退火温度和时间对冷轧无取向硅钢组织与织构的影响

Influence of Annealing Temperature and Time on Structure and Texture of Cold Rolled Non - oriented Silicon Steel

针对冷轧无取向硅钢退火工艺的特点,研究了退火温度和保温时间对成分为0.004%C、0.33%Si的冷轧无取向硅钢晶粒组织和织构演变的影响。结果表明:退火后,α线上{100}织构密度明显减弱,取向从{112}<1lO>向{111}<112>大量聚集;适当增加保温时间有助于提高{100}<hkl>织构,900℃、保温180 s,水冷得到的织构分布比较均匀,{001}面织构占有率比较高。

Considering the annealing technology of cold rolled non- oriented silicon steel, the effects of annealing temperature and time on structure and texture are investigated. The results show that the density of {100} texture drops obviously in the a line and grains get together from {112} 〈 110 〉 to {111} 〈 112 〉 after annealed. The { 100 } 〈 hkl 〉 texture increases with the proper lasting of incubation time. The texture distributes homogeneous and the occupancy of {001 } texture are improved when the cold rolled non - oriented silicon steel is annealed at 900℃, holding 180 s and then water cooling.
