摘要： The invention relates to a strand guiding device and a method for guiding a metal strip, in particular a metal strip that has not yet solidified right through, in a continuous casting installation. Known strand guiding devices comprise a segment frame and at least one pair of opposing guiding rollers, between which the metal strip is guided. At least one of the guiding rollers takes the form of at least two part-rollers 122, 124 arranged next to each other. The part-rollers are mounted on the segment frame 110 by means of two outer bearings 132, 134 and at least one common intermediate bearing 133. To provide at least partial compensation for the segment frame 110 springing up or bending, caused indirectly by the ferrostatic pressure in the interior of the metal strip that has not yet solidified right through and occurring in particular in the region of the intermediate bearing 133 during the transport of the metal strip between the guiding rollers 120, three different means are proposed according to the invention, means which can also be used in combination with one another. These means are a bowing of the intermediately mounted guiding roller and/or a more yielding form of the outer bearings 132, 134 in comparison with the intermediate bearing 133 and/or a greater distance A1 between the segment frame 110 and the centre axis M of the part-rollers 122, 124 in the case of the intermediate bearing 133 in comparison with the outer bearings 132, 134.

摘要： The invention relates to a method for hot dip galvanizing hot rolled steel strip and to a hot rolled strip galvanizing installation. In a first method step, the strip (50) to be galvanized is introduced into a pickling station (10) inside of which the layer of scale as well as reaction products are removed from the surface of the strip. In a subsequent working step, the strip (50) is introduced into a rinsing station (20) in which residual pickle and pickle products are removed from the surface of the strip. Afterwards, the strip (50) is introduced into a drying station (30) and dried therein. From there, the strip (50) is introduced, in another method step, into a furnace (40) in which it is heated, under a protective gas atmosphere, up to a galvanizing temperature. In a final method step, the strip is guided through a galvanizing bath in which it is coated with a hot dip galvanizing layer. This method is improved in such a way that the strip (50) is heated in the furnace (40) to a temperature that does not exceed the bath dipping temperature in the zinc bath by more than 50 °K.

摘要： For various reasons, in the prior art it is considered difficult or impossible to produce steels with high manganese (Mn), aluminium (AI) and silicon (Si) contents and with TWIP (Twinning Induced Plasticity) properties by continuous casting. The reasons cited include low strength of the strand shell during solidification on account of extensive micro-segregation of Mn, high strength at lower temperatures, reactions of the aluminium in the steel with the casting powder, macro-segregations, depletion of the alloying elements in the surface region and oxidation of the grain boundaries during the reheating of slabs in the pusher furnace. Therefore, the invention proposes that, by successive process steps, lightweight structural steel with a predetermined chemical composition of up to 27% Mn, 1 to 6% AI, 1 to 6% Si,
