摘　　要：通过对Pb-Ca-Sn-Al合金腐蚀速率检测、导电性能测试、金相组织检验、拉伸性能测试等方面研究轧制工艺对蓄电池板栅性能的影响。结果表明:随着轧制工艺的变化,腐蚀速率由3.5836 g·m-2.h-1降低到3.1954 g·m-2.h-1,显著提高了蓄电池的使用寿命;IACS导电率值由7.9196升高到7.9708,可以降低蓄电池在使用过程中的电能损耗,节约资源;金相组织主要为α固溶体相和少量球状Pb3Ca化合物,随着轧制工艺的变化晶粒逐渐变大;抗拉强度由50 MPa降低到40 MPa,延伸率由7%提高到9.5%,延伸率高,拉网过程中不容易产生裂纹和断裂,提高了成材率和生产效率。The influences of rolling process on the mechanical properties of grids of lead-acid batteries were studied through the corrosion rate test, conductive performance test, metallographic structure examination and tensile properties test. The results showed that as the rolling process was changed, the corrosion rate was reduced from 3.5836 g.m2.h-~ to 3.1954 g-m-2.h-~ which could obviously improve the service life of battery, and the conductive rate was improved from 7.9196 to 7.9708 which could reduce the electricity waste and save the resource. The metallographic structure mainly included c~ -solid solution phase and small amount of spherical Pb3Ca compounds. The grain size became larger with the changed rolling process. The tensile strength was reduced from 50 MPa to 40 MPa. The elongation was increased from 7 % to 9.5 % which could lessen the cracking and fracture in the expanding grid process, and improve the yield and the production efficiency.
