| 摘 要： | 针对消失模铸造灰铸铁过程中石墨形态及力学性能不稳定的问题,通过在生产条件下附铸阶梯试样及试棒的方法,研究了不同孕育处理方法对消失模铸造灰铸铁组织和性能的影响。结果表明,浇注过程中进行瞬时孕育并控制孕育量在一个适宜的范围内,可明显改善石墨形态和基体组织,同时力学性能得到提高。瞬时孕育量为0.25%时,可基本消除灰铸铁过冷石墨,同时细化基体,抗拉强度较炉前孕育试样提高15 MPa。

| Abstract: | Because of graphite morphology and matrix microstructure were unstable in the process of lost foam casting,influence of inoculation method on microstructure and performance of gray cast iron was studied by casting ladder samples and test bars attached to cast produced via lost foam casting.The results showed that graphite morphology,matrix microstructure were obviously improved and mechanical properties increased by instantly inoculating and controlling the suitable inoculation quantity.Instant inoculation ... |
