摘要
取向硅钢热轧板中织构梯度对发展完善的二次再结晶十分关键,通过添加铜可以显著降低取向硅钢板坯加热温度,从而影响热轧板织构分布。利用X射线衍射仪,分析了实验室模拟薄板坯连铸连轧(TSCR)工艺的3种不同铜含量的取向硅钢热轧板织构。结果表明:不同铜含量热轧板表面到厚度1/4处均为弱的热轧织构,热轧板心部主要为{100}面织构;铜含量约在0.4%时,热轧板次表层的{110}<001>织构比例最高,而热轧板心部的{100}<110>织构比例最低;铜含量对热轧织构中{114}<110>和{001}<100>织构发展有显著影响。
The texture gradient in hot rolled grain oriented silicon steel strip is one of the essential factors to achieve a perfect secondary recrystallization. The addition of copper can significantly reduce the slab reheating temperature of grain oriented silicon steel, so as to impact the texture distribution in the hot rolled strip. The texture of hot rolled grain oriented silicon steel strip as-rolled by thin slab casting and rolling process （TSCR） in laboratory with three different copper contents was analyzed by using X-ray diffraction tester. The results show that the main texture from the surface to 1/4 thickness in the hot rolled strip of different copper contents is the weak hot rolling texture, and the main texture in the center is { 100 } texture. When the copper content is about 0.4 %, the fraction of {110}〈001〉 texture in the near surface layer of hot rolled strip is highest, while the fraction of {100 } 〈 110〉 texture in the center of hot rolled strip is lowest. The copper content may significantly influence the development of { 114} 〈110〉 and { 001 } 〈100〉 textures in hot rolled grain oriented silicon steel strip.
