针对目前VAR法制备TA10合金铸锭后续加工卷板存在的不足,初步分析电子束冷床炉熔炼过程中的组元挥发机理,研究TA10合金在电子束冷床炉上的单次熔炼工艺。结果表明,经电子束冷床炉单次熔炼的TA10合金热连轧板坯化学成分均匀,铸锭宏观组织均匀,满足卷板的后续加工要求。 Aiming at the shortcomings of the current processing of the TA10 alloy ingot, the component evaporation mechanism in the electron beam cold bed furnace smelting process is analyzed. The single melting process of the TA10 alloy on the electron beam cold bed furnace is studied. The results show that the chemical composition of TA10 alloy hot rolling slab melted by electron beam cooling bed furnace is uniform and the macrostructure of ingot is uniform, which meets the subsequent processing requirements of coil.
