AISI 316 (CF8M) stainless hlau peev casting impeller los ntawmTuam Tshoj steel foundrynrog CNC machining cov kev pabcuam yog muab nrog cov nqi sib tw.
CF8M yog cov cam khwb cia austenitic stainless hlau uas them los ntawm ASTM A351, ASTM A743 thiab ASTM A744 tus qauv. CF8M sib npaug rau SS 316 / F 316 thiab Suav Standard 0Cr17Ni12Mo2. CF8M yog molybdenum bearing hloov kho ntawm CF8 alloy thiab yog cov cam khwb cia sib npaug ntawm wrought AISI 316 Stainless hlau. CF8M tau txhais hauv ASMT A351, ASMT A743 thiab ASTM A744, uas yog rau lub hom phiaj casting nkaus xwb. SS 316 yog txhais nyob rau hauv ASTM A240 thiab ASTM A276, nws yog rau phaj, ntawv, sawb lossis stainless hlau tuav. Lwm qib yog lub npe hu ua F316, uas yog los ntawm ASTM A182 rau forged qhov chaw nkaus xwb. TP316 yuav pom hauv ATSTM A376 rau cov yeeb nkab nkaus xwb. Cov ntawv thov tseem ceeb ntawm CF8M cam khwb cia stainless hlau npog: impellers, propellers, twj tso kua mis, valve lub cev thiab xovxwm daim hlau.
Kev nqis peev (poob ciab) casting yog ib txoj hauv kev ntawm precision casting uas ua rau cov ntsiab lus nyob ze-net-puab cov ntaub ntawv siv rov ua cov qauv siv quav ciab.Kev nqis peev castinglos yog poob ciab yog cov txheej txheem hlau uas feem ntau siv cov qauv siv quav ciab ncig los ntawm lub plhaub ceramic los ua cov pwm ceramic. Thaum lub plhaub dries, siv quav ciab yog melted tam sim ntawd, tawm tsuas yog cov pwm. Tom qab ntawd cov khoom siv casting yog tsim los ntawm cov hlau molten rau hauv cov pwm ceramic.
Raws li qhov sib txawv binders rau lub plhaub tsev, lub peev casting yuav muab faib ua silica sol binder peev casting, dej iav binder peev casting thiab peev casting nrog lawv cov khoom sib tov ua cov ntaub ntawv binder. Silica sol yog ib yam dej-raws li khi nrog ib tug silicic acid colloid qauv. Nws yog ib tug polymer colloidal tov nyob rau hauv uas heev dispersed silica hais yog soluble nyob rau hauv dej. Cov colloidal hais yog spherical thiab muaj ib txoj kab uas hla ntawm 6-100nm. Cov txheej txheem ntawm peev casting los ua lub plhaub yog txheej txheem ntawm gelling. Muaj ntau yam cuam tshuam rau gelation, feem ntau yog electrolyte, pH, sol concentration thiab kub. Muaj ntau hom kev lag luam silica sols, thiab feem ntau siv yog alkaline silica sol nrog cov ntsiab lus silica ntawm 30%. Txhawm rau kov yeej qhov tsis txaus ntawm lub plhaub ntev ua lub voj voog ntawm silica sol plhaub, ib qho kev ziab silica sol tau tsim nyob rau xyoo tas los no. Cov txheej txheem ntawm kev ua silica sol plhaub yog qhov yooj yim. Txhua txheej txheem muaj peb txheej txheem: txheej, xuab zeb, thiab ziab. Txhua tus txheej txheem yog rov ua ntau zaus kom tau txais lub plhaub multilayer ntawm qhov yuav tsum tau ua kom tuab.
Hauv silica sol plhaub ua txheej txheem, ziab yog txheej txheem tseem ceeb tshaj plaws. Los ntawm kev ziab, cov dej yog volatilized, silica sol gels, thiab cov khoom refractory yog ruaj khov ua ke, yog li tau txais lub plhaub muaj zog. Qhov no yog ib qho kev npaj zoo rau lub tom ntej casting.
Lub casting tau txais los ntawm silica sol plhaub ua cov txheej txheem muaj qis nto roughness, siab qhov tseeb thiab ntev lub plhaub ua voj voog. Cov txheej txheem no yog siv dav hauv casting high-temperature heat-resistant alloys, heat-resistant steels, stainless steels, carbon steels, low alloys, aluminium alloys and copper alloys.
Lub silica sol precision poob ciab peev casting txheej txheem yog tsim rau repeatable ntau lawm ntawmnet puab casting Cheebtsamlos ntawm ntau yam sib txawv hlau thiab kev ua haujlwm siab alloys. Txawm hais tias feem ntau yog siv rau cov me me castings, cov txheej txheem no tau siv los ua tiav qhov rooj dav hlau qhov rooj, nrog cov hlau castings txog li 500 kgs thiab aluminium castings txog li 50 kgs. Piv rau lwm cov txheej txheem casting xws li tuag casting lossisxuab zeb casting, nws tuaj yeem yog tus txheej txheem kim. Txawm li cas los xij, cov khoom uas tuaj yeem tsim tau siv peev casting tuaj yeem suav nrog cov duab sib txawv, thiab feem ntau cov khoom raug cam khwb cia nyob ze cov duab, yog li yuav tsum tau me me los yog tsis muaj rework ib zaug cam khwb cia.
