梅钢平整大延伸实现高硬度等级镀锡板的研究

Research of Meigang Big Elongation Temper Rolling to Achieve High Hardness Grade Tinplate

在试验室模拟了连续退火生产镀锡板MR T-4CA不同延伸率的平整,研究平整延伸率对连续退火生产MR T-4CA镀锡板力学性能影响关系,比较了仅通过增加平整量生产的高硬度级别镀锡板与二次冷轧产品的差异性,并评估了梅钢连退平整机大延伸率轧制的负荷能力,提出了通过平整大延伸实现高硬度级别镀锡板的建议,为工业应用提供参考。

In this paper, Simulated the continuous annealing production of tinplate MR T-4CA dif- ferent temper roiling elongation in the laboratory, Researched the relationship between elongation and the mechanical properties of continuous annealing production MR T-4CA tinplate, Compared the high hardness level tinplate only by increasing temper rolling elongation and two cold-rolled products, And evaluated load capacity of MeiGang continuous annealing temper mill under big e- longation,Proposed the Suggestions of realizing the high hardness level tinplate by big elongation Temper rolling,Provide a reference for industrial application.
