Description

热轧薄钢带的方法及其装置
                       技术领域
本发明涉及薄钢带的热轧。更具体地，本发明涉及由双辊钢带铸造机生产的薄钢带的联机热轧。在EP0450775、EP0947261和WO01/96047中对双辊钢带铸造机进行了说明。
                       背景技术
双辊钢带铸造的最近发展已经能够使所生产的钢带厚度为5mm左右或更薄。这种钢带通过随着钢带被铸造机生产而在联机热轧机中减薄而可以进一步减小厚度。已经发现当热轧钢带厚度为3mm左右或更小时，由于钢带材料在进入轧薄辊时翘曲而在钢带中产生明显的缺陷。这种缺陷可能较小，并呈现为钢带表面上可见到的曲线。然而，尤其是当轧制非常薄的钢带时，在轧制之前钢带的部分会变成折叠到一起，从而钢带的该部分被严重减薄并裂口，导致非常严重的缺陷。
热轧钢带的翘曲是由于在钢带宽度上钢带的减薄不同而造成，典型地是，钢带的中心部分比钢带边缘承受更大比例的减薄，这取决于进入的钢带外形。因此，钢带的中心部分将承受长度方向的压缩，而边缘将承受拉伸。这导致钢带的中心部分相对边缘向后滑移，从而，钢带的中心相对边缘被向后推，而产生了翘曲。然后，该翘曲被轧到钢带内部，而在表面上形成标记。在极端的情况下，钢带在翘曲处会完全折叠，并且折叠起来的材料被轧入内部，而形成严重缺陷。在钢带宽度上钢带减薄的不同可以局限到钢带宽度的一小部分上。这可以导致钢带的局部翘曲。翘曲程度与钢带宽度上减薄的差异大小以及受减薄不同而影响的钢带宽度的大小相关。
钢带的翘曲可通过应用钢带拉伸而得以减小。然而，由于很小的拉力或不能将拉力施加到从铸造模具中排出的钢带上，因此难于将较大的拉伸施加到从钢带铸造机中排出的钢带上。钢带在传送到联机滚轧机之前，可以悬挂成自由环形，并且处于低拉伸状态下。本发明提供了一种方法和装置，通过他们，可以基本上控制翘曲缺陷，而不需较大的钢带拉伸。
                       发明内容
根据本发明，提供了一种生产一类薄钢带的方法，其中该钢带是在双辊钢带铸造机中被连续铸造成厚度小于或等于5mm而生产出来的，并且当该钢带由铸造机生产时通过经由轧制机的一对工作辊之间的辊隙供给并在工作辊之间施加钢带挤压力而在联机热轧机中进行厚度减薄，其中，为了减少在热轧过程中由于在钢带的宽度上钢带减薄的差异导致的钢带中心部分相对边缘向后滑移而引起的钢带缺陷，在工作辊之前将离开铸造机的钢带围绕一导引辊运行，导引辊使钢带在进入工作辊之间的辊隙中之前缠绕到工作辊之一上。
优选地是，钢带钢带通过至少10°的包角缠绕在所述一个工作辊上，包角例如可以在20°到45°的范围内。
优选地是，工作辊一个在另一个之上地设置，在该情况下，所述导引辊可以定位成将钢带从通向辊隙的水平路径向上导引，并然后在进入辊隙之前围绕上工作辊向下导引。
本发明也提供了一种用于生产此类薄钢带的装置，包括：双辊钢带铸造机，其可将钢带连续铸造成厚度小于或等于5mm；与该铸造机联机安装的热轧机，从而当该钢带由该铸造机生产时通过热轧该钢带可对该钢带进行厚度减薄，所述轧制机包括一对在其间确定辊隙以接收钢带的工作辊和将挤压力施加到工作辊之间的装置，其中将钢带导引到工作辊之间的辊隙的导引辊，其使得钢带在进入辊隙之前缠绕在工作辊之一上。
优选地是，工作辊一个在另一个之上地设置，而导引辊从较低位置和升高的工作位置移动，在较低位置，钢带可以在导引辊之上、在水平路径中被传送到工作辊之间的辊隙，而在升高的工作位置，导引辊将钢带升高到所述水平路径之上，以使钢带在辊隙之前缠绕到上工作辊上。
                       附图说明
为了更全面地解释本发明，将参照附图详细描述本发明的特定实施例，图中：
图1示出了用于轧制薄钢带的钢带碾压设备的一部分；以及
图2是图1中线2-2上的横截面；
图3示意性地示出了合并在该装置中的带引导的工作原理。
                       具体实施方式
附图示出轧制机设备，其用于接收由双辊铸造机生产的薄钢带11并用于在该钢带由铸造机生产时通过对其进行联机轧制使其厚度减薄。
在所示的轧制机设备中，薄钢带11穿过包括一对夹送辊13的夹送辊机架12，钢带夹紧力通过一对液压缸单元14施加到夹送辊13上，夹送辊机架的每一侧上设置一个液压缸单元14。
在穿过夹送辊机架12后，钢带11支承在由一系列辊15形成的工作台上，钢带通过该工作台传送到轧制机16，轧制机包括一对一个设置在另一个之上的工作辊17和一对上和下承压辊18。钢带减薄的力通过液压缸单元(未示出)施加到工作辊17之间，液压缸单元设置在轧制机的两侧并通过上承压辊18起作用。在夹送辊机架12和轧制机机架16之间，钢带被保持在密封的机壳19中。
根据本发明，该设备包括导引辊21，其刚好位于轧制机16之前，并安装到一对摇杆构件22上，摇杆构件22可以通过液压缸30的致动而围绕水平枢轴23枢转，液压缸30通过机械连杆机构31作用在摇杆构件上，从而使引导辊能够升高并降低。引导辊21具有较低的非工作位置(在图1中由虚线标示)，在该位置处，钢带可以水平地直接传送到轧制机的工作辊17之间的辊隙26中。引导辊21然后可以通过液压缸30的工作而升高，以将钢带抬离其直线水平路径，从而，钢带围绕引导辊传送，并在辊隙26之前缠绕在上工作辊17上。
引导辊枢轴23被支承在机壳19侧壁中的承载支架中，且该轴的一端穿过旋转密封，以与连杆机构31相连，从而液压缸30工作时，轴可以由连杆机构31转动。液压缸30的有效形成可以通过操纵电螺旋起重器来设定挡块33而调节，以便调节处于升高位置的引导辊21的高度。
为了在引导辊21升高时，保持钢带下落到工作台辊15上，刚好在一个工作台辊15之后，上轧制线辊27向下与钢带形成接合。辊27安装到摇臂34上，摇臂34从连接到一端的枢轴35延伸到位于机壳19外侧的杠杆臂36上，并可以由液压缸37致动，以转动轴35，由此升高和降低上轧制线辊27。
已经发现引导辊在实际中高效地减少了翘曲缺陷，即使在非常薄的钢带中。由于钢带围绕上工作辊缠绕，工作辊制成钢带并阻止钢带的翘曲。钢带围绕上工作辊的曲率也可以增大对钢带在辊隙之前的关键区域内的横向翘曲的抵抗能力，这是由于钢带在该区域内的有效的弯曲形状所导致的。
已经发现为了更有效的抵制翘曲，钢带应该通过至少10°的包角缠绕上工作辊，而优选地在20°到45°的范围内。在典型的设备中，工作辊直径可以在400mm到700mm范围内，而抗卷曲辊可以定位成将钢带升高到通过工作辊之间的辊隙的水平面之上的150mm到250mm之间。
