Description

连续行进金属带的流体动力稳定装置
技术领域
本发明涉及减震流体动力装置，其允许在浸镀作业之后稳定通过干燥器的连续行进金属带。
本发明更特别地涉及连续运动钢带的热浸镀锌的领域。带的流体动力稳定在液态金属浴的出口并在干燥装置附近进行。
背景技术
已知称为“浸镀”的技术，它构成用于在物体表面沉积镀层的同时简单和有效的方法。根据该技术，在可能的表面准备后，将待镀层的物体浸入包含想沉积到所述物体上的产品的浴中。然后将物体从浴中取出，去除多余液体，例如通过干燥、固化、聚合化使镀层变得牢固。
该技术最普遍的应用之一是用金属如锌来镀覆钢制零件如带或丝，这种金属后面会对钢制零件提供防腐蚀保护。
在液态金属浴中通过后，已镀层零件经受干燥作业。该作业是浸镀方法中最重要的作业之一，因为它可以控制最终的镀层厚度。一方面，干燥应该在产品的整个表面上、即对于带来说在其宽度上而对于丝来说在其圆周上，以及在待镀层产品的整个长度上是均匀的。同时，该作业应将沉积严格限制于目标值，其或是习惯上用一般为3-50μm的沉积厚度表达，或者以典型地单位为gr/m2的单位面积沉积层的重量来表达。
当前，一般通过气刀或气体射流进行干燥，在带的情况下，气刀或气体射流为线性的，在丝的情况下气刀或气体射流为圆形，气刀或气体射流来自隙口并且常常取向成与待处理表面垂直。气刀如同“气动刮刀”般作用，具有无需机械接触、因此没有刮伤已处理物体风险运行的优点。这种气刀称为“气体干燥器”又或者“干燥刀”。在最精细的应用中，如在处理用于制造汽车车身可见零件的钢带中，使用的压力气体或者是空气，或者是中性气体如氮气。
镀层的最终厚度尤其取决于带的行进速度、带与干燥刀之间的距离，最后取决于压缩气体射流在带上施加的作用力。
然而，已经知道当带在底辊上经过时，带呈瓦状。应借助称为矫直辊(décambreur)的第二辊来矫正这种塑性变形，矫直辊赋予带以反向塑性变形。附带地，称为稳定辊的第三辊可以不受弯曲矫正影响来确定通过线。但是，辊交迭布置控制不好会导致残余变形，并因此导致损坏平整度。
其它现象也可能破坏带的平整度。这可能涉及到在带进入液态金属浴之前，基础钢材质量呈非均质性，轧制条件差，又或加热条件不均匀，带退火周期时温度保持和冷却不均匀。
另外，设备的一些特征如上辊前存在冷却装置、一些辊的偏心性质、浸没辊的滑动或滚动轴承磨损等，导致通过干燥器的带震动。
最后，这些平整度缺陷和这些震动导致镀层厚度变化，这些变化影响产品质量并且为保证对客户的最小镀层厚度而导致锌的过度消耗。
另一方面，对于给定的镀层厚度，当带的速度增加时，需要增大干燥压力。然而，已经知道，带的移动不能超过临界速度，超过该速度会出现喷溅现象(或英文splashing):液滴脱离干燥波，喷射到浴面和设备上。这从而导致产品质量大幅下降，并大大增加了在浴面的泡沫量。
为了解决这些问题，制造商提出使用用于矫正带弯曲并稳定带的气动或电磁装置，或可以避免喷溅的其它装置。还提出过在陶瓷材料制的滑动轴承或滚动轴承上安装浸没辊。
文件JP 56 153136A提出在一些位置安放至少一对气动稳定器或减震器，使得减小底辊与上辊之间的震动长度，底辊与上辊对于带来说是固定的点。
文件JP 56 084452A提出使用气动稳定器，其中，注入流体的一部分沿带向与来自干燥器的流体的相反方向流动。
文件JP 2005298908A提出通过气垫与刮刀结合来避免喷溅，其中气体与液体混合，以便从刮刀下通过。
目标在于稳定干燥器中的带，因而需要使此类稳定器位于干燥器附近，这样意味着在具有最终厚度、但还未固化的镀层上吹送压力气体，从而会存在影响最终产品外观的危险。另外，这些装置不保证干燥器处的带的平整。
还提出过其它流体动力稳定装置，如文件WO 03/054244A1中。但是，该方法需要借助泵在管道中注入液态金属。另外，带插入的管道的宽度不一定与带的规格、镀覆流量或带的行进速度相适应。
另外，还知道一定数量的方法，用于在使用电磁方式的基础上控制或消除影响连续行进金属带的震动(例如参见文件JP 10 298728A、JP 5 001362A、JP 9 143652A、JP1087755A、JP 8 010847A)。
电磁方法建立在以下原理的基础上。将高频电流在其中流通的导体安装在钢带的两侧。它们在带中感应出反相电流，即傅科(Foucault)电流。施感电流与感应傅科电流之间的相互作用产生有稳定钢带趋势的磁压。另一方法在于使用一些电磁体。但是，由于使带趋于不稳定的磁吸力，此类方法要求附加控制。另外，已知使用的高频电流导致带中温度升高，这与在本方法的该步骤中追求的目标相反。
这些不同技术的教导不能完全克服带震动或带缺乏平整的问题，即便最小化了这些问题，但它们一般在干燥刀处仍存在。因此正是需要在此部位作用，而不破坏镀层的形成。
发明内容
发明目的
本发明旨在针对连续行进的金属带的稳定性问题而提出可克服现有技术缺点的一种解决方案。
