以不断增长的薄板坯流程为背景,与传统流程对比分析了薄板坯流程无取向电工钢热轧晶粒组织特征;以50W800和50W1300钢为典型实例,探讨了两种流程下成品板晶粒组织、织构、磁性能及其磁时效行为的基体差异和相关原理。研究表明,薄板坯流程热轧板组织较粗大,有利于在成品板中获得粗大的晶粒和有利的织构,从而得到较低的铁损和较高的磁感。然而,薄板坯流程会造成第二相粒子的细小弥散分布与不充分析出,容易因磁时效而使磁性能恶化。 Based on the rapid development of compact strip production(CSP) processing,the characteristics of hot band grain structure produced by CSP processing were analyzed in comparison with those of conventional technology.The basic differences in grain size,texture,magnetic properties and the magnetic aging behaviors of the final sheet products produced by the two processing technologies and the corresponding principles were discussed,while steel 50W800 and 50W1300 were taken as examples.It is indicat...

本发明提供一种超低铝无取向硅钢夹杂物控制方法。该钢种化学成分质量百分比为C≤0.005%,Si:0.25%‑1.50%,Mn:0.15%‑0.55%,P:0.02%‑0.06%,S≤0.005%,Als≤0.005%,余量为Fe及不可避免的杂质。工艺流程为:KR→BOF→RH→连铸。转炉出钢严格控制下渣量,出钢结束加石灰、渣面脱氧剂调渣;RH脱碳结束后,先加低碳低硫硅铁、金属铝或铝钙铁合金复合脱氧,最后加入金属锰、磷铁进行合金化,然后净循环6‑10min,破空出钢运至连铸浇注。得到钢水中主要为SiO2‑Al2O3系夹杂,避免了生成低熔点SiO2‑MnO系夹杂,轧制延展变长,影响晶粒长大;同时也避免了生成高SiO2组分类酸性夹杂,导致耐材的侵蚀。可显著改善钢中非金属夹杂物类型,提高无取向硅钢的性能,并提高了钢水浇注性能。

本发明提供一种优化无取向硅钢连续退火工艺的铁损预测方法,步骤包括:S1.建立预测模型回归方程表达式;S2.将无取向硅钢中的硅、锰、铝质量含量及预设的退火速度、退火温度代入S1中的回归方程表达式中进行计算;S3.将步骤S2计算得到的预测值与目标值进行比较,如果预测值在目标值的允许误差范围内,则按照预设的退火速度、退火温度进行生产;否则对预设的退火速度、退火温度进行调整,直至预测值能够达到目标值的要求后再进行生产。本发明提供的模型能够提高产品质量,对优化无取向硅钢连续退火工艺具有指导意义。
