| titleOfInvention | Metal mold microalloying of rare earth D type Graphite Iron Cast glass mold and preparation method thereof |
| abstract | The invention discloses a kind of metal mold microalloying of rare earth D type Graphite Iron Cast glass mold and preparation method, does described glass mold comprise the combination of following masses per-cent: C? 3.35 ~ 3.7%, Si? 2 ~ 2.2%, Mn0.4 ~ 0.6%, Cr? 0.3 ~ 0.4%, Mo? 0.4 ~ 0.5%, Ni0.9 ~ 1.1%, V? < 0.02%, Al < 0.02%, Cu < 0.02%, Ti0.05 ~ 0.1%, RE0.02 ~ 0.05%, all the other are Fe and inevitable impurity.Metal mold microalloying of rare earth D type Graphite Iron Cast glass mold of the present invention and preparation method thereof, can solve due to too fast the produced whitening tendency of metal mold cooling; Complete graphited high temperature annealing, makes finally to obtain ferrite base body tissue; The every integrated performance index of D type Graphite Iron Cast improves significantly, meets the prerequisite requirement of glass mold, adds the mold use life-span. |
