为了满足汽车节能、环保要求,研究了新的排气管材质——高硅钼铁素体球铁。针对高硅钼球铁的技术要求,先后通过一系列工艺因数多水平试验和工艺验证性试验,最终得出最佳的化学成分、球化孕育处理方法及合理的熔化工艺。
In order to meet the automobile energy saving and environmental protection requirements, the new exhaust pipe material - high silicon molybdenum ferrite ductile iron was researched. According to the technical requirements of high silicon molybdenum ductile iron, it has passed a series of process level multi-level tests and process confirmatory tests, and finally obtained the best chemical composition, the ball-inoculation method and the reasonable melting process.
