【摘要】 研究高碳钢中化学成分偏析现象,采用化学分析、红外碳硫仪分析、光谱分析等方法,对浇铸过程不同时间试样、样品同一层面的不同点、同一样品不同层面的化学成分进行测量,对各种方法的测试结果进行比较分析,结果表明,Mn,S i,S,P元素分布基本稳定,C元素分布易波动。对取样条件、试样制备、测量方法进行探讨,指出高碳钢化学分析的控制要点。更多还原

【Abstract】 To research the chemical composition segregation phenomenon of high carbon steel.By means of chemical analysis,infrared C-S-instrument and spectrum analysis,the chemical compositions of different time samples in casting,different spots at the same layer of a sample and the different layer of the same sample are measured.The measure results with different methods are compared and analyzed,and the results indicate that the distributions of Mn,Si,S and P elements are stable basically,the distribution of C element is prone to fluctuation.The sampling conditions,sample preparation and measure methods are discussed and the control points of chemical analysis of high carbon are pointed out.更多还原
