| 摘 要： | 采用唐山钢铁股份有限公司FTSR连铸连轧生产线生产的热轧卷作为生产冷轧低碳钢板的原料，研究了不同卷取温度和冷轧压下率对冷轧薄板深冲性能的影响。结果表明，采用低温卷取有利于提高钢板的深冲性能。以3．5mm厚和2．5mm厚热轧板为原料的冷轧低碳钢板的r值分别在冷轧压下率为70．2％和71．3％时出现峰值。生产厚度大于等于0．8mm的低碳钢板时应采用3．5mm厚的热轧卷，生产厚度小于0．8mm的冷轧板时应采用2．5mm厚的热轧卷。 |
| 关 键 词： | 卷取温度 冷轧压下率 深冲性能 织构 冷连轧 |

| Abstract: | The effects of coiling temperature and cold rolling reduction ratio on deep-drawing properties of lowcarbon sheets hot-rolled by FTSR of Tangsteel were investigated in laboratory. The experiment results show that low coiling temperature can improve the deep-drawing properties. The maximum r values of low-carbon sheets hot-rolled from 3.5ram-thick and 2.5ram-thick strips are achieved respectively at the cold reduction of 70, 2% and 71.3%. 3.5mm-thick strips should be used for the production of low-carbon sheets with thickness no more than 0.8ram and 2.5ram-thick strips for those thinner than 0.8ram. |
| Keywords: | coiling temperature cold rolling reduction ratio deel-drawing property texture cold tandem rolling |
