本发明涉及一种硅钢片铁芯用自动叠装系统,托板、上料单元、精定位单元、叠装单元、抓取单元,所述上料单元有一个,位于中部位置,所述精定位单元一共有两个,分别位于上料单元的两侧,所述叠装单元一共有两个,分别位于两个精定位单元的两侧,从而使得整个自动叠装系统由中间向两侧方向均依次为上料单元、精定位单元、叠装单元。本发明的优点在于:通过对上料单元、精定位单元、叠装单元的数量及排布位置进行重新设计,采用由中间向两侧供料的方式,使得两侧的上料顺序均独立运行,不存在相互干涉的风险,确保单侧的上料顺序的顺利进行,相对应的也就降低了程序设计的复杂程度,减轻了设计人员的工作强度。

通过对取向硅钢进行脉冲磁场退火实验,发现在相同的退火时间(6.0 min)内,低于1 T的脉冲磁场可以在一定程度上提高取向硅钢的磁感(B8),而高于1 T的脉冲磁场则会使取向硅钢的磁性能急剧恶化.同时发现,脉冲直流电加热方式会使取向硅钢的磁性能恶化.研究表明,脉冲磁场退火有望成为一种调控材料微观结构的有效手段. We have carried out experiments of annealing by pulse magnetic field.The results show that a pulse magnetic field with intensity lower than 1 T can promote magnetic induction density(B8) of grain-oriented silicon steel,while the magnetic properties deteriorate sharply when intensity is higher than 1 T.It has also been found that heating by using pulse direct current can cause the magnetic properties to deteriorate,in contrast to the traditional heating using resistance furnace.Our research shows...

含铜抑制剂作为取向硅钢的主抑制剂或辅助抑制剂不仅可以抑制初次晶粒的长大,促进二次再结晶,还可以降低铸坯的加热温度。取向硅钢中主要抑制剂为10~50 nm Cu2S,在钢的铸坯、热轧、冷轧、脱碳等工艺过程均可析出;(Cu,Mn)1.8S、Cu1.8S、ε-Cu等主要作为辅助抑制剂,尺寸一般为30~50 nm(或大于50 nm),主要在热轧阶段析出。总结了国内外有关取向硅钢中含铜抑制剂析出行为的研究进展,当前主要研究不同生产流程和工序中含铜抑制剂的析出行为和作用机理。 As main inhibitor or auxiliary inhibitor for grain-oriented silicon steel,the particles of inhibitor bearing copper not only inhibit the primary crystal growing and promote the secondary recrystallization,but also decrease the heat temperature of casting slab.The main inhibitor for grain-oriented silicon steel is 10~50 nm Cu2S,which precipitate in process and procedure including steel casting slab,hot rolling,cold rolling and decarburizing process,while the 30~50 nm or more than 50 nm...

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.
