Abstract: A method for cutting a cast strand or intermediate strip using shears. In order to facilitate improved rolling of the section having significantly reduced thickness, the method according has the following steps: a) bringing part of the completely solidified cast strand or intermediate strip in the conveying direction (F) of the cast strand or intermediate strip in front of the shears; b) placing a first blade of the shears onto the one surface of the cast strand or intermediate strip and placing a second blade of the shears onto the other surface of the cast strand or intermediate strip and performing a cut by carrying out a relative movement of the two blades, wherein at least one of the blades is in a pushed-forward position; c) upset forging or upset forging with stamping a wedge-shaped contour on the end of the cast strand.

Abstract: A device (100) and a method for cooling a knife-bearing element (102.1, 102.2) of a cross-cutting shear (103), which is in particular installed in a hot rolling mill, are described. When the knife-bearing element (102.1, 102.2) is at standstill, at least one guard device (105) is positioned in a cooling position (K) between the knife-bearing element (102.1, 102.2) and a roll strip (101) running continually through the roller mill, such that a side of the knife-bearing element (102.1, 102.2) opposite the roll strip is shielded by the guard device (105).

Abstract: A shear, in particular a cross-cutting shear, for cutting flat material, including a upper blade support and a lower blade support, at least the upper blade support or the lower blade support being reciprocatingly displaceably guided and being displaceable by at least one adjustment device relative to the other respective blade support. The displaceable blade support is guided by the adjustment device and the adjustment device is designed so that it absorbs all the cutting forces and transversal forces.

Abstract: The invention relates to an apparatus for winding and unwinding rolled strip (WB) discharging from a mill train (WS), in which apparatus the rolled strip (WB) discharging from the mill train (WS) is introduced by a set of bending rolls (BR) into a winding chamber (WK) having a rotationally driven roller pair (RP) and is wound into a coil (WB), and the coil is then put onto a roller table (GR) and unwound from these rollers with the direction of rotation being reversed and the start of the strip is fed to a driver device (RT). The apparatus is improved by a supporting slide (TS) which can be pushed into the winding chamber (WK) and in whose side walls a pivoted lever (SH) is mounted, the free end of which carries a pressure roller (AR) which can be put onto the rolled strip coil and pushes the latter out of the winding chamber (WK) onto the adjoining roller table (GR).

Abstract: A method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product with the aid of flowable media which are sprayed onto the cast product by a cleaning device having at least one spraying apparatus that is disposed above the cast product and at least one spraying apparatus that is arranged below the cast product. According to the method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus.

Abstract: The invention relates to a drum shear arrangement (1) having two rotatably driven drums (3, 4) arranged on a stand (2) with their axes extending parallel to each other, and provided, respectively, with a knife (5, 6) on their profiles, wherein upon passing a metal sheet in a gap between the drums (3, 4), under at least partial rotation of the drums, the metal sheet is cuttable, and wherein inlet and/or outlet side of the stand is provided with at least one first roller group (10, 11) displaceable in a region of the stand (2) and in a region between the drums (3, 4).

Abstract: Disclosed is a method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product (3), such as a slab, thin slab, profiled element, or similar, with the aid of flowable media which are sprayed onto the cast product (3) by means of a cleaning device (5) comprising at least one spraying apparatus (8, 9) that is disposed above the cast product (3) and at least one spraying apparatus (8, 9) that is arranged below the cast product (3). According to said method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus (8, 9).

Abstract: The invention relates to a coil box, which is mounted between a roughing rolling train and a finishing rolling train, for metal pre-strips, in particular steel strips, which are hot wound to form coils and are protected against further cooling in the vicinity of a winding and/or unwinding station (6) by means of heat-shield devices (7) on the front faces (5a; 5b) of the coils. The aim of the invention is to universally configure said coil box. To achieve this, the heat-shield devices (7) are configured from lateral walls (8; 8b) that can be pivoted to rest against the front faces (5a; 5b) of the coils and a pair of opposing heat-shield devices (7) can be aligned in parallel to different coil widths (5c).

Abstract: The invention relates to a method for expanding the use of a coiling and uncoiling station (coilbox) located between the roughing train and the finishing train for rolled strip material in hot-rolling mills. The use of said coilbox is expanded by impinging the coil that is to be uncoiled with a pressing force (F) which acts in the direction of the roller table (4) and/or placing the coil in a depression of the roller table in order to process smaller coil weights in a spikeless coilbox, and/or by combining, in a chronological and weight-related manner, the active transfer and passive transfer of a coil from a first coiling station to a second coiling station in order to increase the throughput especially at average coil weights in a spikeless coilbox, and/or by supplying heat to the strip upstream or downstream of the spikeless coilbox and/or thermally insulating the strip or the coilbox in order to variably increase and homogenize the strip temperature.
