影响球化剂中氧化镁含量分析值的若干因素

Some Factors Influencing Analysis Results of MgO Content in Nodularizer

讨论了取样方法、制样方法、制样粉碎时间、样品存放时间、摇样时间、摇样后样品放置时间和不同操作人员对同一球化剂样品的氧化镁分析值的影响。

Some factors influencing the analysis results of MgO content in the nodularizer were investigated. The factors included.sampling methods, sample preparation methods, sample pulverizing time, time interval from sample preparation to chimical analysis, sample shaking time, time interval from sample shaking to sample filtering and different operators.
