中文摘要:
      提出一种基于TXRF(Total-Reflection X-ray Fluorescence)的锌层质量标准曲线的理论计算方法。该方法首先利用材料参数和射线源参数建立MCM(Monte Carlo Method)物理模型。然后将某冷轧厂的标准镀锌板锌层厚度值输入仿真物理模型,得到各标准板对应的荧光光子注量。最后将厚度值对光子注量作图建立标准测量曲线,相关系数为0.9992。在相同实验条件下,测得未知镀锌板的荧光光子注量,通过插入法在标准曲线上得到相应的锌层厚度,并与多种方法进行测量比对。结果表明:所提出的计算方法可应用于锌层单位面积质量为50~140 gm-2的常规镀锌板测量。
英文摘要:
      A total-reflection X-ray fluorescence based theoretical calculation method for the standard measurement curve of zinc coating weight is proposed. In this method, the physical model of MCM (Monte Carlo Method) is established by using the materials parameters and the X-ray source parameters. Then the standard zinc coating thickness of a cold-steel rolling mill is input to the simulation physical model, and the fluorescence photon flux corresponding to the standard plate is obtained. Finally, a standard measurement curve is set up by mapping the thickness value to the fluorescence photon flux. The correlation coefficient is 0.9992. Under the same experimental conditions, the fluorescence photon flux of the unknown galvanized plate was measured, and the corresponding zinc layer thickness was obtained on the standard curve by inserting method, and compared with various methods. The results show that the proposed method can be applied to measure the zinc coating weight between 50 and 140 g per unit area of conventional galvanized plate.
