Abstract

使用斯特格尔轧机进行轧制时,在待轧带材长度上出现显著的轧制压力波动。这些由带材不同的温度引起的轧制压力波动将通过根据带材温度和/或带材位置进行调整的加热装置而得以均衡,这样在带材全长范围内便显示出大约不变的轧制压力。

Description

斯特格尔轧机
本发明涉及一种带有至少一个可逆式机座和设置在可逆式机座入口侧和出口侧的夹送辊和卷炉的斯特格尔轧机,上述装置是通过一些传送待轧带材的辊道被彼此连接的。
上述类型的斯特格尔轧机早已公知了。它的工作过程如下所述:在入口侧的卷炉中通过入口侧夹送辊把初轧过的带材导入可逆式机座以进行第一道次轧制。第一道次轧制后把轧材送入出口侧卷炉中。该带材在出口侧卷炉中被卷起之后,在上述卷炉和可逆式机座之间形成预先确定的带钢张力,并且以相应的速率对带材进行轧制。如果带钢尾进入斯特格尔轧机,则要以这样的方式对该装置进行制动,即让带钢尾虽在可逆式机座的辊缝之后但要在出口侧夹送辊之前进入停止状态。换向时为下一道次轧制而调整辊缝。出口侧夹送辊将带材导入可逆式机座以进行第二道次轧制。第二道次轧制工序后,把带材送入入口侧的卷炉中。第二道次轧制结束时,带钢头在入口侧夹送辊和可逆式机座之间进入停止状态。
由制动、送出、换向、咬入和送入确定的换向过程中,带钢头尾相对中间部分冷却较快。冷却较快的结果是由于换向过程中,带钢的头或尾无法在卷炉中保温。此外,当带钢头尾在已调至确定温度的变冷的卷炉的卷绕心轴上被卷起时,至少在第一道次中带钢头和尾部发生了附加冷却。
由于带钢的冷头和冷尾部分,轧制过程中此处的轧制压力相对带材中部明显升高。因此可逆式机座必须设计成能适应在此出现的高轧制压力。由于在带钢的冷头和冷尾部分的轧制压力峰值很大,结果在轧制带材的长度上可能会出现厚度和/或平坦度的变化。轧材质量便因此变差或出现相当高的废品量。
本发明的任务在于,如此设置斯特格尔轧机,即轧制压力在带材长度上没有显示出大的波动,带材轧制时质量不变并避免了废品。
本发明任务通过权利要求1的技术特征得以解决。在此提出的解决方案的结果是,首先可以把未处于加热卷炉中的轧制带材的部分加热至一个与其余的轧制带材一致的合适的温度,这样至少从轧制带材长度上的温度变化曲线看,轧制压力没有很大的波动。
如权利要求2提出的那样,有意义的是在可逆式机座的每一侧都有一个加热装置,因而不仅在可逆式机座前进入停止状态的带钢头而且在可逆式机座后进入停止状态的带钢尾都能保持温度。
通常,入口侧和出口侧的夹送辊设置得十分靠近各自的卷炉,因此完全能够在夹送辊和可逆式机座间设置加热装置。
为了对带钢头或带钢尾进行快速可靠的加热,辊道的上、下方都可设有加热装置。由于辊道上、下方设有相应的加热装置,所以在加热过程中应适当地根据需要单独或总体地考虑这些加热装置。
如权利要求5提出的那样,当采用感应式加热装置时,控制加热过程是非常简单和精确的。
带有处理带材温度的理论值和带材温度的实际值的调节装置的加热装置的优点在于:不仅能够根据需要加热带钢头或尾,还可以测定出带材范围内变冷的区段并对其加热,这是假定上述区段的温度低于规定的带材温度的理论值情况下。在这种情况下,象通常在调整技术中一样,有意义的是允许带材温度的实际值有一定的带宽,以免加热装置在已经很小的带材温度波动情况下不断地断开或接通。此外,如权利要求6的技术特征所述,取决于位置的带材加热和对由带材位置和带材温度决定的加热装置的综合控制是可以实现的。
如果设置一个开关装置,每次仅起动在带材运动方向上总是布置在可逆式机座前的那个加热装置,这样可以保证带材在可逆式机座中的道次轧制之前得到相应的加热,而从可逆式机座出来的带材不再经受加热过程。
下面根据附图进一步描述发明。在此,附图所示为斯特格尔轧机1。该斯特格尔轧机1由一个斯特格尔轧机机座2、两对夹送辊3,3′、两个卷炉4,4′和一条斯特格尔轧机机座2与所说夹送辊3,3′和卷炉4,4′相连的辊道5构成。辊道5,5′的作用是将带材6引入(5′)斯特格尔轧机1或引出(5″)斯特格尔轧机1。
在夹送辊3,3′之间,辊道5的上、下方均设有加热装置7,7′和8,8′。这些加热装置7,7′和8,8′与一个调节装置9的输出端相连。计算器12可以通过输入线路10和输入线路11分别把带材温度的理论值和带材位置的理论值输入给该调节装置9。然而上述带材理论值也可以通过输入线路13、14由输入设备15进行输入。
带材温度的实际值通过带材温度实际值发送器16,16′输入给调节装置9,同时带材位置的实际值可通过一个带材跟踪装置17输入给调节装置9,该带材跟踪装置是从安装在轧机中确定位置(未示出)处的发送器得到多种不同输入信号的。
因此通过上述调节装置9,依赖于带材温度和/或带材位置和/或带材运动方向,可以根据需要在0-最大功率之间调整加热功率。
