要加速钢质易开盖取代铝质易开盖的进程,首先必须用提高材料强度以减薄钢板厚度的方法改善罐头的开启性能。材料的研制着眼于钢质罐盖的可铆接性以及罐头的可开启性(特别是爆裂值)伴随强度的提高而得到弥补。我们通过试验研究,已经获得关于具有细微渗碳体的高含碳量钢是解决这个问题的有效方法的资料。 To speed up the process of replacing steel with easy-open steel with an easy-open lid, the openability of cans must first be improved by increasing the strength of the material to reduce the thickness of the steel. Development of materials Focusing on the riveting properties of steel can lids and the openability of the cans (particularly the burst value) are compensated by the increased strength. Through experimental studies, we have obtained data on effective methods for solving this problem with high carbon steels with fine cementite.
