摘　　要：基于８个钢厂、３个钢种（Ｑ２３５钢、２０钢、轨钢）的５２０炉钢的化学成分全分析数据，研究了各钢厂由铁矿石带入钢中残留痕量元素的种类和含量水平。研究表明，使用当地铁矿石资源，矿石中的有些痕量元素会带入钢中，赋予钢材具有地方资源特色。By comprehensive chemical analysis of samples taken from 520 heats for three steel grades(steel Q235,20,rail steel)which were collected from eight plants,the content of residual trace elements brought by iron ores into steels is given It shows that by using local iron ore resources some trace elements in those iron ores are brougth into steels and make them particular with local characteristics

关 键 词：矿石 残留痕量元素 化学成分 钢
