摘要: 试验研究了0.3 mm取向硅钢冷轧板(/%:0.046C,3.07Si,0.09Mn,0.029P,0.004S,0.005Al)的退火温度(760~880℃7 min)和退火时间(820℃3~9 min)对该钢的晶粒尺寸,再结晶和织构的影响。结果表明,最佳初次再结晶退火工艺为820℃5 min,该钢的平均晶粒尺寸为14.20μm,完全再结晶率为92%,不利{111}<110>结构含量为3.16%,有利织构{111}<112>,{012}<001>和高斯织构含量分别0.40%,4.73%和2.46%。

Abstract: The effect of annealing temperature (at 760 ~ 880 ℃ for 7 min) and time (at 820 ℃ for 3 ~ 9 min) on grain size, recrystallization rate and texture of 0. 3 mm cold-rolled sheet of oriented silicon steel (/% : 0. 046C, 3.07Si, 0. 09Mn, 0. 029P, 0. 004S, 0. 005Al) has been tested and studied. Results show that with optimum recrystallized annealing at 820 ℃ for 5 min, the silicon steel average grain size is 14. 20 the complete recrystallization rate is 92%, the unfavourable-texture {111} < 110 > content in steel is 3.16%, the favourable-texture {111} < 112 >, {012}<001 > and Gauss texture content in steel are respectively 0.40%, 4.73% and 2.46%.
