工业炉用耐火浇注料气孔率检测的不确定度评定

Evaluation of Uncertainty on Porosity of Refractory Castables for Industrial Furnaces

气孔率是现代工业炉用浇注料的一种重要性能指标。浸液法测定气孔率在物理性能检测中已得到广泛应用。对浸液法测量气孔率的不确定度来源进行了分析,并对结果的不确定度进行了认真评定,最终给出了扩展不确定度。

Porosity is an important property for castables applicated at modem industrial furnaces. It is widely used to test castable on porosity by submergence in physical property inspection, This paper analyses the source of uncertainty of porosity tested by submergence and evaluate the uncertainty.
