Maitiro Maitiro e Precision Casting

Stainless simbi precision kukandira izere mold kugona. Kune yakaonda uye yakaoma castings, yakakwirira fluidity inodiwa, kana zvisina kudaro, iyo mold yose haigone kuzadzwa. Kukandwa kunova tsvina. Iyo chaiyo fluidity yesimbi isina simbi inonyanyoenderana neyakaumbwa nemakemikari ayo uye tembiricha yekudurura. Semuenzaniso, alloys ane eutectic components kana padyo ne eutectic components, pamwe nema alloys ane nhete yechigadzirwa tembiricha renji, vane fluidity yakanaka; phosphorus musimbi yakakandwa inogona kuvandudza fluidity, nepo sarufa inoita kuti fluidity iwedzere. Kuwedzera tembiricha yekudurura kunogona kuvandudza fluidity.

Sezvo shrinkage yesimbi isina Stainless simbi chaiyo yekukanda inodarika zvakanyanya iyo yesimbi yakakandwa, kuitira kudzivirira shrinkage cavities uye shrinkage kuremara mukukanda, mazhinji emaitiro ekukanda anotora matanho akadai seanosimuka, simbi inotonhora, uye rubatsiro kuti uwane kusimba kwakatevedzana.

Kuti udzivise kuitika kwe shrinkage cavities, shrinkage porosity, pores uye kuputika musimbi isina tsvina, ukobvu hwemadziro hunofanira kunge hwakafanana, makona akapinza uye zvimiro zvekona-kurudyi zvinofanirwa kudziviswa, sawdust inowedzerwa kune jecha rekukanda, coke inowedzerwa. kupakati, uye hollow type Cores nemafuta ejecha cores kuvandudza kudzoreredza uye kupenya kwemhepo kwejecha mold kana cores.

Nekuda kwekushayikwa kwemvura yesimbi yakanyungudutswa, kuitira kudzivirira zvipingamupinyi zvinotonhora uye kusakwana kudururwa kwesimbi kukanda, ukobvu hwemadziro esimbi castings haifanirwe kunge iri pasi pe8mm; shandisa kukanda kwakaoma kana kupisa kupisa; zvakakodzera kuwedzera tembiricha yekudira, kazhinji 1520 ° ~ 1600 ° C , Nekuti tembiricha yekudurura yakakwira, simbi yakanyungudutswa ine dhigirii yekupisa, uye inogara iri mvura kwenguva yakareba, uye fluidity inogona kuvandudzwa. Nekudaro, kana tembiricha yekudururira yakanyanyisa, zvinokonzeresa kukanganisa senge tsanga dzakakora, kuputika kunopisa, pores uye jecha rinonamira. Naizvozvo, kazhinji, madiki, akatetepa-akakomberedzwa uye akaoma-kuumbwa-kuumbwa kwakaringana, tembiricha yekudurura ndeye tembiricha yekunyungudika kwesimbi + 150 ℃; chimiro chegadziriro yekudurura iri nyore uye chiyero chechikamu chakakura kudarika chesimbi yakakandwa; tembiricha yekudurura yezviumbwa zvakakura uye zvakakora-madziro Zvinenge 100 ° C yakakwirira kupfuura nzvimbo yayo yekunyungudika.
