摘要
研究了不同精炼处理工艺对铝液精炼效果的影响,分析了精炼工艺对不同变质剂变质效果的影响。结果表明,氩气旋转喷吹技术与盐类精炼复合的精炼工艺,可提高铝液的精炼效果;氩气旋转喷吹精炼与钠盐变质处理同时进行的复合工艺,可降低钠盐变质处理时的吸气倾向;氩气旋转喷吹精炼能减少铝液中锶的烧损,提高Sr的变质效果。
Effects of different degassing processes on molten aluminum and on the modification efficiency of different modifier with Na and Sr were investigated.The results show that the rotating-injection argon gas degassing technology combining with the salt degassing can improve the molten aluminum degassing efficiency,and the rotating-injection argon gas degassing technology combining with the Na salt refining process can decrease the H2 absorption during refining process.In addition,the rotating-injection argon gas degassing technology can reduce the strontium burning in the molten aluminum,improving the modification efficiency of strontium.
