Abstract

一种轧机设备的运行方法,此轧机设备包括一架或多架立式粗轧机和一台通过连接辊道和一台横向送钢装置紧接在此粗轧机后的紧凑式精轧机组,在后续粗制钢坯进入此紧凑式精轧机组之前,从连铸机中输出的粗制钢坯在预定时间周期内且在没有中间储存的情况下被直接供给此轧机设备,并相继精轧成型材,接着把成品型材送入位于轧制线旁边的冷床。而当型材精轧时间长于由连铸机确定的时间周期时,把已从紧凑式精轧机组出来的轧件的第一纵切段从此轧件中切分出来并将其送往冷床。

Description

轧机设备的运行方法
本发明涉及一种轧机设备运行方法，此轧机设备包括一架或多架立式粗轧机，一相对此粗轧机横向错开设置的紧凑式精轧机组通过连接辊道和一台横向送钢设备紧接在此粗轧机后，此紧凑式精轧机组包括第一架万能轧机和第二架万能轧机或两辊轧机以及一设置在这两架万能轧机之间的立式中间轧机，其中，在后续粗制钢坯进入此紧凑式精轧机组之前或在进入此精轧机组时，从连铸机中出来的粗制钢坯在预定时间周期内且在没有中间储存的情况下被直接供给此轧机设备，在紧凑式精轧机组中将此粗制钢坯相继精轧成型材，接着将其送入位于轧制线旁边的冷床。
在此公开的方法中，设置在紧凑式精轧机组后面的冷床的传送宽度等于成品轧件的长度。当在轧件精轧段内为此轧机设备提供的粗制坯加工时间等于(或短于)连铸机生产粗制钢坯所需时间时，这种设置可以在连铸设备的时间周期内连续运转此轧机设备。
由于待轧精轧件的截面有所缩小及精轧件的单位长度重量相应有所减轻时，轧机生产的时间效率也降低了。对一种确定的型材尺寸来说，不再依据连铸机在时间周期内的生产量来计算轧机生产效率；只得对由连铸机生产的粗制钢坯采取成本昂贵的中间储存。
本发明的任务是改进轧机运行方法，小截面型材也可以在连铸机的时间周期内实现轧制。
上述任务是这样解决的，即在型材轧制中，当型材精轧时间长于由连铸机确定的时间周期时，把从紧凑式精轧机组出来轧件的第一纵切段从此轧件中切分出来并将其送往冷床。本发明还规定：纵切出的第一型材段最好具有长度为成品轧件总长一半的长度。第一型材段的纵切分是在轧制线上于冷床前进行的，纵切出的型材段从轧制线上被移入冷床。另一种可能是：第一型材段的纵切是在轧制线上在冷床(KB)后进行的，其中首先将第二型材段送入冷床，接着在轧制线上使第一段型材返回冷床前并将其送入冷床。
本发明的方法是在利用直到后续粗制钢坯进入紧凑式精轧机组前的空闲时间和在利用头两个距离较短的可逆道次的情况下得以实施的。当轧件在辊道上处于静止状态时，可进行轧件的切分，例如可采用简单的切割装置如锯或起割炬作用的飞剪或飞锯。
以下结合附图所示的实施例来描述本发明。其中：
图1是轧机设备的俯视示意图；
图2是轧机设备的另一种实施方式的俯视示意图。
如图1所示的实施方式中，此轧机设备包括：输入辊道R1；由万能轧机UG1、UG2和设置在这两个万能轧机之间的中间轧机ZG构成的紧凑式精轧机组；设置在此精轧机组后的输出辊道R2；设置在输出辊道R2和轧制线WL旁边的冷床KB；位于冷床KB前的切割装置TR。
如此运行此轧机设备，离开紧凑式精轧机组的第一成品轧件段PSTI在输出辊道R2上被送到冷床前并被停住。然后借助切割装置TR纵切出位于冷床KB前的第一段型材PSTI’并将其送入冷床。随后，尚处于输出辊道R2上的第二段型材PSTI”被移到冷床KB前并也被送入冷床。在此期间内，由后续粗制钢坯(未示出)经过短距离的头几道可逆道次轧制成的、由虚线表示的下一轧件段PSTII被移到输出辊道R2上，在精轧后相应地将此段轧件切断，由此产生的两段型材被送入冷床。
如图2所示的轧机设备的布置结构基本与与图1所示的布置结构相同，其改进在于：冷床KB以约等于一被切分轧件的纵切段长度的较短距离与紧凑式精轧机组间隔设置，沿轧制线WL方向看，切割装置TR位于冷床后。其中，从紧凑式精轧机组输出且位于输出辊道R2上的轧件PSTI在冷床KB前方，切割装置TR在输出辊道R2上静止切断此轧件，与图1所示实施方式不同的是(沿传送方向看)，随后将在后的型材段PSTI”送入冷床KB。接着在输出辊道R2上将第二段型材PSTI’沿与轧制方向相反的方向返回冷床KB前并将其送入冷床KB。按图1所示方式运行下一段轧件PSTII，但作了以下规定：首先将在后的型材段PSTI”送入冷床KB，然后将在先的型材段PSTI’返回冷床KB前并将其送入冷床KB。
