本文探讨了CaO-CaF_2-Al_2O_3渣系中CaF_2对熔渣碱度、粘度的影响。研究了焊剂中CaF_2含量与焊缝金属中[H]_(?)、[O]的关系,并利用扫描电镜(SEM)和电子探针(EPMA)对焊缝金属中非金属夹杂物的形态和数量进行了分析。
In this paper, the effect of CaF_2 on the basicity and viscosity of slag in CaO-CaF_2-Al_2O_3 slag system was investigated. The relationship between the content of CaF_2 in flux and [H] _ (?) And [O] in weld metal was studied. The morphology of nonmetal inclusions in weld metal was characterized by scanning electron microscope (SEM) and electron probe And the quantity is analyzed.
