热轧轧制工艺对产品性能和轧制稳定性影响很大,对中低牌号无取向电工钢,当在两相区轧制时,热轧塑性明显降低,板形变坏,易出现边裂等情况。以50W1000为例,通过对其变形抗力进行研究,得出把两相区控制在F4与F5之间为最佳轧制工艺的结论。在此基础上制定了一套较为合理的热轧工艺制度。采用新的轧制工艺后,50W1000热轧精轧的稳定性明显改善,热轧产品合格率由开发初期的40%左右提高到95%以上。 The hot rolling process has great influence on product′s performance and rolling stability.For the low medium grade non-oriented electrical steel,when non-oriented electrical steel is rolled in tow phase region,the hot rolling plasticity reduces obviously,the shape of strip goes bad and easily to crack at the edge.The deformation resistance of 50W1000 steel was investigated.The results show that the optimal rolling process is to control the two phase region between F4 and F5.Based on the results...

提出了一种基于爱泼斯坦方圈族(包括标准25cm爱泼斯坦方圈、缩比的17.5cm和20cm爱泼斯坦方圈)和二级加权处理方法对爱泼斯坦测试数据,包括有效磁路长度、比损耗、励磁功率,进行处理的晶粒取向电工钢磁性能扩展模拟方法。详细地考察了励磁频率、试样剪切角度和环境温度对爱泼斯坦方圈测量结果的影响。研究结果表明,利用本文提出的爱泼斯坦方圈组合以及二级加权处理技术,可以有效地建立取向电工钢损耗模拟模型,从而更加准确地确定了取向电工钢的损耗,改善并提高了爱泼斯坦磁性能测试数据的应用价值。 The extended modeling of the magnetic properties of GO(grain oriented) electrical steel is presented in this paper which is based on a set of standard and scaled-down Epstein frames and a proposed two-level weighted processing of Epstein data, including the mean magnetic path length, specific magnetization loss and exciting power. The effects of excitation frequency, strip angle and ambient temperature on the results obtained from the Epstein frames are investigated. It is shown that using the p...
