It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...

本文介绍了稀土高铝耐热球墨铸铁的生产实践、化学成分；探讨了稀土作用及其用量和控制；论述了稀土和铝加入方式以及冷却速度对金相组织的影响；并对铸造工艺、铸件缺陷及分析、耐热性能及使用效果作了阐明。试验和使用证明：稀土高铝耐热球墨铸铁在1050～1100℃长时间工作不起氧化皮，热强度800℃时，14～19kg/mm~2，900℃时≥13.3kg/mm~2，室温强度近于HT30—54，a_k≈2～6kg·M/cm~2，锤击铸件或浇冒口，很难碎裂，并能机械加工。可以认为是以我国富产资源为原料，能用各种炉子熔炼、耐热和综合机械性能均较高硅、中硅中铝球铁、高铝片墨铸铁为高的一种耐热铸铁，也是镍铬系耐热材料较好的替代品。
