摘　　要：对基于气泡浮游法的传统铝熔体除氢理论进行了分析和评述,介绍了最新提出的铝熔体覆盖保护和化学净化原理,并对上述两种理论的净化作用特点进行了分析。覆盖保护加上净化熔剂层源源不断析出的净化原子,可以确保铝熔体中的含氢量越来越低。Traditional degassing theories based on gas-bubbles were analyzed and reviewed. A new purifying theory of aluminum melt covering and protecting ＆ atomic purification theory was introduced. In the meantime, the difference among these theories was pointed out also. With a new covering and protecting flux which providing a continuous supply of purifying atomic, hydrogen content in aluminum melt can be more and more low.
