结合工业化生产的无取向硅钢,探讨了氧硫交互作用对钢中夹杂物生成的影响。借助非水溶液电解+扫描电镜法,研究了不同O、S含量下钢中夹杂物的变化规律。结果表明,本实验条件下,提高O含量、降低S含量,会劣化热轧组织再结晶效果。在劣化效果上,O的作用大于S;低Si、无Al硅钢中,应尽可能降低O含量、适当提高S含量,以粗化钢中微细夹杂物,减少尺寸小于1.0μm的夹杂物的数量;O、S含量与钢中夹杂物数量不具有关联性。生产过程中,不仅要严格控制O、S含量,还要严格控制生产工艺,以免生成较多的有害夹杂物。 Based on the industrial production of non-oriented silicon steel,the effects of interaction between oxygen and sulfur on the formation of inclusions were discussed.The change of non-metallic inclusions in steel sheets was investigated by means of electrolysis with non-aqueous solution under different oxygen and sulfur content.Results show that the recrystallization microstructure of hot rolled sheets will be deteriorated with the increase of oxygen content and the decrease of sulfur content.The ...

运用电子背散射衍射(EBSD)技术,研究了50W600无取向硅钢在热轧→冷轧→退火工序间织构的演变。结果表明:由于热轧板沿板厚方向的应力场和温度场存在差异,导致热轧板不同层织构类型和强度存在差异;热轧板表层主要存在铜型、黄铜和高斯织构,1/4层织构主要为α纤维织构和较弱的高斯织构,中心层织构较单一,主要为α纤维织构;和热轧板相比,冷轧板各层织构差异较小,为典型的轧制织构(α纤维织构和γ纤维织构);退火板各层都表现为γ纤维织构增强、α纤维织构减弱,旋转立方织构基本消失。 The texture evolution of 50W600non-oriented silicon steel in hot rolling,cold rolling and annealing process was investigated by electron back-scatter diffraction(EBSD)technology.Results show that the hot rolled plate texture types and intensities along thickness direction were different because of the different stress fields and temperature fields.The major texture types in the surface of hot rolled plate were copper,brass and Gauss texture.The texture was composed ofαfibre texture and weaker Ga... 

采用EBSD技术研究了有、无拉应力作用下无取向硅钢在晶粒长大过程中织构转变及晶界变化的规律。结果表明:在晶粒生长期间,无应力作用下的硅钢中,{111}〈112〉,{111}〈110〉织构组分强化,而{100}〈001〉织构组分弱化;与无拉应力作用下的情况相比,施加5MPa的拉应力时,{111}〈112〉,{111}〈110〉织构组分强化的速率下降,{100}〈001〉织构组分变化不明显。对于在晶粒生长期间持续变化的{111}〈112〉,{111}〈110〉和{100}〈001〉织构组分而言,虽然有、无拉应力作用下硅钢的{111}〈112〉和{111}〈110〉织构组分的高取向差角度晶界频率均下降,而{100}〈001〉织构组分的高取向差角度晶界频率则上升,但当有拉应力作用后,{111}〈112〉和{111}〈110〉织构组分的高取向差角度晶界频率下降的速率变小,{100}〈001〉织构组分的高取向差角度晶界频率上升的速率稍有变小。通过对无取向硅钢在晶粒长大过程中织构转变及晶界变化规律的研究,分析了合金原子在晶界的偏聚行为。 The rules of texture and grain boundary transformation in the nonoriented silicon steel under applied stress or without applied stress during grain growth were investigated by EBSD.The results show that the {111}〈112〉 and {111}〈110〉 components in the nonoriented silicon steel without stress are strengthened during grain growth whereas {100}〈001〉 component is weakened,but the growth rate of {111}〈112〉 and {111}〈110〉 component decreases,while the area fraction of {100}〈001〉 component doesn’t chang...
