Abstract: The invention relates to a roll stand (1) for rolling a metallic product and having two work rolls supported in the roll stand by respective work roll chocks (2), wherein axial displacement means (3) is provided with which the work rolls can be displaced in direction of their longitudinal axes, wherein at least one work roll locking means (4) is provided with which the work roll chocks (2) can be locked and unlocked in the roll stand (3), wherein rotation prevention means (6) is provided with which the axial displacement means (3) can be prevented from rotation about longitudinal axes of the work roll, and wherein bending means is provided which includes a bending block (5) and with which a bending torque can be applied to the work rolls. In order to achieve a simpler design of the assembly and improved lubrication possibilities for the component to be lubricated, according to the invention, the rotation prevention means (6) and the axial displacement means (3) are fixedly connected with the bending block (5).

Abstract: A device for determining orientation of an object, including a measurement body, which reflects electromagnetic radiation and can be brought into physical contact with a surface of the object to determine the orientation. The device includes: a measurement carriage movable along the object during the determination of the orientation and which has a sliding surface that can be brought into physical contact with the object; a retaining unit which retains the measurement body and is connected to the measurement carriage so as to be pivotable between a maximal position, in which the measurement body protrudes beyond the sliding surface on the object side, and a minimal position, in which the measurement body does not protrude beyond the sliding surface on the object side; and a restoring device that applies a force to the retaining unit toward the maximal position.

Abstract: A method and a device for guiding and centering a metallic rolling stock in a rolling mill having at least one assembly that is arranged in a rolling line and at least one rolling mill stand for shaping the rolling stock are disclosed. The method includes the use of lateral guide means, which exert a lateral force onto the moving rolling stock at different locations of the rolling line, wherein the method further includes the process of centering the inflow of the rolling stock ahead of a first assembly and/or ahead of a first rolling mill stand of the rolling mill using first lateral guide means and the process of aligning rolling stock downstream transversely to the rolling line using second lateral guide means, wherein the process of centering the inflow includes a funnel-shaped, flat guiding of the rolling stock and a point-shaped guiding of the rolling stock.
