我所对钢中稳定夹杂成分的测定原来采用粉末电弧法,以后改用以钴作内标的—米光栅ICP摄谱法。现在使用ICP/5500仪器。一试样处理氧化夹杂物在钢中易产生偏析,因此我们采用合成标样进行条件试验及生产校对。合成标样中各氧化物组分均采用光谱纯试剂,经105℃烘干恒重,按不同配比称取一定量于玛瑙研缽中,用无水乙醇研磨至均匀,然后贮存干燥器中备用。加工成棒状的生产试样置于电解槽中,经恒电流电解40～50小时,将电解残渣经处理碳化物、过滤、
My determination of the stability of the inclusions in the steel composition originally used powder arc method, later switched to cobalt as the internal standard - rice grating ICP spectroscopy. Now use the ICP / 5500 instrument. A sample processing oxide inclusions prone to segregation in the steel, so we use the synthetic standard for conditional testing and production proofreading. Synthesis of the standard sample of the oxide components were used spectroscopy pure reagent, dried at 105 ℃ constant weight, according to different proportions weighed a certain amount of agate mortar, with anhydrous ethanol to a uniform grinding, and then stored in the dryer spare. Processed into a rod-shaped production sample placed in the electrolytic cell, the constant current electrolysis 40 to 50 hours, the electrolytic residue treated carbide, filtered,
