摘要电动汽车产业需要大量高品质电池壳钢供应,为了探究目前国内电池壳钢的发展水平,分别选取了不同质量等级的6个厂家电池壳钢轧材,截取10 mm×12 mm 大小的试样,用砂纸由低到高进行打磨,后置于抛光机磨抛,用清水洗净,使用无水乙醇对样品表面喷洗处理以待观察。采用光学金相显微镜(OM)、扫描电子显微镜/能谱(SEM/EDS)、Aspex扫描电镜等表征手段,进行洁净度水平的对比分析,寻找质量差异,为电池壳钢后续品质提升寻找优化方向。研究分析表明:6个厂家样品中,样品3#运用的是低碳铝镇静钢工艺,而其他样品运用的是IF钢的工艺路线。从夹杂物面积占比及尺寸来看,6个厂家中样品6#(夹杂物面积占比最小)、样品3#洁净度最高;样品2#、5#(夹杂物平均直径最大)洁净度最差。在夹杂物类型上,除样品3#中夹杂物以Al₂O₃为主,其他样品夹杂物均主要为Al₂O₃、Ti(C,N)、Ti₄C₂S₂。

Abstract：The supply of many high-quality battery shell steels is required in electric vehicle industry. In order to investigate the current development level of battery shell steel in China, the battery shell steel rolled materials with different quality levels were selected from six manufacturers. The samples were cut into specimens with size of 10 mm×12 mm. After polishing from low to high with sandpaper, the specimens were placed in a polishing machine for polishing followed by washing with water. Finally, the sample surface was cleaned by spraying anhydrous ethanol for characterization. By the means of optical metallographic microscopy (OM), scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and Aspex SEM, the comparative analysis on cleanliness level was conducted to find out the difference in quality, which provided optimization direction for the quality improvement of battery shell steel. It showed that among the samples from six manufacturers, sample 3# applied the low-carbon aluminum sedimentation steel process, while other samples applied the process route of IF steel. In terms of inclusion area ratio and size, sample 6# (the inclusion area ratio was smallest) and sample 3# had the highest cleanliness among the six samples. Samples 2# and 5# (the average diameter of inclusions was largest) had the worst cleanliness. In the type of inclusions, except for sample 3# where the inclusions were mainly in Al₂O₃, the inclusions in other samples were mainly in Al₂O₃, Ti(C,N) and Ti₄C₂S₂.

Key words： electric vehicle battery shell steel cleanliness inclusion aluminum oxide (Al₂O₃) Ti(C,N)
