摘要
本文重点研究一种频率较高的极薄取向硅钢材料,它的厚度在0.10(0.08)、0.05、0.03 mm,宽度350 mm以下,频率在400~3000 Hz,其产品主要来源于进口.近年来,个别企业开发出一种无底层HiB取向硅钢原材料,并投放市场使用,取得了明显效果.研究表明无底层HiB取向硅钢原材料的出现,改变了前期的生产工艺,重点解决了去除表面涂层及玻璃膜底层的"瓶颈"问题,减少了一道工序,它为稳定生产极薄取向硅钢,实现国产化,减少进口,奠定了重要基础.
This paper focuses on a kind of extremely thin oriented electrical steel with high frequency,whose thickness is 0.10 mm(0.08 mm),0.05 mm,0.03 mm,width is below 350 mm,and the frequency is between 400 and 3000 Hz.The product is mainly imported.In recent years,some enterprises have developed a kind of raw material of HiB oriented electrical steel without the glass film,and put it into use,which achieved obvious effect.The research shows that the appearance of the raw material of HiB oriented electrical steel without glass film changes the previous production process,mainly solves the problem of"bottle-neck"of removing surface coating and bottom layer of glass film,and reduces a working procedure.It lays an important foundation for stable production of extremely thin oriented electrical steel to realize localization and reduce import.
