超薄食品级DR材镀锡板生产工艺研究
|
摘要
退火工艺及二次冷轧工艺是生产超薄规格食品级DR材镀锡板的关键控制技术。通过试验对比分析了不同一轧厚度、不同退火目标硬度和不同二次冷轧压下率工艺条件下所得产品的性能指标。认为采用了T3(57HR3OT)硬度退火工艺+26. 20%二次冷轧压下率工艺模式生产0. 14 mm厚的DR9类产品,生产难度小、成本低。同时研究确定了780℃+220 mm/min为生产该类产品的最佳连退工艺。
Annealing process and secondary cold rolling process are the key control technologies for the production of ultra-thin food grade DR tinplate. The property indexes under different rolling thickness,annealing target hardness and secondary cold rolling reduction rate were compared and analyzed through experiments.It is considered that if the DR9 products,with 0. 14 mm thickness,are produced by T3( 57HR3OT)hardness annealing process plus secondary cold rolling reduction process 26. 20%,both of the production difficulty and cost will be lower. At the same time,780 ℃ + 220 mm/min was determined as the best continuous regression process for such products.
