Abstract

一单线式线材轧机，产品在其中经过一系列精轧 机座以无扭方式轧制后进到卷线头。精轧机座至少 组合成第一和第二两个精轧组，分别沿不在同一条直 线上的第一和第二通道设置。卷线头则置于第二通 道。采用一些换向机来交替地将从第一组出来的产 品或导引至第二通道，使其在第二组中继续轧制之 后，再导引到卷线头，或沿第三通道导引，绕过第二 组，直接通向卷线头。从而可便于调整产品尺寸，减 少停机时间。

Description

本发明涉及用于线材类轧制的连续热轧机，特别是这类轧机精轧部分布置的改进。
线材轧机的精轧部分位于轧机的中轧部分和卷线头之间。后者将精轧产品成形成环圈，以便随后放置到一冷却传送机上。
一般，精轧部分包括多个精轧机座，用机械连接到一共用驱动装置上，通常称之为一个“精轧组”。该精轧组及其相关设备，包括冷却水箱、剪切机、夹送辊等通常均沿一通向卷线头的共用通道设置。
这种布置不便于轧机操作者将一种产品尺寸换至另一种。当试图在较低温度范围内，轧制较小尺寸的产品时还会遇到其它的困难。
本发明的目的是对轧机精轧部分提供一种新颖和改进的布置，从而提高了轧机在精轧产品的尺寸和精轧的温度方面的灵活性。
本发明的另一个目的是在从一个产品尺寸转换到另一个时，减少通常所需的昂贵的停机时间。
本发明是通过将各精轧机座至少组合成第一和第二两个精轧组、并分别设置在不处于同一直线上的第一通道和第二通道上来实现其目的和体现其优越性的。卷线头位于第二通道，通过换向机和侧位活套装置，使从第一精轧组出来的产品可以沿第三通道、绕过第二精轧组加工成直径较大的精轧产品，直接送至卷线头。也可以再转到第二通道，在第二精轧组进一步轧制成直径较小的精轧产品送到卷线头。
特别值得指出的是产品是沿着与第二通道处于同一直线上的上游通道送入轧机的精轧部分的。第一通道与第二通道是平行的，而第三通道则从第一通道以某一角度延伸至第二通道。
图1为精轧部分符合本发明的线材轧机原理图。
图2为将图1所示的精轧部分放大且更为详细的原理图。
首先参见图1，图中所示的轧机包括：一座钢坯再热炉10，含有多个粗轧机座12的粗轧部分R，含有多个中轧机座14的中轧部分I和包含第一和第二精轧组16、18的精轧部分F。这里所采用的术语“精轧组”定义为由一共用驱动装置驱动的机械上互相连接的一组轧制机座，工作辊设置成以无扭方式轧制产品。美国专利第4537055号公开了精轧组的一个典型例子。
精轧部分F位于中轧部分I和将精轧产品成形为环圈22的卷线头20之间。环圈置于冷却传送机24上冷却之后，在卷材成形工段26中再成形为卷材。
再参见图2，可看到第一和第二精轧组16、18分别沿相平行的第一和第二通道P1、P2设置。第一精轧组16后面是一组水箱28，然后是换向机30。操纵换向机30，可交替地将从第一精轧组16出来的产品或导引至绕过第二精轧组18并交汇于第二通道P2上的下游换向机32处的第三通道P3，或导引至交汇于第二通道P2上的位于第二精轧组18之前的换向机34处的第四通道P4。沿第二通道P2在换向机34和第二精轧组18之间，设有一个侧位活套装置36和一台剪切机38。还有一组水箱40设在第二精轧组的下游。
来自轧机中轧部分I的产品沿着与第二通道P2成一直线的上游通道P5进入。有一组水箱42设置在通道P2、P5交接处的换向机44之前。一条分通道P6从换向机44通向第一精轧组16，沿通道P6位于换向机44和第一精轧组16之间，设置有一套从动夹送辊46、一个侧位活套装置48和一台剪切机50。
图2的布置能有效地适应相当宽广的产品尺寸范围和轧制和卷线温度范围。例如，小直径产品可以这样来轧制：通过设定换向机44、30、34和32，将产品从通道P5沿通道P6、P1、P4和P2导引，在精轧组16和18中进行连续轧制。侧位活套装置48和36将确保进入各自下游精轧组的产品的张力既不过大也不过小。水箱42、28和40则可用来控制轧制和卷线温度以适应各种不同的运行参数。
较大尺寸的产品可以这样来轧制。通过重新设置换向机30、32，将从第一精轧组16出来的产品沿通道P3导引，从而绕过第二精轧组18。操作人员可利用第二精轧组的生产间隙进行各种工作，比如，替换磨损了的导轨和/或轧辊。试轧所选机座以适应产品尺寸的变化，使该轧组准备接受直接来自轧机中轧部分I的产品等等。在后一情况中，换向机44、34可据此调整以绕过第一精轧组16，从而使操作人员能够在经过第二精轧组18继续进行轧制时，进行类似的维修工作。
在上述所有情况中，均可采用同一个卷线头20来卷绕经精轧机轧制出的产品。
