Description

一种面向板带轧制过程的高效稳定施加电流推床及其方法 技术领域
本发明涉及轧制设备技术领域，尤其涉及一种面向板带轧制过程的高效稳定施加电流推床及其方法。
背景技术
轧机是冶金工业领域常用的机械设备，为了适应工业发展，探索新工艺下的轧制方法显得尤为重要。新工艺下就需要新设备的设计支撑新工艺的实施。
研究表明电致塑性效应可以大幅提高材料的成形极限，并且电流辅助成形工艺已经在很多领域取得较好的应用效果。电致塑性效应在材料成形过程中不仅对力学性能有影响，而且对回复、再结晶也有影响，可以达到改善材料微观组织的目的。电流辅助加工过程中，常常通入瞬时高能脉冲电流，可以使材料在极短的时间内获得足够能量，促进位错的移动来提高再结晶速率和再结晶的形核率，使材料在低于理论再结晶温度下发生再结晶。
目前在板带轧制领域内，相关学者多将脉冲电流用于薄带冷轧，电流直接通过轧辊或者带材两端简单加载，施加方式简易，且将电流直接作用于轧辊会导致轧机整体带电，造成安全隐患，同时电流流经大辊径轧辊时会造成电流损耗且容易降低轧辊使用寿命。同时将脉冲电流用于尺寸有限的金属板带轧制过程实现困难，因此亟需一种用于金属板带轧制领域的脉冲电流施加装置与***，以解决上述问题。

第一机架2、第二机架3上方分别设置有若干用于送料的陶瓷辊4，陶瓷辊4两侧设置有脉冲电流施加组件；
第一机架2上的陶瓷辊4上方设置有料厚检测机构，轧机1出料侧与陶瓷辊4之间设置有整平板材的压下机构。通过第一机架2上的陶瓷辊4将板材送入，通过第二机架3上的陶瓷辊3将板材送出，板材在轧制过程中通过陶瓷辊4两侧的脉冲电流施加组件对板材施加电流，料厚检测机构用于检测入口处板材厚度，压下机构基于厚检测机构测得的厚度数据，结合压下率、轧制速度等参数，估算出板带的翘曲度，并于板材出口时，将板材压下，保证出口板带可顺利进入出口脉冲电流施加组件中。
进一步优化方案，脉冲电流施加组件包括对称设置在陶瓷辊4上方的柔性挡板5，两个柔性挡板5相对的侧面上转动连接有滚轮501，滚轮501外接有脉冲电源，柔性挡板5底部连接有对正夹紧部。通过滚轮501为板材施加脉冲电流，对于容易边裂的材料，通过该装置施加脉冲电流能够提高边部温度，抑制边裂发生，同时利用电致塑性效应能够有效降低材料变形抗力，促进材料再结晶，消除轧后残余应力；对于复合板轧制，能够有效夹紧对正各层材料，有效抑制轧制过程中异种材料尚未轧制区域分叉，实现脉冲电流高效稳定加载。
进一步优化方案，对正夹紧部包括对称设置在陶瓷辊4端部外侧的第一支架7，两个第一支架7之间固定连接有至少两个滑动支撑杆703，滑动支撑杆703上滑动设置有滑动块713，滑动块713固定连接有随动挡板708；
两个第一支架7之间转动连接有第一丝杠701和第二丝杠702，第一丝杠701、第二丝杠702上分别配合设置有两个丝杠螺帽707，丝杠螺帽707、滑动块713固定连接在随动挡板708上；
滑动块713上方固定有移动滑轨711，移动滑轨711上方滑动设置有与移动滑轨711相配合的滑块712，柔性挡板5与滑块712固定连接；
随动档板708上部设置有从动板709，从动板709与柔性挡板5之间固定连接有弹簧710；
第一丝杠701端部轴接有第一皮带轮705，第二丝杠702端部轴接有第二皮带轮706，第一皮带轮705、第二皮带轮706通过同步齿形带传动连接有第一伺服电机704。两个丝杠螺帽707内的螺纹方向相反，第一丝杠701、第二丝杠702上与丝杠螺帽707匹配设置有双向螺纹，第一伺服电机704转动，带动第一皮带轮705、第二皮带轮706转动，从而带动第一丝杠701、第二丝杠702转动，从而丝杠螺帽707沿相对方向运动，丝杠螺帽707带动随动挡板708沿相对方向运动，随动挡板708带动柔性挡板5沿相对方向运动，从而实现对板材的夹紧对中。
进一步优化方案，料厚检测机构包括固定设置在第一机架2上方的第二支架6和固定连接在第二支架6中部的光栅测厚仪601，光栅测厚仪601位于陶瓷辊4上方。通过光栅测厚仪601检测入口处板材厚度，并将板材厚度信息传递至压下机构。
进一步优化方案，压下机构包括固定连接在第二机架3上方的第三支架8，第三支架8中部固定连接有第三伺服电机801，第三伺服电机801输出轴固定连接有丝杠组件，丝杠组件的丝杠与第三伺服电机801输出轴固定连接，丝杠组件的螺母固定连接有滑动板808，滑动板808两端上方固定连接有导向杆802，滑动板808下方活动设置有压板804，压板804两端固定连接有滑杆807，滑杆807外侧设置有补偿弹簧805，压板804中部转动连接有下压轮806，第三支架8上固定连接有与导向杆802匹配的导套，滑动板808上固接有与滑杆807相匹配的滑套803。通过控制第三伺服电机801下压，第三伺服电机801输出轴带动滑动板808向下运动，滑动板808带动压板804向下运动，板材从轧机1出口出来后与压板804接触时，受补偿弹簧805的弹力作用，可有一定的调整范围，因为入口计算翘曲度时估算的不是完全准确的，通过设置补偿弹簧，可以实现对出来的板材的柔性调整，通过在压板804中部设置下压轮806，可以避免板材与压板804之间的摩擦。
进一步优化方案，第一机架2、第二机架3上方固定连接有安装板402，陶瓷辊4两端转动连接在安装板402上，陶瓷辊4两端轴接有同步带轮403，第一机架2、第二机架3上方固定连接有第二伺服电机401，第二伺服电机401通过 同步齿形带、同步带轮403驱动陶瓷辊4。

进一步优化方案，对第一机架2、第二机架3任意一个上的两个脉冲电流施加组件施加脉冲电流正极，对未施加脉冲电流正极的第一机架2、第二机架3上的两个脉冲电流组件施加脉冲电流负极。
