对深冲用带材提出了在某种程度上看来是互相对立的各种要求。在轧制平面内要有各向同性,同时又要有能保证所要求的延伸系数的高塑性。此外,用带材生产的某些制品要求有较高的强度。属于这一类的产品有压制的铝包装容器,其产量日益增加。带材生产流程包括:热轧到3～6毫米;冷轧成最终尺寸,有中间退火或无中间退火;最终退火。退火(中间退火和最终退火)可以在分批装料退火炉或连续退火炉内进行。后一种情况是利用特殊的气垫式退火炉,退火与带材漆层的干燥同时进行。本文研究了最终冷变形程度及中间和最终退火制度对强度性能和塑性的各向异性的影响,以及确定了可以得到上述性能最佳结合的方案。
The requirements for deep drawing tape appear to be somewhat antagonistic to one another. In the rolling plane must have isotropy, but also have to ensure that the required elongation coefficient of high ductility. In addition, some articles produced from tape require higher strength. Products falling into this category have pressed aluminum containers and their output is increasing. Strip production process includes: hot-rolled to 3 to 6 mm; cold-rolled into the final size, with or without intermediate annealing intermediate annealing; final annealing. Annealing (intermediate annealing and final annealing) can be carried out in a batch charge annealing furnace or a continuous annealing furnace. The latter case is the use of a special air-cushion annealing furnace, annealing and strip paint drying at the same time. In this paper, the effect of the final cold deformation and the intermediate and final annealing regimes on the anisotropy of strength and ductility were studied, and the optimum combination of these properties was determined.
