回顾了通过钢锭和连铸工艺生产的铸钢中发生 A 和 V 偏析的各种假设机制。对宏观偏析进行了简要的概括描述，然后详细说明了 A 型和 V 型形成理论，特别强调了流体流动、热条件和成分的重要性和相互作用。对最近提出的数学模型进行了讨论，最后提出了最小化铸钢中 A 和 V 偏析的方法。
The various mechanisms postulated for the occurrence of A- and V-segregation in cast steel produced via both the ingot and continous- casting routes are reviewed. A brief general description is given of macrosegregation, followed by a detailed account of the theories of A- and V-formation with particular emphasis on the importance and interaction of fluid flow, thermal conditions, and composition. Mathematical models that have recently been proposed are discussed and, finally, methods to minimize A- and V-segregation in cast steel are suggested.
