Sanding casting steel investment casting inoreva kugadzira fusible modhi ine fusible zvinhu, kupfekedza akati wandei akaturikidzana akasarudzika mabhanhire pairi, kuomesa uye kuomesa kuumba yakakosha goko, uyezve kushandisa chiutsi kana mvura inopisa kugadzira mold.Nyungudusa modhi mugoko, wobva waisa goko mubhokisi rejecha, zadza zvakatenderedza nejecha rakaoma kuumba, isa mold muchoto chekugocha kuitira kupisa kwakanyanya, uye dururira simbi yakanyungudutswa muforoma yekukanda kana goko mushure mekugocha. Uye kuwana castings.
Iyo nzira ndeyekupisa zvakasiyana-siyana zvekukanda kune tembiricha ye860-900 ℃, chengetedza matrix yepakutanga zvese austenitized, wozotonhorera mumafuta kana munyu wakanyungudutswa kuti uwane kudzima, uyezve kupisa, kupisa, kupisa uye kutsamwa pa250-350 ℃, uye iyo yekutanga matrix inoshandurwa kuita Tempered martensite uye yakachengetwa austenite chimiro, iyo yekutanga spherical graphite chimiro inoramba isina kuchinjika.Ductile castings inoda kuomarara kwepamusoro semabhengi, uye iyo idler vhiri gungano rinowanzo kudzimwa uye kudzikamiswa pane yakaderera tembiricha.
Iwo akarapwa akakandwa ane kuomarara kwakanyanya uye kumwe kuoma, Liaoning cast simbi inochengeta iyo yekuzora zvimiro zvegraphite, uye yekupfeka kuramba inovandudzwa.Zvigadzirwa zvakawanikwa nekukandira kwekudyara zvakaoma, padyo nechimiro chezvikamu, uye zvinogona kushandiswa zvakananga pasina kana nekugadzirisa kushoma.Haikodzere chete kukanda kwemhando dzakasiyana-siyana uye alloys, asi zvakare inogadzira castings ine yakakwira dimensional kurongeka uye pamusoro pemhando yepamusoro kupfuura dzimwe nzira dzekukanda, uye kunyange dzakaoma, tembiricha inodzivirira uye yakaoma kugadzira ma castings ayo akaoma kukandwa neimwe nzira yekukanda. nzira.Inogona kukandwa neinvestment casting.
