Abstract
一种热轧设备应如此构造和运转，即可轧制出厚度小于1毫米的且由变形难易程度不同的材料构成的带材，其中在最后一架轧机的出口侧与所用材料无关地不应超过15m/s的带材速度，而且该轧制带材应具有奥氏体组织。为此建议：对易变形材料来说，使用约50毫米厚的薄板坯；七机架轧机的第一架抬起或或只进行一道光轧，板坯在第一机架前后进行除鳞；并且第二至第七机架将厚度减小到不到1毫米。
Description
本发明涉及用于由变形难易程度不同的材料构成的且按宽度划分规格的品种的热轧薄带的热轧设备以及这样的热轧设备的运转方法。
已经公开了七机架热带材轧机，该轧机被接在连铸机和均热炉之后。可以用这样的热轧设备轧制变形难易程度不同的1.5-1.2毫米厚的热轧带材，其中，在最后一架轧机出口侧的带材仍具有奥氏体组织。在最后一架轧机出口侧的带材速度也可以用简单构成的并跟在热轧设备后的成套设备如一剪切机和卷取装置来控制。
至少对易变形材料来说，无法用该轧机进一步减小轧制带材厚度，其起因有多方面，一方面，在热带材轧机的最后一架出口侧的带材平均温度应不低于奥氏体轧制所需的温度(约860℃)，另一方面，在热带材精轧机的最后一架出口侧的速度不应超过约12.5m/s，这是因为，热否则的话，热轧带材无法再通过简单的手段在输出辊道上导向移动并随后进行卷取。另外，为开始卷取而必须被加速到大于15m/s的圆周速度的卷取装置必须很复杂、成本高昂且很困难地进行调节。
如果易变形材料应在奥氏体区内被轧到小于1.2毫米且尤其是小于1毫米的厚度，则在这种已知设备里从最后一个机架中得到了超过15m/s的出口速度。若调定较慢的出口速度，则在最后一架里已经低于了奥氏体轧制所需的带材温度，即不再是奥氏体轧制了。
当轧制难变形材料时，也可以用七机架热带材轧机获得小于1.2毫米厚度，这是因为由于轧制功大，所以，即使在低速情况下，也在最后一架轧机后能找到奥氏体组织。但该热轧设备不适用于最终厚度小的易变形材料。
已经知道了，这样的七机架轧机低速工作并在通过卷取机获得张力后使整套设备加速。在加速阶段中轧制的带材常常是废品，因而这样的设备无效工作。
此外，尤其是该热轧设备的传动部件在高速时承受很高负载并因而摩损更快，结果，必须设置复杂的驱动组成部件、卷取机和剪切机以及精确得多的动调节机构，以保证所希望的带材质量。
本发明的任务是这样设计一种热轧设备以及使该热轧设备运行的方法，即在出口厚度小于1.2毫米且尤其小于1毫米的轧制过程之后，即使轧制的是易变形材料，仍存在这样的带材温度，即该温度保证了奥氏体轧制，而轧件的出口速度仍不超过15m/s，从而得到了易控制的工作过程，设备摩损减小并可以使简单构成的成套设备的成本保持较低。
为完成该任务而提出一台具有权利要求1所述特征的热轧设备。通过该热轧设备，可以顺利地将由变形难易程度不同的材料构成的热轧带轧到约1.2毫米厚。不过，通过用于变形难易程度不同的材料的本发明特征与合理成本的结合，也可以轧制出厚度小于1.2毫米且尤其是小于1毫米的轧制带材。
结合附图对本发明进行详细叙述。附图示出一台热轧设备，它为了变形难易程度不同的材料而可以被如此投入运转，即与所用材料无关地并且尽管因此而出现了不同条件，但对所有材料来说，在最后一架上出现了保证奥氏体轧制的终轧温度，并且获得了小于约15m/s的速度。
该热轧设备包括一个薄板坯连铸设备1，它的连铸坯导向装置是可以调节的，从而在薄板坯连铸设备1的出口处获得了约为45-70毫米的薄板坯厚度。连铸薄板坯可用一台剪切机2被切分开。在这里，可以出现这样的板坯段，即它们等于终轧带卷的长度或者是其多倍。定尺板坯段在一个均温的辊底式加热炉3中被保持在如1150℃的温度。接在辊底式加热炉3后面的是一台剪切机4，该剪切机只在出故障时才使用。
接在辊底式加热炉3后面的是一台喷水除鳞装置5，后面是一台具有轧辊尺寸F1-F7的七机架轧机7。在轧机7的出口侧设有一个冷却段8，在带材运行方向上，在该冷却段之后是一台飞剪9，这台飞剪在半连续或连续轧制时投入使用。该热轧设备的末端是两台卷取机10，它们在一替换方案中也可以被设计成旋转卷取机的形式。
在机架F1和机架F2之间设有一个机架间除鳞装置6。
根据材料的所需的最终厚度的不同，可以采用不同的轧制方法。
如果要轧制难变形的材料，那么如此来调节薄板坯连铸设备1，即根据所需的最终厚度和连铸机产量，采用厚度为45-70毫米并最好是55毫米的板坯。所有七个机架F1至F7都开动了。机架间除鳞装置6未被起动。在这种运行方式中，通过高轧制力和输入到难变形的待轧材料中的大量功，就可以在机架F7出口侧获得厚度小于1毫米的轧制带材，在此不超过约15m/s的速度，因而存在具有奥氏体组织的轧制带材。
如果要轧制最终厚度＞1毫米的易变形材料，则选择55-70毫米厚的薄板坯。所有机架F1-F7都被投入工作中，而机架间除鳞装置6不工作。
在轧制最终厚度小于1毫米的易变形材料时，薄板坯连铸设备必须被调到45-50毫米的薄板坯厚度。机架F1或是不工作的，或是被调整以进行一道压下量较小的光轧。这道光轧造成板坯表面更光整，从而在喷水除鳞装置5后形成一个更均匀的氧化层。因而，工作的机架间除鳞装置6可以更容易地去除新生氧化皮。也就是说，喷涂在板坯上的除鳞介质比机架F1未光轧调整时少。
通常，机架F2-F7要比在所有七架轧机都被起动的运行方式时略大一些地被压下。由于只使机架F2-F7运转，所以获得了更低的终轧速度。由于输入板坯厚度较小且机架F2-F7压下比较大，仍获得小于1毫米的终轧厚度，在这里，轧件具有在奥氏体组织区内的温度。
因此，利用现有的热轧设备，难变形材料和易变形材料都可以在奥氏体区内被一直轧制到不到1毫米的厚度，而在机架F7上的出口速度不超过15m/s。因而，整个过程可以简单设计，并且热轧设备的成套设备如剪切机和卷取机具有其简单而经济的构造。不需要增加成本。
