摘　　要：研究了快速凝固单辊甩带过程中喷嘴尺寸(Φ2 mm、Φ1.5 mm、Φ1 mm和Φ0.7 mm)对Fe-6.5%Si高硅钢薄带组织和性能的影响。结果表明,随着喷嘴尺寸的减少,有序相减少,薄带的连续长度明显提高,而薄带的厚度和宽度减小,晶粒尺寸减小,显微硬度也随之减小。薄带饱和磁化强度(M s)随着喷嘴尺寸的减小逐渐变小,而矫顽力(H c)逐渐变大,但磁性能总体变化不大。在Φ1 mm喷嘴下制得的高硅钢薄带质量较好。The effects of nozzle sizes(Φ2 mm,Φ1.5 mm,Φ1 mm andΦ0.7 mm)on the microstructure and properties of Fe-6.5%Si high silicon steel ribbon during rapid solidification were studied.The results showed that with the decrease of nozzle size,the ordered phase decreases,the continuous length of ribbon increase obviously,but the thickness and width of ribbon decrease,the grain size decreases,and the microhardness decreases.The saturation magnetization(M s)of ribbon decreases gradually with the decrease of nozzle size,and the coercivity(H c)increases gradually,but the magnetic properties do not change much overall.The quality of the high silicon steel ribbon made under theΦ1mm nozzle is better.
