摘　　要：稀土复合作用可以进一步提高细化剂或细化元素的细化效果,其主要复合方式有:两种稀土复合、稀土与非稀土元素复合、稀土与AlTiB或AlTiC细化剂复合。本文主要介绍了这几种复合方式细化作用和机理的研究进展,分析总结了稀土复合细化研究过程中存在的问题,并对稀土复合作用的研究发展趋势提出了展望。The combined effect of the rare earth and other elements can further improve the refinement effect of refiner or refining elements,its main combined way has the following several kinds:two kinds rare earth,rare earth with non-rare earth elements,rare earth with AlTiB or AlTiC.This paper mainly introduces the progress in the study of the composite refining effect and mechanism of these combined ways,summarizes the problems existing in the study of rare earth recombination refinement and puts forward some views on the development trend of rare earth recombination.
