摘要
本文通过研究海绵钛中残留氯化镁的来源以及氯化镁对熔炼系统和钛材质量的影响,分析海绵钛中镁含量的表征数据,指出钛锭中镁含量检测数据偏离海绵钛实际镁含量。通过对不同等级的海绵钛熔炼前后的镁含量进行检测,修订海绵钛内控标准,即对于1级及以上品率的海绵钛,增加熔炼残极控制标准为Mg≤0.03%,有效把控海绵钛中的镁含量,不仅提升海绵钛熔锭品质,也防止熔炼时氯化镁对真空系统造成的影响。
In this paper,by studying the source of residual magnesium chloride in titanium sponge and the influence of magnesium chloride on the smelting system and the quality of titanium material,the characteristic data of magnesium content in titanium sponge were analyzed,and it was pointed out that the measured data of magnesium content in titanium ingot deviated from the actual magnesium content in titanium sponge.Through the different levels of sponge titanium smelting magnesium content test,before and after the revision of titanium sponge internal control standards,namely for level 1 and above product rate of titanium sponge,increased melting residual control standard for Mg 0.03%or less,the effective control of magnesium content in titanium sponge,not only improve the quality of titanium sponge molten ingot,and also to prevent melting magnesium chloride on the impacts of vacuum system.
