本文研究了CaO-CaF_2-Al_2O_3系中碱度与[O]和冲击韧性之间的关系。文中利用与碱度相联系的相对化学活度,分析了复杂渣系中SiO_2、MnO的热力学活度,并讨论了焊接过程中可能达到的Si、Mn脱氧效果。
In this paper, the relationship between basicity and [O] and impact toughness in CaO-CaF 2 -Al 2 O 3 system was studied. In this paper, the relative chemical activity associated with alkalinity was used to analyze the thermodynamic activity of SiO 2 and MnO in complex slag systems. The possible deoxidization effects of Si and Mn during the welding process were discussed.
