摘要
研究了同步和异步轧制下无取向硅钢的冷轧织构及其沿层厚的分布特征.不同轧制方式下冷轧织构均主要由以{001}〈110〉为强点的α织构和强度相对较弱的γ织构组成,但异步轧制显著影响冷轧织构强度及其沿层厚的分布.异步轧制对表层和中间层织构强度的影响较1/4层大;异步轧制总体上减少α和γ织构,但增加{111}〈112〉组分.这表明冷轧过程引入异步轧制可为无取向硅钢的织构控制与优化开辟新的途径.
The cold rolling texture distribution along thickness of asymmetrically rolled non-grain oriented （NGO） silicon steel sheet is studied. It is revealed that the cold rolling texture is composed of strong incomplete α （〈110〉//RD） fiber and relatively weak complete γ fiber （〈111〉 //ND） no matter what rolling schedule is taken on, but asymmetric rolling affects greatly the textural strength and its distribution along thickness. Asymmetric rolling has a greater effect on textural strength of surface and middle layers than on the quarter layer, and it reduces both α and γ fibers with decreasing {111}〈110〉 component, but the { 111 } 〈112〉 component increases .somewhat. Thus, the application of asymmetric rolling to cold rolling process can provide a new approach to control and optimize the texture of high-grade NGO silicon steel sheet.
