| 摘 要： | 本文通过试验研究了铬、钨、稀土及钛元素对特种铸铁的抗生长性，抗氧化性和抗铝液熔蚀性的影响，认为铬能细化，稳定珠光体且与铝液作用生成复杂的，不易溶于铝液的金属间化合物；钨可细化晶粒和石墨；稀土有细化石墨，改善石墨形态及脱氧净化铁水的作用，钛用作用不明显。

| Abstract: | This paper presents the effects of Cr,W,Re and Ti on special cast iron(crucible materi-al for melting aluminium) in growth resistance,oxidation resistance and melt-off resistance to melted aluminium. Cr can refine, fix pearlite and produce sophisticated metallide melted difficulty in melting aluminium by chemosynthesis; W can refine grain and graphite;Re canrefine graphite,improve the figure of graphite and make melted iron eliminate--oxygen and clean-up;the effect of Ti is unknown. |
