Abstract: The effect of product thickness (0.35 ~0.65 mm) of sheet on texture, magnetic induction and core less of 0. 003% C-2.40% Si-0.32% Al non-oriented silicon steel sheet have been studied. Results showed that with decreasing the thickness of sheet, the component of unfavorable texture in products to magnetic properties increased, the component of favorable texture decreased led to decreasing magnetic induction； in conditions of definite chemical composition and grain size of steel, the major factor to influence core loss was thickness of steel sheet, as the thickness decreased from 0.65 mm to 0.35 mm, the core loss decreased obviously.

Key words: Non-Oriented Silicon Steel, Product Thickness, Cold Rolling Reduction Ratio, Texture, Magnetic Properties

摘要： 研究了成品板厚度(0.35～0.65 mm)对0.003%C-2.40%Si-0.32%Al无取向硅钢织构演变、磁感和铁损的影响。结果表明,随着钢板厚度的减薄,成品中对磁性不利的织构组分增加,有利织构组分减少,磁感降低。在化学成分和晶粒尺寸一定的情况下,影响铁损的主要因素是钢板厚度,钢板厚度从0.65 mm减薄至0.35 mm时,铁损显著降低。
