Description

控制轧机中吐丝头的速度的方法
相关申请的交叉参照
本申请要求2007年4月2日提交的美国临时专利申请No.60/909,548的优先权。
技术领域
本发明总的涉及将通常为线材和棒材的热轧轧件形成为线圈的轧机，线圈以重叠的斯宾塞(Spencerian)型式沉积在输送器上，线圈在该输送器上输送到重整工位的同时经受受控制的冷却。本发明具体地涉及用于控制吐丝头转速的改进方法，以优化沉积在输送器上的线圈型式。
背景技术
为了以基本均匀的方式冷却在输送器上输送的线圈，线圈型式最好也应该是基本均匀的。为了实现基本均匀的线圈型式，吐丝头速度应该与轧件速度相匹配。因为轧件速度会由于改变的轧制状态而时时变化，所以必须相应地调节吐丝头速度，假如无法及时地做到这样，则会使输送器上的线圈型式变得混乱。
过去，操作人员基于他们对于输送器上线圈型式的观察来控制吐丝头速度。因此，轧件速度和吐丝头速度之间的差值在它们开始使线圈型式变得混乱之前不会被检测到和注意到，这会不利地影响冷却的均匀性。在操作人员没有经验和/或不注意轧机的改变状态时，这个问题更加突出。
本发明的目的是提供一种保持轧件速度和吐丝头速度之间的最优关系的改进方法。
发明内容
如图3所示意示出的，轧机吐丝头的吐丝管10通常构造有平直的输入区10a、弯曲的中间区10b和弯曲的输出区10c，输入区10a与吐丝管的转动轴线A对准，中间区10b具有从轴线A测量出的逐渐增大的半径，而输出区10c具有一恒定的半径，该半径等于中间区与输出区相接处的中间区10b的最大半径R。
如图4所示，半径R是从吐丝管的中心测量出的，而管壁在该处具有最大和最小内径Rmax、Rmin。
根据本发明，从吐丝管的转动轴线测量而确定吐丝管的最大和最小内径。连续测量进入吐丝管的轧件速度，控制吐丝管的转速，以使吐丝管在其最大和最小内径处的速度包括一包含轧件速度的范围。
现在将参照附图来更详细地描述本发明，在附图中：
附图说明
图1是实际用在本发明中的系统的示意图；
图2A和2B是轧件速度在与吐丝管最大和最小内径处速度相关时的示意图；
图3是吐丝管的示意图；以及
图4是在吐丝管的最大和最小内径处通过吐丝管的剖视图。
具体实施方式
首先参见图1，吐丝头8包括中空衬套12，该中空成套包含吐丝管10。由电动机18驱动的锥齿轮组16用来可转动地驱动吐丝头绕其轴线“A”转动。
例如热轧线材或棒材之类的纵向移动轧件沿着轴线A进入转动的吐丝管，并且形成螺旋形的一系列线圈20，线圈20以重叠的斯宾塞型式被接纳在输送器22上。在已知的方式中，当线圈在输送器上被输送到远处的重整工位(未示出)时，经受受控制的冷却。
根据本发明，最大和最小内径Rmax、Rmin是从转动轴线A测量而确定的。这些测量结果与分别代表电动机18的速度和进入吐丝管10的轧件的线速度Vp的信号26、28一起提供给控制器24。较佳地通过激光测速仪30来连续测量轧件速度，该激光测速仪30的一个例子是由美国麻萨诸塞州伍斯特市的摩根建设公司(Morgan Construction Company of Worcester，Massachusetts，U.S.A.)所供应的“激光速(Laser Speed)”。
已经确定了，假如轧件线速度Vp最优地设置在由吐丝管在其最大和最小内径Rmax、Rmin处的转速Vmax、Vmin所包括的范围内，则可使输送器22上的线圈保持最优且基本均匀的型式。
因此，控制器24连续地计算Vmax、Vmin，并且在显示器34的屏32上可视地显示结果以及轧件速度Vp。该信息如图2A所示显示在屏32上。这里，轧件速度Vp最优地设置在由吐丝管到达最大内径速度和最小内径速度Vmax、Vmin所包括的范围RA内。
假如轧制状态导致轧件速度的改变，例如如图2B所示引起增大，则操作人员通过观察显示器34就可立即被警告需要通过调节吐丝头的速度来重新设置范围RA，在所披露的例子中，通过增大速度，可将Vmax和Vmin从先前设定值(用虚线示出)增大到新提高的设定值，该新提高的设定值继续将轧件速度最佳地设置在包括范围内。
除了手动实施这些调节之外，控制器24可用已知的方式编程以自动实施这些调节。
根据前述，熟悉本领域的技术人员现在会意识到，在首先轧制轧件时，可以确定Rmax、Rmin，可以计算Vmax、Vmin以与预期的轧件速度Vp相匹配。在继续轧制时，可以手动地或自动地迅速调节范围RA，以最优地包括Vp，从而在输送器上获得且保持最优的线圈型式。
