A series of fused CaF2-SiO2-CaO-based fluxes geared towards submerged arc welding has been prepared with incremental TiO2 additions. Through systematic investigation on physical properties, quantitative relationship between TiO2 content and corresponding structural information has been established, and the roles played by TiO2 have been profiled. It is found that TiO2 has been introduced into the silicate network by acting as network-former, increasing the degree of polymerization while lowering the strength of the flux.

TiO2 在 CaF2-SiO2-CaO-TiO2 埋弧焊焊剂中的结构作用

已经制备了一系列适用于埋弧焊的熔融 CaF2-SiO2-CaO 基焊剂，其中添加了增量 TiO2。通过对物理性质的系统研究，建立了 TiO2 含量与相应结构信息之间的定量关系，并对 TiO2 的作用进行了剖析。发现 TiO2 作为网络形成剂被引入到硅酸盐网络中，增加了聚合度，同时降低了助焊剂的强度。
