本发明涉及卷取领域，具体涉及硅钢卷取机卷筒结构，包括机架、收卷辊和按压捆绑机构，按压捆绑机构位于收卷辊一侧，按压捆绑机构包括按压单元和捆绑单元，捆绑单元包括捆绑辊、转动辊、成卷的胶带和两个滑块，两个滑块均滑动设置于机架上，滑块的下端固定有能与机架相抵的下卡块，捆绑辊固定设置于两个滑块之间，捆绑辊上设有凹槽；按压单元包括两个按压部，每个按压部包括按压管和弹簧，按压管通过弹簧与凹槽的侧壁连接，转动辊设置于按压管内，成卷的胶带套设于转动辊上，凹槽的侧壁设有供胶带通过的通槽。采用本技术方案时，有利于避免成卷的硅钢卷松动且能对硅钢卷进行捆绑。

本发明公开了一种取向硅钢高温退火底板，涉及钢卷生产技术领域，解决了钢卷的尺寸变形导致钢卷切边量过大的技术问题。包括应变诱导板，应变诱导板的板面开设有若干凹槽，相邻凹槽之间于应变诱导板的板面形成凸楞，钢卷放置于应变诱导板的板面上，其中部分的钢卷端面支撑于凸楞上，其余的钢卷端面悬置于凹槽上。本发明通过在应变诱导板上设置凹槽与凸楞，钢卷在高温退火过程中同样受重力产生蠕变变形，但蠕变变形按照凸楞所设定的方向进行，从而将产生的不均匀的“大浪”分割成碎化均匀的“细浪”，使得钢卷边部的变形细小、均匀、可控，从而降低了大象脚变形的缺陷影响程度，减小了钢卷的切边量，提高了成材率，同时能够获得良好的边部板形。
