摘要/Abstract

摘要： 研究了≤0．005％C-2．5％～2．8％Si的2．5 mm热轧电工钢板在850～1 100℃常化对0．5 mm冷轧板880℃+950℃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,磁感呈单调递增趋势;热轧板常化温度超过1 000℃,因第2相固溶而后弥散析出,退火冷轧晶粒细化,铁损增加,因此该钢热轧板最佳常化温度为1 000℃。

Abstract: The effect of 2.5 mm hot rolled plate of electric steel(≤0.005%C-2.5%～2.8%Si)normalizing at 850 ~1100℃ on structure and magnetic properties of 0.5 mm cold rolled sheet annealed at 880 ℃+ 950 ℃ has been studied.The results showed that with increasing normalizing temperature of hot rolled plate,the recrystallized grain size of annealed cold rolled sheet increased,iron loss reduced and magnetic induction monotonically increased; as normalizing temperature was more than 1000 ℃,with solid solution second phases then precipitated dispersed in annealed cold rolled sheet,the grain fined and iron loss increased. The optimum normalizing temperature of hot rolled plate is 1000 ℃.
