采用取向分布函数和取向线分析方法对低温板坯加热取向硅钢从热轧到初次再结晶工艺阶段的织构进行了研究。研究表明:一次冷轧后各层的织构组分与热轧板各层面的织构组分存在着继承关系,次表层存在很强的{001}<110>织构,中心层的织构和热轧板的中心层相似,存在强的{001}<110>和{112}<110>织构;中间退火后发生再结晶,各织构组分的强度有所减弱,Goss织构组分再次出现;二次冷轧后沿厚度方向上的织构不均匀性不明显,{111}<112>织构强度最高,几乎是其他织构组分的1倍,{001}<110>织构大幅降低;初次再结晶后织构沿厚度方向没有明显的不均匀性,{111}<110>为最强的织构组分,并且具有一定强度的Goss位向。 The texture from the first cold rolling to the primary recrystallization of low temperature slab reheating grain-oriented electrical steel were researched by orientation distribution function and orientation distribution intensity technique.The results show that after the first stage of cold rolling,there is a strong {001}<110> texture in the subsurface and the texture in center layer is very similar to the center layer of hot band which has strong {001}<110> and {112}<110> tex...

研究了铝和铬元素在无取向电工钢晶粒长大过程中对织构及晶界变化的影响规律。试验结果表明:电工钢在晶粒长大过程中的主要织构组分均为{111}<112>。在晶粒生长期间,不加铝的1号试样中,{111}<112>、{111}<110>织构组分强化,而{100}<001>织构组分弱化;与1号试样相比,在加入0.2%的铝(质量分数,下同)的2号试样中,{111}<112>、{111}<110>织构组分强化(增加)的速率下降,{100}<001>织构组分变化不明显,甚至稍有增加。在含铝的试样中再加入0.3 5%的铬之后(3号试样),{111}<112>{、111}<110>和{100}<001>织构组分的变化规律与1号试样相似,但当电工钢中加入0.72%的铬之后(4号试样),上述3种织构组分的变化规律与2号试样相似。对于在晶粒生长期间持续变化的3种织构组分而言,1号试样的{1 1 1}<112>和{111}<110>织构组分的高(低)取向差角度晶界频率下降(... The effect rule of Aluminm and Chromium on texture and grain boundary transformation in the nonoriented electrical steel during grain growth was investigated.The experimental result shows that the main texture component is {111}<112> in the electrical steel.The {111}<112> and {111}<110> components in specimen 1 without Alumium were strengthened during grain growth whereas {100}<001> component was weakened.But the growth rate of {111}<112> and {111}<110> compon...

为了解决目前冷轧产线硅钢现有切边技术存在的微裂纹、应力、毛刺和边浪等问题,采用光纤激光器进行了高速切割实验,对激光功率、切割速度、激光模式等影响因素进行了分析,同时对高速切割时的切割前沿形状进行了研究。结果表明,切割最高速度随着功率的增加而增加;随着离焦量的增加,切割质量下降,挂渣增多,切缝宽度增加,切割深度变浅;基模激光器能量密度更高,所以薄板切割时的切割速度高于多模激光器;切割前沿随着切割速度的增加会变得平缓,速度足够大时,切割前沿甚至接近与切割方向平行,此时切缝下部存在挂渣现象。 In order to solve the problems such as micro crack,stress,burr,edge waves and so on,existing in cold rolling production line of silicon steel side cutting,experimentsof high speed laser cutting using fiber laser were carried out.Laser power,cutting speed,laser mode and other factors were analyzed,at the same time,cutting front geometries were studied.The results show that the maximum speed increases with power.And the increases of defocus result in poor quality,wider kerf and shallowerkerf.Energ...
