以CSP流程生产的稀土低碳钢板为试验材料,进行了不同加热速度下退火模拟试验,并结合光学显微镜和X射线衍射仪,分析了加热速度对退火试样织构和再结晶进程的影响。结果表明,加热速度从29℃/h提高到42℃/h再结晶开始温度提高了40℃,当加热速度提高到80℃/h,再结晶开始温度670℃;退火后形成了以{223}<110>和{111}<110>为主的再结晶织构,提高加热速度,α取向线上的{001}<110>和{111}<110>织构密度增强,{112}<110>、{223}<110>和{111}<110>均降低;γ取向线{111}<112>和{111}<110>织构密度以及密度差均降低。
The rare earth low carbon steel plate produced by CSP process was used as the experimental material, and the simulated annealing experiments at different heating rates were carried out. The effects of heating rate on the microstructure and recrystallization of annealed samples were analyzed with optical microscope and X-ray diffraction. The results showed that the heating rate increased from 29 ℃ / h to 42 ℃ / h and the recrystallization temperature increased by 40 ℃. When the heating rate increased to 80 ℃ / h and the recrystallization start temperature was 670 ℃, <110> and {111} <110>, the texture of {001} <110> and {111} <110> on the α orientation line is enhanced and the {112} <110 >, {223} <110> and {111} <110>, respectively. Both the density and density of γ-orientation lines {111} <112> and {111} <110> decreased.
