    • During the continuous casting of preforms of large cross-section, considerable problems occur in the straightening region, because due to straightening, deformations are caused in the billet which has not yet solidified at the core. Therefore, in addition to the upper and lower straightening rollers additional lateral support rollers are provided, so that the billet is supported on all sides. For the purpose of space-saving incorporation in a multi-billet installation, the support rollers are mounted in swinging frames, which are moved by vertically raised cylinders. In order that the support rollers can be adapted to different billet dimensions, they are received within the fork-like swinging frames by vertically movable guide frames with roller supports inserted therein and able to be adjusted horizontally. Springs inserted in the swinging frames exert a continuous force in a vertical direction against the guide frames. Upon lowering of the upper straightening rollers, the pressure plates of the roller supporting beam bear against the guide frames, whereby an automatic adaptation to a new billet thickness is provided.
    • 在连续铸造大截面的预成型件期间,在矫直区域中出现相当大的问题,由于矫直,在芯部尚未固化的坯料中引起变形。 因此,除了上下矫正辊之外,还设置有另外的侧向支撑辊,使得坯料被支撑在所有侧面上。 为了节省空间并入多钢坯安装的目的,支撑辊安装在由垂直升高的气缸移动的摆动框架中。 为了使支撑辊能够适应于不同的坯料尺寸,它们通过垂直移动的引导框架容纳在叉形摆动框架内,其中辊支撑件插入其中并且能够被水平地调节。 插入摆动框架中的弹簧在垂直方向上对引导框架施加连续的力。 在上部矫正辊下降时,辊支撑梁的压板抵靠引导框架,由此提供了自动适应新的坯料厚度。

    • The invention provides method and apparatus for transporting tone signalling information through a GCME link in a GSM network supporting TFO and speech compression modes for the passage of signals through the link, respectively using TFO frames and TRAU-like In a data stream to the local entrance to the GCME link, a tone signal to be transported is detected. The detected tone signal is coded into bits of a TFO or TRAU-like frame for sending through the GCME link, including setting bits to mark the frame as a containing tone signalling information and setting bits to identify the detected tone signal, whereby the tone signalling information is transported in-band through the GCME link as a marked TFO or TRAU-like frame. At the remote exit from the GCME link, the marked frame is detected and the tone signal regenerated in dependence upon the bits of the marked frame.

    • A transport device for rapidly changing ladles for the continuous supply of metal melt to continuous casting plants by means of a reciprocating ladle bogie which is provided with means for receiving a sintle ladle. The bogie is moved between an operative position and an inoperative position, the bogie is positioned above a support from which an emptied casting ladle can be removed. In the operative position, the bogie is positioned above a casting station for supplying metal melt. The ladle bogie is open on the side nearest to the support and is rapidly driven back and forth between the inoperative and operative positions to provide a filled ladle from a crane and thereafter move an empty ladle to the support stand-by position for removal by the crane.

    • A method for rolling out a slab, preferably a slab produced by continuous casting, to form a billet having a square cross section, in which the width of the slab is reduced by repeated powerful edging passes, a temperature drop starting from the central region of the slab being provided during rolling, for example by spraying the edge regions of the slab with coolant, in order to give the edge regions greater deformation resistance and thus to prevent bulges at the edge regions. The bulge occurring in the central region of the slab is rolled away by guide rollers located at right-angles to the edging rolls. A rolling mill with suitable heating means is also provided.
