    Abstract: A primary object of this invention is to provide a continuous casting method by which a slab of excellent internal quality can be obtained even if the casting speed is changed. In this invention, upon continuous casting with two pairs of the reduction rolls arranged along a casting direction and support rolls arranged between the reduction rolls, when a casting speed is reduced compared to a state where combination of reduction with reduction rolls at a first stage on an unsolidified portion of the slab and reduction with reduction rolls at a second stage on a solidified portion thereof is employed, the combination is switched to combination of reduction with the reduction rolls at the first stage on a portion of the slab at an end of solidification and the reduction with the reduction rolls at the second stage on the solidified portion thereof.

    Abstract: A method for rolling thin and/or thick slabs made of steel materials into hot-rolled strip, which were previously cast as thin or thick slabs in a continuous casting machine, heated to rolling temperature in a pusher furnace or in a walking-beam furnace, and rolled in a common rolling train, then cooled and wound into coils. The method is carried out in a continuous manner at maximum capacity of the roughing train according to the quality standard of the hot-rolled strip while roller wear is reduced due to the fact that the roughing train is formed inline by roughing stands and finishing stands into which thin slab sections or thick slab sections are introduced at a suitable point of the roughing train according to the thickness thereof.

    Abstract: In a method for vertical continuous casting of a steel band, a strand (11) of a parallelogram-like cross section is cast at first in a revolving chill-mold (2) and is thereafter transferred from said initial cross section with completely solidified longitudinal edges (10) and liquid core into a band (1) with plane-parallel cross section, this occurring in such a way that an already solidified shell (9) of the strand (11) which becomes increasingly thicker by cooling is increasingly compressed in the casting direction in a forming device (4) without upsetting deformation of the completely solidified longitudinal edges (10). In order to provide advantageous conditions it is proposed that after the compression into a band (1) the strand (11) with a still liquid core (16) is guided during the complete solidification of the core merely in a forming gap with a constant width corresponding to the thickness of the completely solidified longitudinal edges (10) and is calibrated in this process.

    Abstract: A method and device for producing a strand of metal by means of a continuous-casting installation which has at least one cooling device for cooling the strand, the cooling device being assigned at least one reduction stand for reducing the thickness of the strand, the strand, during the thickness reduction, having a solidified skin and a liquid core. The cooling is set, by means of a temperature and solidification model, in such a manner that the solidification boundary between the solidified skin and the liquid core when the strand enters the reduction stand corresponds to a predetermined set solidification boundary between the solidified skin and the liquid core.

    Abstract: A continuously cast steel strip which consists of a solidified casting shell and a liquid core is reduced in thickness in a roll deformation and is then rolled. In order to avoid undesired fluctuations in thickness, to improve the structure and to simplify the roll deformation unit, a steel strip billet of 40-80 mm thickness is cast, roll deformed to 15-40 mm thickness having a 2-15 mm residual liquid core in a maximum of three steps. The roll deformed billet is then guided to complete solidification.

    Abstract: In a process for the continuous casting of steel, molten steel is vertically cast in mold means to form a strand having an elongate shape in cross-section and is caused to solidify as it flows through the mold means. To permit a thin strand to be efficiently produced, the strand is first cooled while a constant cross-section is maintained, that cooling is continued until a strong shell which has entirely been solidified at least in the narrow side walls has been formed, and the cooling and solidification of the strand are subsequently continued while the strand is progressively deformed and compacted to form a flat preliminary strip.
