低温高磁感取向硅钢热轧板通电加热织构研究

Texture study of hot rolled plate by electric heating for low temperature high magnetic induction grain-oriented silicon steel

通过对低温高磁感取向硅钢热轧板通电加热处理,发现将热轧板以55℃/s从室温加热到1000℃后降温,在1000~950℃降温过程中保持时间2~5 s,可以获得与常化工艺等效的热轧板织构组分,根据所得结果,讨论了在热轧轧机后段增加电加热装置,从而代替常化工艺生产高磁感取向硅钢的可能性。

The hot rolled plate of low temperature high magnetic induction grain-oriented silicon steel was treated by electric heating.The experimental results showed that the hot rolled sheet with equivalent normalizing plate texture components can be obtained by heating hot rolled sheet from room temperature to 1000℃with a rate of 55℃/s and then cooled which involved maintain 2-5 s during the cooling process from 1000℃to 950℃.The possibility of adding electric heating devices in the back section of hot rolling mill was discussed according to the experimental results.
