摘要
高强度无取向硅钢对成品试样的电磁性能、机械性能均要求很高。为了研究化学成分设计对高强度无取向硅钢成品试样的电磁性能、机械性能的影响,本实验结合3%Si无取向硅钢,探讨了1%Cu、Ni、Cr元素对高强度无取向硅钢,过程试样的显微组织和成品试样电磁性能、机械性能的影响。结果表明,退火温度分别为800℃、850℃C、900℃C时,成品带钢的铁损均表现为Cu>Ni>Cr。但是,随着退火温度的升高,三者之间的差距逐渐缩小,并逐渐趋于一致。同时,退火温度分别为800C、850C、9002时,成品带钢的磁感均表现为Ni>Cr>Cu,三者之间的差距基本稳定。此外,随着退火温度的升高,含Cu、Ni、Cr试样晶粒尺寸逐渐增大,并逐渐趋于一致,试样的抗拉强度、屈服强度、延伸率以及屈强比几乎均呈线性趋势降低,但含Cu试样的屈强比最高,约为79%-84%,而含Cr、Ni试样的屈强比相对较低,约为74%-80%。
There is a strict technical requirement on electromagnetic properties and mechanical properties for the finished steel sheets of high strength non-oriented silicon steel.In order to research the effects of chemical composition design on the electromagnetic properties and mechanical properties of high strength non-oriented silicon steel,the 3%Si non-oriented silicon steel was used for present work to discuss that the effects of 1%Cu,Ni and Cr on the change of the processed microstructure and the finished electromagnetic properties and mechanical properties.The results show that the core loss variation is Cu>Ni>Cr during the annealing temperature range of 800℃ to 900℃ which the gap of the core loss of Cu,Ni and Cr decreases with the increase of annealing temperature and tends to be uniform.Meanwhile,the magnetic induction variation is Ni>Cr>Cu during the annealing temperature range of 800 ℃ to 900℃ which the gap of the magnetic induction of Cu,Ni and Cr tends to be uniform with the increase of annealing temperature.Moreover,the grain size of the finished steel sheets increases with the increase of annealing temperature for containing Cu,Ni and Cr and tends to be uniform.Thus,the Tensile Strength,Yield strength,Elongation and yield ratio nearly decreases by the linear trends.The yield ratio of the finished steel specimen containing Cu is the best about 79%-84%,and the specimen containing Cr and Ni is relative less about 74%-80%.
