摘要
EH36-shipbuilding steel has been welded by CaF2-ZrO2 fluxes with designed ZrO2 additions.为了分析合金元素的转移行为，推测了可能发生的化学和电化学反应。通过应用气体-熔渣-金属平衡模型，验证了 ZrO2 在 SAW 过程中的分解，并量化了 ZrO2 的 O 供应能力。在整个成分范围内，O 含量被控制在 220 至 400 ppm 的良好范围内，Zr 含量的转移量达到最大值 120 ppm。研究进一步证明，添加 ZrO2 会在焊接金属中造成明显的硅损失。
Element Transfer Behaviors of Agglomerated CaF2-ZrO2 Fluxes in EH36-Shipbuilding Steel Subject to High-Heat Input Submerged Arc Welding
EH36-shipbuilding steel has been welded by CaF2-ZrO2 fluxes with designed ZrO2 additions. Possible chemical and electrochemical reactions have been postulated to analyze alloying element transfer behaviors. The decomposition of ZrO2 during SAW has been validated by applying the gas–slag–metal equilibrium model and the O supply capacity of ZrO2 has been quantified. For the entire compositional range, O content has been controlled within a well-maintained range from 220 to 400 ppm, and the transferred quantity of Zr content reaches to the maximum value of 120 ppm. It is further demonstrated that ZrO2 addition incurs appreciable Si loss within the weld metal.
