    • The invention relates to a method for producing strips (1) of steel, preferably of silicon steel, in particular of grain-oriented silicon steel or of multiphase steel in which a slab (3) is initially cast in a casting machine (2), wherein this is then rolled in at least one roll train (4, 5) to form strip (1) and wherein before and/or after the at least one roll train (4, 5), the slab is heated in at least one furnace (6, 7). In order to improve the quality and the scope for producing grain-oriented silicon steel or multiphase steel, the invention provides that the slab (3) is heated to a pre-rolling temperature (T1) after the casting machine (2) and before a pre-roll train (4) in a first furnace (6), or the slab (3) enters into the pre-roll train (4) using the casting heat without the presence of the first furnace (6), the slab (3) is then rolled in the pre-roll train (4), the slab is then heated after the pre-roll train (4) in a second furnace (7) to a defined temperature (T2) that is higher than the pre-rolling temperature (T1), and then the slab (3) is rolled to the final strip thickness in a finish roll train (5).

    • A continuous-casting unit produces a longitudinally extending and traveling strand having a solid shell and a liquid core. A strand-guiding apparatus has a plurality of longitudinally spaced section frames and respective pairs of roller assemblies carried on the frames and transversely flanking and bearing transversely on the strand. Each pair forms a gap through which the strand passes, and each roller assembly is formed by two aligned subrollers. A respective center is provided bearing between the subrollers of each roller assembly and bracing inner ends of the respective subrollers transversely against the respective frame. Respective outer rollers at outer ends of the subrollers of each roller assembly brace the respective outer ends transversely against the respective frame. The subrollers are shaped or supported on the respective frame such that in an unloaded condition the gap is transversely narrower at the center bearing than at the outer bearing.

    • In hot strip plants, after casting, the residual heat of a partial quantity of the slabs has hitherto been used such that the slabs either are directly rolled or are placed warm or hot in the furnace. The remaining slabs normally cool after casting in a hall through which flows air and are stacked before their further transport. The same applies to the residual heat present in the coils after winding, which often cool in the coil-storage area in air. The cooling energy of the continuous-casting plant likewise escapes unused into the surroundings. In order to convert this unused solidification heat and residual heat into electric energy, it is proposed according to the invention that the slabs (10) are cast in a continuous-casting plant and the slabs (10) or coils are transported into the slab-storage area (12) or coil-storage area and during the casting in heat exchangers (31) and/or during the transport in heat exchangers (31) heat is extracted and/or there are deposited in part one on top of the other in specially prepared storage areas (30) provided with heat exchangers (31) for a short time or several hours, wherein in this transport period the cast billet or the slab (10) and/or in the storage period the residual heat of the slabs (10) or coils is transferred via heat conduction and thermal radiation and convection via the heat exchangers (31) into a heat-transfer medium such as, for example, thermal oil, and heats it, which then is discharged via heat-transfer transport lines (33) for power generation and/or direct use of the process heat by other heat consumers.
    • 在热轧带钢厂中,在铸造之后,迄今为止已经使用了部分板坯的剩余热量,使得板坯被直接轧制或者在炉子中放置成热或热。 剩余的板坯通常在大厅中冷却后通过空气流动并在其进一步运输之前被堆叠。 卷绕后的线圈中存在的残余热量也是如此,这在空气中的线圈存储区域中常常冷却。 连续铸造设备的冷却能量同样逃逸到周围环境中。 为了将未使用的固化热和余热转化为电能,根据本发明提出,将板坯(10)铸造在连续铸造设备中,并将板坯(10)或线圈输送到板坯 - 存储区域(12)或线圈存储区域,并且在热交换器(31)的铸造期间和/或在热交换器(31)中的输送期间,提取热量和/或在第一部分中沉积在另一个的顶部 特别制备的储存区域(30),其具有短时间或数小时的热交换器(31),其中在该运输期间,铸坯或板坯(10)和/或在储存期间,板坯的剩余热量( 10)或线圈通过热传导和热辐射以及通过热交换器(31)的对流传递到诸如热油的热传递​​介质中,并将其加热,然后通过热传输线排出 (33)用于发电和/或直接使用 其他热消耗者的过程热。
