摘　　要：采用连铸连轧工艺成功制备了Pb-Ca-Sn-Al合金的蓄电池板栅,通过光学显微观察、力学性能实验、腐蚀实验和电导率实验对不同浇铸温度、轧制温度、冷却方式及轧制变形量的蓄电池板栅Pb-Ca-Sn-Al合金的金相组织及其性能进行研究。结果表明:采用480℃浇注温度、93℃轧制温度、水喷淋冷却方式生产的Pb-Ca-Sn-Al合金厚板带的力学与导电等综合性能最优,通过五道变形量为20%的轧制后,Pb-Ca-Sn-Al合金板带的抗拉强度σb与屈服强度σp0.2分别提高了40.3%和61.5%,抗腐蚀性能是轧制一道的1.69倍。Where prepared by continuous casting and rolling process of Pb-Ca-Sn-A1 alloy bat- tery plate grid, through optical microscopic observation, mechanical performance test, corrosion test and conductivity test for different pouring temperature, rolling temperature, cooling method and rolling deformatinn of the battery plate gate Pb-Ca-Sn-A1 alloy micostructure and its per- formance were studied. The results show that the rolling temperature of 93 ℃ ,pouring temper- ature of 480 ℃ ,water spray cooling way production of Pb-Ca-Sn-A1 alloy thick plate with con- ducting comprehensive performance such as mechanics and optimal, through five deformation after rolling,with 20% Pb-Ca-Sn-A1 alloy plate with the tensile strength ob and yield strength ap0.2 increased by 40.3% and 61.5% respectively,and 1.69 times of corrosion resistance is roll- ing along.
