研究了超纯21%Cr铁素体不锈钢精轧温度对织构演变规律和成形性能的影响。将粗轧板坯切块并在900~750℃范围内进行精轧,随后经相同的热轧退火、酸洗、冷轧及退火处理,系统研究了试样的宏观织构、显微织构和成形性能的变化规律。结果表明:精轧温度对铁素体不锈钢的织构演变有重要影响,降低热轧精轧温度有利于增加热轧退火板中{111}再结晶织构组分;冷轧及冷轧退火板的织构分布具有明显的遗传性,热轧板中较高的{111}再结晶织构组分,促进了冷轧退火板中{111}再结晶织构的生成,从而提高了铁素体不锈钢的成形性能。 The effect of finish rolling temperature on texture evolution and formability of ultra-pure 21% Cr ferritic stainless steel was studied. The rough slab was cut and rolled in the range of 900 ~ 750 ℃, followed by the same hot-rolled annealing, pickling, cold rolling and annealing treatment, the system of the sample macro-texture, micro-texture And formability of the law of change. The results show that the finishing temperature has an important influence on the texture evolution of ferritic stainless steel. Reducing the finish rolling temperature in hot rolling is favorable for increasing the {111} recrystallization texture components in the hot rolled annealed sheet; cold rolling and cold rolled annealed sheet The texture distribution of the hot rolled sheet is obviously hereditary. The higher {111} recrystallization textures in the hot rolled sheet promote the formation of the {111} recrystallization texture in the cold rolled annealed sheet, thereby increasing the ferrite Stainless steel forming performance.
