1前言在取向硅钢生产中,热轧板常化可以使组织均匀并使材料软化,便于冷轧,也为初次和二次再结晶过程中大晶粒的长大提供了有利条件。即,如果不常化,初次晶粒就不能充分长大,也就不能很好的形成二次再结晶织构。因此就不能得到最优的组织和磁性能。热轧板常化过程中很多可能的变
1 Introduction In the production of oriented silicon steel, the normalization of hot-rolled sheets can make the microstructure even and make the material soften, easy to cold-rolled, and also provide favorable conditions for the growth of large grains in the primary and secondary recrystallization processes. That is, if not normalized, the primary crystal grains can not grow sufficiently and the secondary recrystallization texture can not be well formed. Therefore, optimal microstructure and magnetic properties can not be obtained. Many possible changes in the hot plate normalization process
