Thaum koj hnov 'stainless steel xuab zeb casting foundry,' feem ntau lub siab dhia ncaj nraim mus rau qhov loj, ntxhib castings rau cov tshuab hnyav. Qhov ntawd yog qhov tseeb, tab sis nws kuj yog qhov loj tshaj qhov ua kom yooj yim hauv txoj haujlwm. Zaj dab neeg tiag tiag tsis yog hais txog kev nchuav hlau rau hauv cov xuab zeb pwm; Nws yog hais txog kev tswj kev sib ntaus sib tua ntawm cov dej dynamics, metallurgy, thiab sheer unpredictability ntawm xuab zeb. Cov lus cog tseg ntawm ib qho nyuaj, corrosion-resistant ib txwm yog qhov tsis sib xws nrog qhov tseeb ntawm shrinkage porosity, deg tag kev txwv, thiab kev sib ntaus mus ib txhis tiv thaiv kev suav nrog. Kuv tau pom ntau tus qauv tsim los hauv qhov zoo tshaj plaws rau kev nqis peev casting tab sis npau suav phem rau cov xuab zeb, tsuas yog vim qhov sib txawv tsis to taub upfront.
Cov xuab zeb nws tus kheej yog txheej txheem
Nws pib nrog pwm, pom tseeb. Tab sis cov xuab zeb ntsuab piv rau cov xuab zeb-bonded tsis yog ib qho kev xaiv xwb; nws yog kev cog lus rau cov teeb meem sib txawv. Peb siv ntau furan tsis muaj ci rau peb cov haujlwm stainless hauv lub khw. Qhov kev ruaj ntseg ntawm qhov ntev yog qhov zoo dua rau qhov loj dua, qhov hnyav dua peb feem ntau cuam tshuam nrog, xws li cov twj tso kua mis lossis lub cev valve. Tab sis kev lag luam tawm yog qhov gassing. Yog tias qhov cua hauv qhov chaw tsis pom, lossis yog tias cov xuab zeb sib tov tawm los ntawm ib feem, koj yuav tau txais pinholing rau ntawm qhov chaw casting uas zoo li zoo tom qab shakeout tab sis pom tias muaj teeb meem thaum lub sij hawm machining. Nws yog qhov ua tsis tau ncua, qhov phem tshaj plaws.
Tom qab ntawd muaj cov xuab zeb thermal cwj pwm. Stainless, tshwj xeeb tshaj yog 300 series zoo li 304 lossis 316, nchuav ntawm qhov kub thiab txias thiab muaj qhov sib txawv ntev. Cov xuab zeb yuav tsum tau tiv taus qhov kub ntawd yam tsis tau tawg sai heev thiab ua rau yaig, tab sis kuj tsis ua nruj heev uas nws txwv kev cog lus thiab ua rau kub tearing. Nws yog ib qho kev sib npaug. Kuv nco qab ib pawg ntawm CF8M (316 sib npaug) rooj vag li qub uas peb tau khiav. Kev pib khiav tau zoo ib yam kua muag kub ntawm qhov sib txuas ntawm flange thiab lub cev. Peb taug qab nws rov qab tsis yog rau tus qauv lossis lub rooj vag, tab sis rau cov xuab zeb rov qab tau siab dhau lawm. Cov xuab zeb tau poob ntau dhau ntawm nws qhov qub refractoriness thiab ua kom sov tawm mus tsis sib xws. Ib qho xuab zeb tshiab kho nws. Nws yog cov khoom siv-theem kev sib cuam tshuam uas koj tsuas yog kawm los ntawm kev kub hnyiab los ntawm cov khoom seem.
Thiab reclamation yog nws tus tsiaj nyaum. Koj tsis tuaj yeem khaws cov xuab zeb rov ua dua ib ntus rau kev ua haujlwm tsis zoo.
