    • The invention pertains to a method for manufacturing a metal strip (1) by means of continuous casting and rolling, wherein a thin slab (3) is initially cast in a casting machine (2) and this thin slab is subsequently rolled in at least one rolling train (4, 5) by utilizing the primary heat of the casting process, wherein a continuous manufacture of the metal strip (1) (continuous rolling) can be realized in a first operating mode by directly coupling the casting machine (2) to the at least one rolling train (4, 5), and wherein a discontinuous manufacture of the metal strip (1) (batch rolling) can be realized in a second operating mode by decoupling the casting machine (2) from the at least one rolling train (4, 5). In order to increase the flexibility of the system, the invention proposes that cast slabs (3) or preliminary strips (3′) are removed from the main transport line (6) downstream of the casting machine (2) referred to the strip transport direction (F) in the discontinuous manufacture of the metal strip (1), stored and subsequently transported back into the main transport line (6), wherein the removed slabs (3) or preliminary strips (3′) are heated to a desired temperature or maintained at a desired temperature prior to the transport back into the main transport line (6). The invention furthermore pertains to a device for manufacturing a metal strip (1) by means of continuous casting and rolling.
    • 本发明涉及通过连续铸造和轧制制造金属带(1)的方法,其中薄板坯(3)最初在铸造机(2)中铸造,并且该薄板坯随后在至少一个 通过利用铸造工艺的一次热量,可以在第一操作模式中实现金属带(1)的连续制造(连续轧制),直接将铸造机(2)连接到 所述至少一个轧制系(4,5),并且其中通过使所述铸造机(2)与所述至少一个轧制(2)脱模,可以在第二操作模式中实现所述金属带(1)(批轧)的不连续制造 火车(4,5)。 为了增加系统的灵活性,本发明提出,铸造板坯(3)或初步条带(3')从铸造机器(2)下游的主输送线(6)被移除 (F)在金属带(1)的不连续制造中,储存并随后被运送回主输送线(6),其中将移除的板坯(3)或初步条带(3')加热到所需温度或 在运送回主输送线(6)之前保持在所需温度。 本发明还涉及通过连续铸造和轧制制造金属带(1)的装置。

    • Energy is recovered from steel products produced in a steel mill where the products are transported into a storage area by first extracting heat from the steel products prior to or after transport into the storage area by heat exchangers for a predetermined period in which residual heat of the steel products is transferred by the heat exchangers into a heat-transfer medium to heat same. The heated transfer medium is then transferred via heat-transfer transport lines for power generation or for direct use of the process heat in other heat consumers. This transport of the heat-transfer medium from the heat exchangers to the power-generating plant in the heat-transfer transport lines is carried out only at pump feed pressure or using as a heat-transfer medium liquid mineral or synthetic thermal oil or a salt melt so as not to build up a steam pressure above 2 bar.
