Description

乳化液低惯性力回流阻断装置 技术领域
本发明属于冷轧乳化斑处理技术领域，具体涉及一种单机架可逆冷轧机在轧制道次切换时乳化液低惯性力回流的阻断装置，应用于各类冷轧轧机机组。
 背景技术
单机架可逆冷轧机在轧制道次切换时，在轧制速度低于4m/s时，有大量用于轧制润滑的乳化液向入口侧回流，造成成品钢卷的带头、带尾部分存在大量的乳化液残留物，不仅降低冷轧产品的成材率，而且增加了轧制油的消耗。传统上采用在轧机的入口以及出口处增设挤干辊，如图1所示,用挤干辊阻断乳化液的回流。在图1中,入口处的入口挤干辊3在挤干过程中会将机架内回流的乳化液甩向入口,影响测厚仪的正常工作,同时,由于甩出的乳化液不方便收集，因此造成乳化液耗量增加。在出口侧，由于出口挤干辊5的投入，改变了出口卷取机与机架间的张力分布，造成板形控制困难。
 技术问题
本发明的目的在于提供一种结构简单的乳化液低惯性力回流阻断装置。

 有益效果
本发明的有益效果是：采用上述结构，其结构简单。应用本发明的乳化液低惯性力回流阻断装置，可阻止轧机低速轧制时的乳化液回流。

 本发明的最佳实施方式
如图3、4所示，乳化液低惯性力回流阻断装置，它包括升降装置、支架、上衬板22、下衬板23、连接螺栓、橡胶刮板24，支架固定在升降装置上（升降装置带动支架升降），支架上设有滑槽，下衬板23的上端设有滑块，滑块位于滑槽内，橡胶刮板24的上端部位于上衬板22与下衬板23之间，上衬板22、橡胶刮板24和下衬板23由连接螺栓固定连接（橡胶刮板24能升降；并能左右移动，调整与带钢的左右位置）。
所述的升降装置包括带编码器14的电机15、第一涡轮蜗杆装置16、连接杆17、第二涡轮蜗杆装置25，电机15的输出轴由联轴器与第一涡轮蜗杆装置16的旋转输入轴相连，第一涡轮蜗杆装置16的旋转输出轴由联轴器与连接杆17的右端相连，连接杆17的左端由联轴器与第二涡轮蜗杆装置25的旋转输入轴相连；第一涡轮蜗杆装置16的升降杆由右压紧螺母12与支架的右底板13固定连接，第二涡轮蜗杆装置25的升降杆由左压紧螺母与支架的左底板26固定连接。
所述的支架包括右侧板11、右底板13、滑槽体21、左压紧盖18、右压紧盖、左底板26、左侧板27，滑槽体21上设有滑槽（下衬板23的上端的滑块位于滑槽内），滑槽体21的右端由右压紧盖与右底板13固定连接（滑槽体21的右端***右压紧盖内，右压紧盖与右底板13固定连接），滑槽体21的左端由左压紧盖18与左底板26固定连接（滑槽体21的左端***左压紧盖内，左压紧盖与左底板26固定连接）；右侧板11的上端与右底板13固定连接（如焊接），左侧板27的上端与左底板26固定连接（如焊接）。

应用：如图2所示，本发明采用橡胶刮板方式阻止轧机低速轧制时的乳化液回流。
在轧机切换完轧制道次后，入口侧乳化液低惯性力回流阻断装置的橡胶刮板24在电机15、涡轮蜗杆装置16驱动下压至带钢表面，橡胶刮板24的压下行程由电机自带的编码器14进行控制。确认橡胶刮板24压下到位后，轧机起步开始轧制，乳化液与速度关联开始投入轧制。当乳化液出现回流时，橡胶刮板24阻止乳化液回流，保证机组的正常轧制。当轧制速度进一步升高，乳化液在惯性力作用下被高速轧制的带钢带入机架，当机组提速到4m/s时，入口侧乳化液低惯性力回流阻断装置的橡胶刮板24在电机15、涡轮蜗杆装置16驱动下自动抬起。在此过程中，出口侧乳化液低惯性力回流阻断装置的橡胶刮板始终处于抬起位。防护辊20在机组出现断带时保护橡胶刮板不被打坏。
