浇注系统

The current theory and application of Al-Si alloy mainly focus on the study of hypoeutectic and eutectic, therefore we systematically analyzed the modification process of hypereutectic Al-Si alloy based on the methods and results of predecessors. Several factors including the modification temperature, the content of modifier, the available holding time, the times of repeat melting , the casting temperature and the speed for cooling have been studied in order to understand its effects to the composition, function and performances of primary silicon and eutectic silicon.

中文摘要本文针对目前Al-Si合金相关应用和理论的研究多集中于亚共晶和共晶合金的情况，在前人的研究成果和研究方法的基础上，对过共晶Al-Si合金变质处理进行了较为系统的分析，研究了变质剂的成分配比、变质温度、变质剂的加入量、变质后的静置时间、浇注温度及冷却速度等因素对过共晶铝硅合金中初晶硅和共晶硅的大小、形状、数量和分布的影响。
