Description

具有辊底式炉和回转运输机的CSP连铸设备
技术领域
本发明涉及一种连铸设备，其包括至少一个连铸部分、必要时至少一个还原单元、至少一个分割装置以及一个或者多个用于带材退火的装置以及一个后置的轧钢机列。
背景技术
所谓的CSP设备(紧凑式带钢生产设备)实现了热轧带材连续和明显更短时间的生产。在此将来自浇注罐的液态钢浇注到一个分配槽中，并借助于一个潜管从该分配槽浇注到一个结晶器中。该结晶器具有漏斗的形状，其在其高度的最后三分之一处才还原到两个平行的宽面。结晶器形状相应于冷却的钢的典型的收缩变化形状。该漏斗的优点还在于，钢会少应力地且无缺陷地固化。接着剪断机将以这种方式快速理想地固化的、具有大约50mm厚度的薄钢锭在其通过连续式炉加热到1150度的均匀轧制温度前进行分割。接着在精轧机列上进行轧制，精轧机列设计用于宽900至1600mm，并且厚度为0.8至6.53mm。六台或者七台高功率轧钢机座用于生产极薄的钢板，最后带材通过一个长的冷却段移动到卷取机，该卷取机将带材卷绕成钢卷。利用CSP设备生产具有有利的翼型特性(Profileigenschaft)、最佳表面质量以及很小尺寸公差的高品质热轧带材。
由文献EP 1 363 750B1公开了一种用于运行铸坯轧制设备的方法，该铸坯轧制设备包括至少一个钢锭生产线和至少一个轧钢机列以及至少一个钢锭输入装置，其在制造技术方面取决于钢锭生产线。在钢锭生产线生产暂停期间，钢锭输入装置根据物流以及/或者生产技术规定承担将钢锭输送到轧钢机列的任务，直到最大可实现的程度。所述其它钢锭生产线是厚钢锭生产线，其中铸坯轧制设备的钢锭输入装置从一个钢锭仓库中获得其钢锭，在钢锭仓库中按制造技术对预制钢锭进行缓冲。这些钢锭在一个自身的初轧机列中降低到能够卷绕的厚度。钢卷在铸造设备后面直接输送给轧钢机列。
发明内容
本发明的任务是在CSP设备、也就是在薄钢锭设备上提高生产率以及扩宽待运输的货物。
该任务如此解决，即提供一种连铸设备，其包括至少一个连铸部分、至少一个分割装置以及一个或者多个用于带材退火的装置以及一个后置的轧钢机列，为连铸设备设置至少一个平行延伸的轧制线，其具有将不同规格的钢锭加入连铸设备生产线的机构。通过由平行的轧制线加入不同规格的钢锭，实现了这种生产率的提高，使得实现了后接的轧制线最充分的利用，并且实现了钢材料不受限制的使用。
在本发明的改进方案中，为了将钢锭加入连铸生产线设置了回转运输机或者平行运输机。由此还可以将对为使用而来自平行轧制线的钢锭进行检查，并在必要时进行必要的后处理。
在按本发明的连铸设备的改进方案中，回转运输机或者平行运输机至少部分是平炉，尤其是辊底式炉。由此对于加入的钢锭实现了最佳的热传导以及最佳的温度平衡。
在连铸设备的另一种改进方案中，回转运输机具有与连铸设备的运输方向反向的运输方向，由此整个连铸设备就可以构造地极其紧凑。
在连铸设备的理想结构方案中，平行轧制线具有一个平炉和一个初轧机，该初轧机列具有水平和垂直顶锻机架(Stauchgeruest)或钢板轧制机架，以用于将加入的钢锭降低到CSP设备所要求的初始厚度，该初始厚度例如在40和70mm之间。借助于根据本发明的措施有利地实现了，可以在连铸设备上后接一个或者多个串联机架机列作为精轧机列，从而总体上产生一种生产率明显提高并且对于待运输的货物进行扩宽的CSP设备。
附图说明
根据示例性的实施例对本发明进行更详细地描述。
附图示出：
图1示出了一个具有双线路连铸设备的CSP设备，具有一个平行的轧制线，用于将钢锭借助于回转运输机加入连铸设备以及后接的精轧机列。
具体实施方式
在连铸设备1中，将液态钢从坩锅炉2浇注到未详细示出的中间容器中，并且借助于浸入式浇注管将液态钢从该中间容器浇注到漏斗结晶器中，其中浸入式浇注管同样没有示出。从漏斗结晶器将固化的钢借助于导向机架转向到一个水平辊道上，并在那里由分割装置分割成薄钢锭长度。薄钢锭到达辊底式炉3，以便其在那里被加热到大约1150度的均匀轧制温度，在该温度中进行平衡，并在必要时进行缓冲。将分割的具有大约50mm厚度的薄钢锭输入后接的精轧机列，在该精轧机列中，薄钢锭在多个机架5中降低到0.8至6.35mm。接着将轧制的带材输入一个具有分层冷却装置(Laminarkuehlung)的冷却段6，接着用卷取机7卷绕成所谓的钢卷。
为了提高所述CSP设备的生产率，并拓宽待输送的货物，除了连铸设备1还设置了平行的轧制线8，例如具有一个用于传统厚度的厚钢锭或者中等厚度的钢锭的炉以及一个双机架的初轧机列9或者钢板轧制机架，借助于它们可以将加入连铸设备1中的钢锭在CSP设备上降低到大约50mm的厚度。这些钢锭通过回转运输机或者平行运输机10或者10′从外部加入CSP线，并在那里设置的辊底式炉3中加热到必要的轧制温度，并在该温度中进行平衡，使得其接下去可以输入后接的精轧机列4，并在该精轧机列中能够以上述方法进行轧制、冷却以及卷绕成钢卷。
