| 摘 要： | 3%Si钢(/%:0.067C、3.09Si、0.34Mn、0.007P、0.003S、0.70Cu、≤0.005Al、0.0080～0.0120N)由50kg真空感应炉冶炼,并在实验室轧机经6道次热轧成3.5mm板,终轧温度850℃,卷取温度650℃,热轧板经常化处理后由4辊可逆轧机6道次冷轧成0.50mm薄板。分析结果表明,热轧板表面主要为随机分布较大的等轴晶,中心处由细小等轴晶和长条状晶粒组成,并出现了很强的旋转立方织构{001}〈110〉。经过冷轧,薄板表面出现了很强的α织构和γ织构组分,并且冷轧板保留了热轧的{001}〈110〉旋转立方织构。

| Abstract: | The 3%Si steel(/%:0.067C,3.09Si,0.34Mn,0.007P,0.003S,0.70Cu,≤0.005Al,0.008 0～0.012 ON) is melted by a 50 kg vacuum induction furnace and hot rolled to 3.5mm plate by 6 pass with finishing rolling at 850℃and coiling at 650℃by laboratory mill,then normalized hot rolled plate is cold rolled to 0.5 mm sheet by 4 roll reversing mill with 6 passes.Analysis results show that at surface region of hot rolled plate there are mainly random distributed larger equiaxial grains,the center area consists of fine equiaxial grains and lath shape grains and the strong rotating cube texture | 001 |〈110〉components occur in center area;After cold rolling,the strongαandγtextures occur at surface region and the hot rolled |001 |〈110〉rotating cube textures are retained in cold rolled sheet. |
