Ntawm ntau yam txheej txheem casting, stainless hlau yog tsuas yog cam khwb cia los ntawm peev casting los yogploj wax casting txheej txheem, vim hais tias nws muaj ntau dua qhov tseeb thiab yog vim li cas cov peev casting kuj muaj npe precision casting.
Stainless hlau yog lub ntsiab lus ntawm stainless thiab acid-resistant steel. Nws yog hu ua stainless hlau uas tiv taus cov tsis muaj zog corrosive media xws li cua, chav, thiab dej. Corrosion steel yog hu ua acid-resistant steel.
Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm cov hlau tsis zoo ib yam thiab cov kua qaub-resistant steel, lawv cov corrosion kuj txawv. Ordinary stainless hlau feem ntau tsis resistant rau tshuaj lom neeg corrosion, thaum acid-resistant steel feem ntau tsis-corrosive. Lub sij hawm "stainless steel" tsis yog tsuas yog hais txog ib hom stainless hlau, tab sis kuj hais txog ntau tshaj li ib puas industrial stainless hlau. Txhua stainless hlau tsim muaj kev ua tau zoo hauv nws cov ntawv thov tshwj xeeb.
Stainless hlau feem ntau muab faib ua martensitic stainless hlau, ferritic stainless hlau, austenitic stainless hlau,austenitic-ferritic (duplex) stainless hlauthiab nag lossis daus hardening stainless hlau raws li lub xeev ntawm microstructure. Tsis tas li ntawd, raws li cov tshuaj muaj pes tsawg leeg, nws tuaj yeem muab faib ua chromium stainless hlau, chromium nickel stainless hlau thiab chromium manganese nitrogen stainless hlau, thiab lwm yam.
Hauv kev tsim khoom, feem ntau ntawm cov hlau tsis xeb hlau yog ua tiav los ntawm peev casting. Qhov saum npoo ntawm stainless hlau castings tsim los ntawm peev casting yog smoother thiab qhov tseeb qhov tseeb yog yooj yim dua los tswj. Tau kawg, tus nqi ntawmpeev casting stainless hlau qhov chawyog qhov siab dua piv rau lwm cov txheej txheem thiab cov khoom siv.
Peev casting, tseem hu ua precision casting los yog poob ciab casting, yog dav siv raws li nws muaj asymmetrical casting nrog zoo heev cov ntsiab lus yuav tsum tau manufactured kuj inexpensively. Cov txheej txheem yuav ua tau ib tug hlau casting siv ib tug refractory pwm ua los ntawm ib tug wax replica qauv. Cov kauj ruam koom nrog hauv cov txheej txheem los yog qhov poob ciab casting yog:
• Tsim ib tug qauv siv quav ciab los yog replica
• Sprue tus qauv siv quav ciab
• nqis peev tus qauv siv quav ciab
• Tshem tawm cov qauv siv quav ciab los ntawm kev hlawv nws (hauv qhov cub lossis hauv dej kub) los tsim cov pwm.
• Force molten hlau ncuav rau hauv pwm
• Txias thiab Solidification
• Tshem tawm sprue ntawm cov castings
• Ua kom tiav thiab polishing tiav cov peev txheej castings
