| Abstract: |
| Two double cold reduction-drawn and redrawn (DRD) tinplate steels of the same chemistries that have been processed by continuous and batch annealing line have been researched. The composition of fibers were studied through X-ray diffraction. The results indicate that a strong intensity of {114}<110> was formed in the continuous annealing steel and a strong intensity of {111}<112> was formed in the batch annealing steel; not only that but the γ fiber slowly rotated to the low angel α fiber with the angel being about 30° nearly {112}<110>texture owing to the higher second reduction. |

| 罩退与连退不同退火方式对制耳特性影响的系统研究 郑晓飞1,2，晏燕1，康永林1 （1. 北京科技大学 材料科学与工程学院, 北京 100083； 2. 首钢京唐钢铁联合有限责任公司, 河北 唐山 063200） 创新点说明：冲压用二次压下材，目前国际同行研究较少，但是随着食品罐减薄趋势的推进，冲压用DR才得到广泛的应用，目前生产DR材的工艺主要有连退和罩退，本文通过研究两种不同工艺下，材料的固溶碳含量以及织构分布情况，得出罩退工艺下更容易得到{114}<110>织构以及{111}<112>，不同工艺下固溶碳含量可以影响织构的形成，经过两种工艺后通过二次压下提高材料的硬度，随着压下量的增加γ织构会缓慢的转向低角度方向，接近指向30°方向的{112}<110>织构，进而提高产品的冲压性能及制耳特性，压下量达到25%时性能最优。 关键词：制耳特性，退火方式，织构，冲压用二次压下材 |
