本发明阐述一种生产晶粒取向硅钢的改进方法。在以硼为抑制剂的硅钢中,(110)[001]织构的发展取决于二次再结晶的完善程度。在初次晶粒的正常长大被抑制的情况下,二次高斯晶粒吞并初次晶粒而长大,而抑制剂(如:硼、硫、氮)阻碍正常晶粒长大的作用直到二次高斯晶粒长大及初次晶粒消失的温度为止,这种现象是在最终织构退火期间发生的。一般的最终织构退火包括,以接近28℃/小时的速度加热到发生钢质净化的温度,并且在
The present invention describes an improved method of producing grain-oriented silicon steel. In boron-based silicon steel, the development of (110) [001] texture depends on the degree of sophistication of secondary recrystallization. In the case of the normal growth of the primary grains being suppressed, the secondary Gaussian grains engulf the primary grains and grow up while the inhibitors (eg, boron, sulfur, nitrogen) impede the normal grain growth until secondary The phenomenon of Gaussian grain growth and the temperature at which primary grains disappear occur during the final texturing anneal. A typical final texture anneal involves heating to a temperature at which steel cleanup occurs at a rate of near 28 ° C / hr and at
