摘　　要：对含铜取向硅钢一次冷轧板在840℃下进行不同时间(1~13 min)的脱碳退火处理,探究退火时间对取向硅钢C、O含量、初次再结晶晶粒、氧化层和织构的影响。结果表明,随脱碳退火时间的增加,O含量逐渐增加,C含量先降低后保持不变。由于一次冷轧过程中板厚方向受力不均匀,导致钢板再结晶晶粒尺寸不均匀,随脱碳退火时间增加,不均匀性变得更加明显。随脱碳退火时间增加,氧化层厚度增加,旋转立方织构{001}<110>和立方织构{001}<100>占比逐渐降低,{111}<112>织构含量先增加后降低,高斯织构{110}<001>占比基本不变。Cold-rolled plate of Cu-bearing grain oriented silicon steel was subjected to decarburization annealing at 84 C for different time(1-13 min).The effect of annealing time on the content of C and O elements,primary recrystallized grains,oxide layer and texture of the grain oriented silicon steel was investigated.The results show that with the increase of decarburization annealing time,the content of O increases gradually,while the content of C decreases first and then remains unchanged.Due to the uneven stress in the thickness direction during the one-stage cold rolling process,the recrystallized grain size of the steel plate is uneven.As the decarburization annealing time increases,the inhomogeneity becomes more obvious.With the increase of decarburization annealing time,the thickness of oxide layer increases,the proportion of rotating cube texture [1001]<110>and cube texture{001}<100>decreases gradually,the content of[111]<112>texture increases first and then decreases,and the proportion of Goss texture[110]<001>is basically unchanged.
