Effect of Normalizing Temperature on Microstructure and Properties of Low-Carbon and Low-Silicon Non-oriented Silicon Steel Prepared by TSCR Process
摘 要
在实验室试制了TSCR流程的低碳低硅无取向硅钢, 研究了在850~1 050 ℃不同温度常化对冷轧量0.5 mm厚钢板再经950 ℃×7 min退火后的组织、织构和磁性能的影响。结果表明: 随常化温度的升高, 使热轧板晶粒尺寸增大, 晶界更清晰, 组织均匀性更好; 由于第二相AlN和MnS析出物尺寸比较大, 使冷轧退火后钢板晶粒也随常化温度升高呈单调增大趋势; γ有利织构和{111}、{112}不利织构与常化温度升高同时增强, 但前者增强更多; 冷轧板退火后铁损随常化温度升高呈单调下降, 磁感呈单调上升趋势。
Abstract
The low-carbon and low-silicon non-oriented silicon steel was prepared by thin slab casting and rolling (TSCR) in lab. The effect of normalizing at different temperatures in 850-1 050 ℃ on microstructure, texture and magnetic properties of 0.5 mm cold-rolled sheets after annealing at 950 ℃ for 7 min was researched. The results show that with increasing the normalizing temperature, the grain size of hot-rolled sheets increased, the grain boundaries were more clear and the microstructure uniformity was better. The grain size of cold-rolled sheets after annealing monotonely increased with increasing the normalizing tempereture for the second phase precipitates of AlN and MnS were too large. The favorable texture of γ and unfavorable texture of {111} and {112} stengthened simultaneously with increasing the normalizing temperature, while the former was more obvious. The iron loss of the steel after annealing showed monotone decreasing with the increase of normalizing temperature, and the magnetic induction showed monotone increasing.
