摘　　要：文章对3种补缩工艺下的锆合金铸锭冒口及其化学成分进行对比分析,研究不同的铸锭补缩工艺对锆合金铸锭冒口深度及铸锭化学成分的影响。结果表明,适当的补缩电流制度和补缩时间,既能减少铸锭冒口深度,也能保证其化学成分与铸锭整体的一致性。The paper analyzed the effect of different feeding processes on riser depth and chemical composition of zirconium alloy ingot. The results showed that the reduction in riser depth could be made and uniformity in riser chemical composition of the ingot as a whole could be guaranteed using appropriate feeding current system and feeding time.
