摘要
低辐射玻璃用银残靶材在熔炼回收时发现有较多浮渣,经分析研究发现浮渣主要为玻璃、Al_2O_3·SiO_2、NiO、Cr_2O_3。浮渣主要影响到木炭对银熔液中氧的吸附,从而致使银锭凝固时最终区域出现鼓泡。采用高除渣率的扒渣工艺,可以有效的解决木炭除氧问题。
Silver residue targets for low-radiation glass were found to have more dross during smelting and recovery.Through analysis and research,it was found that the dross was mainly glass,Al2O3·SiO2,NiO and Cr2O3.The dross mainly affects the absorption of oxygen in silver melt by charcoal,thus resulting in silver ingot solidification,resulting in bubbling in the final area.The removal of oxygen in charcoal can be effectively solved by adopting a slag scraping process with high slag removal rate.