特别是，本发明旨在通过可消散设备在带中产生的震动能量的流体动力部件，稳定和/或减缓离开液态金属浴的带的震动。
另外，本发明的目的还在于如现有技术中提出的那样，避免紧邻干燥器使用会影响最终产品外观的附加气体射流。
本发明还旨在矫正带的弯曲，更普遍地旨在提高在紧邻实现镀层最终厚度的地点附近、即在干燥器处的带的平整度，以及保证在带平面中的均匀的镀层厚度。
最后，本发明的目的还在于针对高速行进遇到的喷溅问题提供一种解决方案。

图4表示本发明三个优选实施方式的正面图，其一方面与每个垫块背部上存在的通道相关，另一方面与接合垫块之间的界面相关；
图5表示本发明的两个优选实施方式的平面图，表示根据带相对参考平面的弯曲缺陷而在带两侧上相关布置垫块。
具体实施方式
为了阐明想法，图1示意表示本发明的流体动力稳定装置的优选实施方式，该装置与钢带1面对地布置，钢带1在经过液态锌浴2的底辊4、矫直辊5a、可能还有稳定辊5b后并且在通过干燥刀3处之前，被带动进行向上的连续运动(即以竖向带方式)。
本发明的装置的形式主要为至少一个、但一般为多个的被自动对齐(或自动排齐)的流体动力垫块6，垫块安装成围绕铰接件7枢转。垫块是指刚性平面装置如板。垫块或者可以布置在金属浴2之外，或者可以具有部分浸入的部分8，或者可完全浸没。加载垫块6旨在平衡在带-垫块界面处的液态金属膜内产生的流体动力升力，还旨在使带1在离开金属浴时变平整。
更确切的说，完全露出或完全浸没的垫块6有利地允许避免捕集在生产线启动时主要处于金属浴表面的泡沫，而完全露出的垫块有利于尽量靠近干燥器的稳定。而且，部分或完全浸没的垫块6可以有利于预热和通过与金属浴直接接触的热传导保持垫块温度。这样还可以利用恰好在带离开金属浴之前带附近的速度曲线，因此明显提高流体动力升力(Rhydrodyn)，界面处的厚度、因此有关垫块与带之间接触危险的运行安全性都得以改进。
在图2可看到，镀层厚度变化将对应于弯曲缺陷Δz)c和由于震动产生的移动Δz)v。在带更靠近干燥刀而非参考平面12之处，镀层的最终厚度将更小，反之亦然，其中参考平面12从定义上看处于离干燥刀相等的距离Z处。更特别的是，弯曲导致带宽度上的厚度连续变化。刚性或“string(线串)”模式的震动导致沿行进方向上的厚度交替变化，而高阶震动(扭曲或摇摆)导致影响纵向和横向两者的变化。因此，这里提出的装置旨在消除这些不同的变化，以便得到在干燥刀处稳定且平整的带，因而保证在带平面的两个方向上都均匀的镀层厚度。
在图3上可以示意地看到超过带行进的临界速度发生的喷溅现象：对于给定的最终厚度，当带的速度增加时，上升流13和回流14将使干燥波11的厚度膨大。为保证镀层的最终厚度恒定，需要增大干燥压力，因此需增大压力梯度和干燥区20中的流体膜的表面剪切。超过速度-厚度对的临界值，剪切速率导致液态金属小滴15喷射出(泼溅或喷溅)。因此本发明提出通过将优选尖细的垫块6端部布置在干燥区20内，来限制干燥波11的厚度。使垫块6的背部、即与带相反的垫块表面性质上成为非侵润性或通过沉积适当镀层而成为非侵润性，则其效率将更佳。实际上，回流的一部分将在垫块6的背部流动，这样可以避免液态金属通过在此处凝固而结束。
对于宽度一般直到2m的待镀层带，如果要覆盖带的整个宽度，则必须并排地设置多个垫块。在图4上，这些垫块6处于带1的至少一侧上，基本横向延伸在带1的整个宽度上。同样出于上面解释过的原因，每个垫块6的背部有利地至少还具有可以在铰接件支撑部之外引导回流的一个通道或一些沟槽17。可选地，这些垫块6沿横向以一定距离分开，并互相基本平行。在相反情况下，这些垫块可选地可通过陶瓷毡18接触，或者可以在与上升流相反的垫块相邻侧面处通过附接的挡板(chicanage)19嵌接，从而限制干燥后此处镀层超厚的危险。
在图5(A)所示的第一实施方式中，垫块6错开地布置于所示带1的两侧，而带相对参考平面12存在弯曲缺陷。每个垫块6可以通过它的支撑千斤顶承受相同的力，或者特有的力(Fi)(i＝1、2、3……、N)。还是根据本发明，可以将可编程逻辑控制器(PLC)添加到装置中，以便更好地控制结果，控制器有利地允许测量弯曲度、分析缺陷并以闭路矫正力(Fi)。
在图5(B)所示的第二实施方式中，垫块6在带1的两侧互相面对。每对垫块可以通过它的支撑千斤顶承受相同的力，或不同的力(Fi)1-(Fi)2(i＝1、2……、N)。这里有利地还可以考虑使用测量、分析和闭路矫正系统PLC。
至少在一些操作条件下，本发明可以去除矫直辊5a和稳定辊5b，这是更加有利的，因为这些辊在其浸没轴承磨损后会导致产生附加震动，这些辊也导致产生粗糙度，并且它们的维修和更换都需要影响工厂生产率的停工。
也可考虑本发明的其它优选实施方式，这里它们的区别在于实现的减震的性质。例如，可以简单地用千斤顶的“压缩空气-内部摩擦”来替代弹簧-减震器组件10。
