摘　　要：对不同板坯加热温度的含铌取向硅钢热轧板进行一次冷轧,通过SEM、EBSD等研究方法研究不同板坯加热温度的热轧板在一次冷轧后的织构演变规律。结果表明:当板坯加热温度由1270℃降至1170℃,一次冷轧后获得的旋转立方织构及高斯织构强度均明显下降,旋转立方织构下降幅度为49%,高斯织构强度下降幅度为82%;冷轧后获得的{111}<112>织构强度与板坯加热温度呈负相关,当板坯加热温度由1170℃增至1220℃,一次冷轧中{111}<112>织构强度下降58%。Effect of slab heating temperature on the texture evolution of Nb contained grain-oriented silicon steel plate prepared by single cold rolling method was studied by means of EBSD and other research methods. The results show that the texture strength of the cube texture and the Goss texture in the single cold rolled plates decreases significantly with the decrease of slab heating temperature from 1270 ℃ to 1170 ℃,the texture intensity of the cube texture decreases by 49% and the texture intensity of the Goss texture decreases by 82%. The texture intensity of { 111} 〈112〉 in the single cold rolled plates decreases with the increase of slab heating temperatures and the texture intensity of{ 111} 〈112〉 decreases by 58% when the slab heating temperature increases from 1170 ℃ to 1220 ℃.
