| 目的 为了满足汽车制造钢板选材和规范汽车钢板进厂检验评价的需求,总结国内外表面粗糙度测量标准的特点,通过与国内外试验室开展比对试验,在积累大量测试数据的基础上,制定出一种汽车板表面粗糙度检测试验方法。 方法 针对汽车材料试验室钢板表面粗糙度测试的实际需求,设计完整的规范仪器测量条件设置和评价条件选择内容,制定测量汽车板表面粗糙度的 100 mm×100 mm 正方形试样上的编号、轧向标注和具体测量位置图,规范测试位置;提出试样制备要求;描述关键测试流程要求,形成一套方便测试现场使用的标准化作业程序。 结果 汽车用毛化冷轧板的表面结构,决定了取样长度分别为 0. 8 mm 和 2. 5 mm 时,表面粗糙度测量值相差不大;热轧板的表面粗糙度测量值,符合随取样长度的增大而增大的规律。 结论 该试验方法是与 ISO 国际标准接轨、突出现场实用性,可在汽车行业通用的汽车板表面粗糙度检测试验方法。 |

| Objective In order to meet the requirement both in raw materials selection of automobile steel plate and standardization of the incoming inspection & valuation, the surface roughness measuring standard characteristics in domestic and overseas fields were summarized, contrast testing with domestic and overseas labs was carried out, and an automobile steel plate surface roughness detecting & testing method was formulated via accumulating a large number of data. Methods Aiming at the actual requirement of steel plate surface roughness testing of automobile materials labs, a complete testing parameters setting and evaluation conditions selection details were designed, the chart with serial number, rolling direction labeling and specific testing location of a 100 mm × 100 mm square sample was formulated, in order to standardize the testing locations selection. The requirement of test sample preparation was proposed. The requirement of key testing procedures was presented, and a set of standardized operation programs convenient for applying in the testing site were formed. Results The surface structure of automobile textured cold rolled steel sheet led to little difference in the surface roughness measurement data when the sampling length was 0. 8 mm and 2. 5 mm, respectively. The surface roughness measurement data of hot rolled steel plate increased correspondingly along with the sampling length. Conclusion The method integrated with the ISO international standard, highlighted the site practical nature, and could be universally applied in surface roughness testing for automobile steel plate in automobile industry. |
