选用不同硅含量的工业用无取向硅钢热轧板作为研究对象，采用X射线衍射Schulz背反射法对热轧板进行了分层织构测量。结果表明，高硅热轧板表层织构以（1-10）［００１］为主，并有少量(3-31)［55-3］，板中心部位以(001)［11-0］为主；低硅热轧板表层含有少量的(1-10)［1-1-1］、(1-10)［2-2-1］和(5-51)［111-］，而板中心部位主要为(001)［11-0］织构，但强度比高硅热轧板低；织构沿厚度方向的分布具有一定的规律性，即表层附近织构以(1-10)［001］为主，中心处织构以(001)［11-0］为主，只是强度有差异；热轧温度变化时，织构的强弱有明显的变化，热轧温度对不同硅含量热轧板织构的影响是不同的。
The stratified texture measurement on industrial nonoriented hotrolled electric steel with various silicon content was conducted by using Xray diffractionSchulz backside reflection. The results show that the texture of top layer of hotrolled higher silicon electrical steel sheet is dominated by (1-10)［001］ with trace (3-31)［55-3］ texture and in the center there is mainly(001)［11-0］.There is small amount of (1-10)［1-1-1］、(1-10)［2-2-1］ and (5-51)［111-］ texture is the top layer of hotrolled low silicon electrical steel sheet, while the center is mainly (001)［11-0］, but the intensity is lower than that of high silicon electric steel.Thus The texture distribution in the thickness direction for both high and low silicon electrical steel sheets follows some pattern, ie.,in the top layer there is mainly (110)［001］ and in the center there is mainly (001)［11-0］, but the intensity is different. There is a significant change of texture intensity with the temperature change of hot rolling. The effect of hot rolling temperature on texture of hotrolled electric steel with different silicon content is different.
