摘　　要：本文采用单辊快速凝固技术制备出Fe-6.5%Si的高硅钢薄带,研究了冷却速度对快凝薄带的显微组织及织构变化的影响,并对不同辊速的板带组织晶粒尺寸进行计算。结果表明,不同辊速下制备的快凝带均形成了近{100}织构,且在凝固过程中,温度梯度方向偏离了薄带法向,形成了{116}织构。In this paper,author use the single-roll rapid solidification method to manufacture steel strip.Fe-6.5%Si ribbons organization and microstructure with different cooling rates were studied.The formula of theaverage grain size along with roller speed is summed up.Preparation of the various roller-speed fast condensateare formed with nearly(100)texture,and in the process of coagulation,with the roll of the rotation,thetemperature gradient has deviated from the direction of the strip,formed a(116)texture.
