摘　　要：在节能减排的背景之下,水电、风电和核电等清洁能源行业得到了快速发展。高牌号无取向硅钢是上述发电机组应用最普遍的铁芯材料。因此,开发低铁损和高磁感的高牌号无取向硅钢是清洁能源产业高质量发展的前提条件。织构是影响高牌号无取向硅钢磁感和铁损的主要因素之一,受到生产工艺的影响。然而,高牌号无取向硅钢工艺流程长,影响织构控制的工艺因素众多。为了满足高牌号无取向硅钢在低铁损时实现高磁感,在产品加工时应尽量避免对磁性能不利的{111}织构的形成,促进对其有利的{100}和{110}织构形成。本文首先介绍了高牌号无取向硅钢的工艺流程,对比了国内外钢铁企业产品的磁性能(P_(15/50)和B_(50))。其次,阐述了高牌号无取向硅钢在炼钢、热轧、常化、冷轧和成品退火过程中促进有利织构形成的影响因素。最后,归纳出能促进高牌号无取向硅钢有利织构形成的生产工艺,并对织构控制的发展方向提出了建议。Recently,against the background of energy conservation and emission reduction,the use of clean energy produced by hydropower,wind power and nuclear power has been increasing rapidly,and high grade non-oriented silicon steel is the most widely used core material for the aforementioned energy generation methods.Therefore,the development of high grade non-oriented silicon steel with low iron loss and high magnetic induction is a prerequisite for high-quality developments of the clean-energy industry.Generally,the magnetic induction and iron loss of high grade non-oriented silicon steel are affected by texture,which is influenced by the manufacturing process;however,the process flow of high grade non-oriented silicon steel is long,and hence,texture control is typically affected by numerous process factors.Thus,to achieve high magnetic induction of high grade non-oriented silicon steel with low iron loss,it is necessary to avoid{111}textures that are unfavourable to the magnetic properties while promoting the{100}and{110}textures that are favourable to the magnetic properties during production.First,this paper introduces the process flow of high grade non-oriented silicon steel and compares the magnetic properties(P_(15/50)and B_(50))of products obtained from steel corporations worldwide.Second,factors influencing the promotion of favourable texture formation for high grade non-oriented silicon steel during steelmaking,hot rolling,normalisation,cold rolling and final annealing are elaborated.Finally,the manufacturing processes favourable for the texture improvement of high grade non-oriented silicon steel are summarised,and suggestions for the development of texture control strategies are put forth.
