取向硅钢27Q110初次再结晶退火对组织和织构的影响

Effect of Primary Recrystallization Annealing on Structure and Texture of Oriented Silicon Steel 27Q110

通过检测取向硅钢27Q110一次冷轧板再结晶温度退火试验后的硬度及显微组织,确定取向硅钢脱碳退火(初次再结晶)阶段最佳退火温度为850℃。对冷轧硅钢厂取向硅钢27Q110脱碳退火后显微组织和织构进行检测和分析。结果表明,取向硅钢27Q110脱碳最佳退火温度为850℃,且主要织构γ在{111}<112>处最强。

Based on the hardness and microstructure of the primary cold-rolled sheet of oriented silicon steel 27Q110 recrystallization temperature annealing test,the optimal annealing temperature of decarburization annealing(primary recrystallization)of oriented silicon is determined to be 850 ℃.The microstructure and texture of the oriented silicon steel 27Q110 produced at cold rolling works after decarburization annealing are detected and analyzed.The results show that the optimum annealing temperature of decarburization of oriected silicon steel 27Q110 is 850℃,and the main γ texture is the strongest at {111}<112>.
