摘　　要：电磁性能和板形是无取向电工钢的重要产品特性,卷取温度作为生产控制中一个重要的工艺参数,对它们有重要影响。本研究通过大生产实验,发现高温卷取、U形卷取的层流冷却方式可以有效促进晶粒长大和均匀热轧带钢组织,并进一步提高无取向电工钢的电磁性能,但是会增大带钢纵向厚度的波动,对带钢横向厚度的控制无显著影响。The magnetic property and the shape of strip are two most important properties of non-oriented electrical steels, and the coiling temperature of hot-rolling process, as one of the most important process parameters, can affect those two properties very well. It is found that higher temperature coiled steels with U-shape laminar flow cooling mode have improved magnetic properties and worse strip shape than those of lower temperature coiled steels.
