摘要
对镁热法生产海绵钛还原过程加镁量、加镁方式、还原副产物排放等对海绵钛质量的影响进行分析。结果表明,海绵钛等级随还原剂镁中杂质元素含量的增多而降低,稳定控制还原过程加镁量可稳定反应的液位并提高0A级海绵钛的比例;0A级海绵钛炉次冷凝镁脱气耗时比≤1级品炉次平均少1h。熔镁与加镁耗时对产品品级率影响不明显,还原过程副产物氯化镁的顺利排放能提高海绵钛的等级率。
The effects of magnesium dosage,feeding mode of magnesium,and discharge of reduction byproduct in magnesium reduction process on quality of titanium sponge were analyzed.The results show that grade of titanium sponge drops with increase of impurity elements in magnesium.Stable control of feeding amount of magnesium can stabilize liquid level of reaction and improve proportion of 0A grade titanium sponge.Condensed magnesium degassing time of 0A grade titanium sponge is one hour shorter than that of≤1grade titanium sponge.Time-consuming of magnesium adding and molten has little effect on grade.Smooth discharge of by-product of magnesium chloride can improve grade of titanium sponge.
