Hot rolling is the key factor for controlling transverse thickness difference, especially edge drop, of non - oriented silicon steel.
热轧是控制无取向硅钢成品横截面厚差偏大、尤其是边部减薄显著的关键工序。

Through axial movement of work roll and cooperating with hydraulic bending roll technology, WRS rolling mill can increase plate shape controlling capability and can improve edge thinning of plate.
WRS轧机通过工作辊的轴向移动，配合液压弯辊技术，提高了板形控制，改善了边部减薄。

The distributing of intensity of pressure is determined when polished die is baring partly and the controlling means of edge effect are generalized.
