研究了CSP工艺生产≤0.005%C-1.1%Si的2.2mm无取向电工钢热轧板在800~1000℃常化对0.5mm冷轧板840℃退火后组织和磁性能的影响。结果表明,热轧板常化温度升高,冷轧板退火后的再结晶晶粒增大,铁损降低,磁感增加;热轧板常化温度超过900℃,因第二相固溶而后弥散析出,退火后冷轧晶粒细化,铁损增加,因此该无取向电工钢热轧板最佳常化温度为900℃。 The effect of normalizing at 800-1000℃ of CSP produced plate(≤0.005%C-1.1%Si) on the microstructure and magnetic properties of downstream cold-rolled non-oriented electrical steel annealed at 840℃ was studied.Results show that with increasing normalizing temperature of hot-rolled material the recrystallized grain size of annealed sheet increases,iron loss reduced and magnetic induction increases.As normalizing temperature excesses 900℃,grain is refined and iron loss increases after annealing due...

对CSP流程生产的无取向电工钢M50W800不同尺寸样品的磁性能进行了测试和分析,结果表明:采用不同单片检测的磁性能结果与标准的Epstein方圈样品检测对比,存在明显的偏差;且同一尺寸的单片纵横向样品之间相比较,对应的磁性能差异性也较大。几种不同尺寸的单片样品,以320mm×30mm尺寸的纵横向平均值最接近标准Epstein方圈样的性能值,其铁损偏差最小。 The magnetic properties of M50W800 non-oriented electrical steel produced by CSP process were tested and analyzed with samples of different sizes,showing that significant deviation existed compared to that of Epstein square circle sample.In particular,obvious difference in magnetic properties also existed between longitudinal and transverse samples of the same size.For test samples of different sizes,the average magnetic properties of 320mm×30mm samples are the closest to that of Epstein square ...
