高硅钼铁素体球铁排气管材质试验研究

An Experimental Research on Materia l of High Silicon and Molybdenum Ferrite Nodular Iron Ven t -pipe

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。

To meet the need of energy saving and e nvironment protection,a new kind of material for vent -pipe———high silicon and molybdenum ferrite nodular iron was developed.Aiming at the specification of nodular iron with high silicon and mloybdenum,a series of technology factor experim ent and tests of verifying technolog ies were carried through.And the opt imum chemical compo-sition was confirmed and a reasonabl e melting process was obtained.
