摘　　要：对玻璃瓶模具材质的包内微合金处理工艺进行了探索研究,分析比较了微合金化处理前后玻璃瓶模具材质的石墨形态、基体组织、共晶团形貌、硬度及抗氧化性能等。结果表明:经过炉前包内微合金化处理的玻璃模具材质石墨形态明显改善,基体组织中珠光体数量增多且片层间距细小,共晶团组织细小且数目增多,促使碳化物的形成,提高耐热相的稳定性,从而使玻璃瓶模具材质的硬度提高、抗氧化性能明显改善。The technology of ladle micro-alloying for glass mould material was studied, and the graphite shape, matrix, eutectic colony, hardness and oxidation resistance properties of the mould material treated by alloying was compared with that by original process. The results show that after alloying the shape of graphite improves, the number of pearlite and eutectic colony in matrix structure increases obviously and the slice space of them declines distinctly, at the same time, the carbonide forms easy, the stability of heat-resistant phases increases. As a result, the hardness of the mould material enhances and the oxidation resistance is better than before.
