对应用动态加热进行短时温度退火的取向电工钢进行了二次再结晶研究。所进行研究的实验用取向电工钢是经过终冷轧和后续罩式退火后的一条工业化生产线生产的。研究结果表明,运用短时热处理条件可引起研究钢完全的异常晶粒长大。在实验室处理的材料的织构和金相组织与工业化生产的经过终退火而获得的相同的取向电工钢类似。但是,在实验室处理的取向电工钢的二次再结晶的矩阵中可观测到\"寄生\"晶粒。从磁性观点看,这些\"寄生\"晶粒含有不理想的{111}取向织构。 The present study was made to investigate secondary recrystallization in grain-oriented steels annealed at short time temperature exposures with application of dynamical heating.The investigated GO(Grain Oriented) steels for experiments were taken from one industrial line after final cold rolling reduction and subsequent box annealing.It was shown that application of short time heat treatment conditions could lead to complete abnormal grain growth in the investigated GO steel.The texture and mic...

在实验室试制了TSCR流程的低碳低硅无取向硅钢,研究了在850~1050℃不同温度常化对冷轧量0.5mm厚钢板再经950℃×7min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。 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.

通过热力学计算及实验室研究,对钙处理前后50W600无取向硅钢退火冷轧板中夹杂物的类型、数量及尺寸进行了系统分析。结果表明,50W600无取向硅钢经钙处理后(w(Ca)=0.002 6%),钙在1 600℃的钢液中主要以固态的CaO·2Al2O3、CaO·6Al2O3及溶解钙的形式存在。在钢液的凝固过程中,钢中的溶解钙和硫反应生成了CaS和CaS-MnS复合夹杂,有效抑制了MnS的弥散析出,减少了钢中微细夹杂物的数量。同时钙处理促进了钢中微细夹杂物的聚合长大,导致显微夹杂物的数量增加。 Based on thermodynamic calculation and laboratory experiment,the type,quantity and size of inclusions in annealed cold-rolled steel sheets of 50W600 non-oriented silicon steel before and after calcium treatment were systematically studied.Results showed that after calcium treatment(w(Ca) = 0.002 6%),calcium was mainly in the form of CaO·2Al2O3,CaO·6Al2O3 and dissolved calcium in steel at 1 600 ℃.Dissolved calcium could combine with sulfur to form CaS inclusions and compound CaS-MnS inclusions du...
