退火温度对双辊连铸无取向硅钢组织的影响
利用光学显微镜、TEM和EBSD研究了退火温度对双辊连铸无取向硅钢再结晶组织的影响。结果表明,900℃退火后组织分布不均匀,有大量带状组织,平均晶粒尺寸29.5μm。提高退火温度,晶粒尺寸增大,组织均匀化程度增加,1050℃退火时,带状组织基本消失,平均晶粒尺寸42.2μm。 Effect of annealing temperature on recrystallization microstructure of non-oriented electrical steel produced by twin-roll casting process was investigated using OM,TEM and EBSD.The results show that the recrystallization microstructure is uneven because of many banded grains existing,average grain size is 29.5 μm.With annealing temperature increasing,the recrystallization grain size increases,microstructure becomes more homogeneous.When 1050 ℃ annealing,the banded structure almost disappear and...
预退火温度对高磁感取向硅钢初次再结晶织构的影响
对高磁感取向硅钢冷轧板分别进行800、950、1050和1120℃不脱碳的预退火处理,在800℃预退火,成品的磁性能较好。织构分析的结果表明,随着预退火温度升高,初次再结晶后有利织构组分{111}<112>与不利织构组分(118)[110]的比值f(111)/f(118)逐渐降低,初次再结晶织构的变化是成品磁性的影响因素之一。 Preliminary annealing process at different temperatures for cold-rolled strips of a high permeability grain-oriented silicon steel was investigated to study the effect of the annealing temperature on microstructure and magnetic performance of the steel.Results show that the magnetic performances of the products annealed at 800 ℃ are best.Analysis of primary recrystallization texture indicates that with rising temperature,f(111)/f(118) which is the ratio of the favorable component {111}<112>...
