Inoculation yog txheej txheem tsim tau zoo uas tsis yog tsuas yog tiv thaiv carbide tsim, tab sis kuj tswj qhov loj thiab daim ntawv ntawm graphite flake hauv cov hlau cam grey. Daim ntawv no tshuaj xyuas qee qhov kev txhim kho uas tau tshwm sim hauv inoculants thiab inoculating txheej txheem grey cam khwb cia hlau.
Yuav ua li cas yog inoculation ntawm cam khwb cia hlau?
"Inoculation ntawm molten cam khwb cia hlau" yog hais txog kev taw qhia ntawm nuclei rau hauv cov yaj thiaj li yuav cuam tshuam cov txheej txheem solidification los yog cov qauv tsim nyob rau hauv lub casting nyob rau hauv ib txoj kev tshwj xeeb. Nuclei yog cov khoom zoo uas yog ≤ 4 µm hauv qhov loj thiab ua haujlwm ua crystallization chaw rau graphite nag lossis daus.
Yuav ua li cas yog inoculant hauv foundry?
Inoculants yog FeSi raws li alloys uas muaj cov khoom ua tib zoo sib npaug ntawm cov khoom nquag tsim los tswj cov microstructure thiab txhua yam khoom ntawm cam khwb cia hlau.
Vim li cas thiaj siv tau rau hauv cov hlau casting?
Lub hom phiaj ntawm kev tsis muaj kab mob yog txhawm rau muab lub substrate tsim nyog uas tso cai rau graphite kom loj hlob nrog qis qis qis. Inoculation yog qhov tseem ceeb dua thiab yuav tsum tau ntxiv cov hlau ntau dua li cov hlau grey.
Yuav ua li cas yog GREY cam khwb cia hlau?
Cov khoom siv no yog ternary Fe-C-Si alloy. Grey cam khwb cia hlau yog tus cwj pwm los ntawm nws cov graphitic microstructure. Feem ntau cov cam khwb cia hlau muaj cov tshuaj muaj pes tsawg leeg ntawm 2.5 txog 4.0% carbon, 1 txog 3% silicon, thiabseem yog hlau.
Pom zoo:
Cam khwb cia hlau yog dab tsi?
cam khwb cia hlau yog ib pawg hlau-carbon alloys nrog cov ntsiab lus carbon ntau dua 2%. Nws cov txiaj ntsig tau muab los ntawm nws qhov ntsuas kub qis qis. Qhov txawv ntawm hlau thiab cam khwb cia yog dab tsi? Wrought Iron yog hlau uas tau ua kom sov thiab ua haujlwm nrog cov cuab yeej.
Yuav cam khwb cia hlau tawg iav saum qhov cub?
Vim cam khwb cia hlau yog ntxhib thiab hnyav, zawv zawg rau ntawm iav nto tuaj yeem ua rau me me tawg ua rau thaum kawg ua rau lub cooktop tawg. Yog li ntawd, tsis txhob tso lub lauj kaub rau ntawm lub khob lossis zawv zawg lawv, maj mam nqa los yog muab tso rau ntawm qhov cub kom tsis txhob muaj kev puas tsuaj.
Koj puas tuaj yeem noj txiv lws suav hauv cam khwb cia hlau?
Cov khoom xyaw acidic xws li txiv lws suav, txiv qaub, thiab cawv tuaj yeem ua rau hauv lub lauj kaub zoo-seasoned cam khwb cia hlau rau lub sijhawm luv luv. Koj tuaj yeem sauté txiv lws suav hauv cov hlau cam, tab sis tsis txhob sim ua cov kua txiv lws suav ntev.
Vim li cas grey cam khwb cia hlau nthuav dav rau qhov txias?
Kev nthuav dav hauv cov hlau grey yog vim muaj cov pa roj carbon dawb (graphite). … Txhua yam hlau uas muaj carbides muaj tsawg nthuav dav ntawm qhov txias thiab qhov siab tshaj plaws nthuav dav yog nyob rau hauv cov ntaub ntawv nodular/ductile hlau.
Koj puas tuaj yeem vuam grey cam khwb cia hlau?
Grey cam khwb cia hlau yog feem ntau hom cam khwb cia hlau. … Nws yog ntau dua thiab vuam ntau dua li cov hlau cam dawb. Txawm li cas los xij, nws tseem ua rau muaj kev sib tw rau yav tom ntej welders raws li cov graphite flakes nyob rau hauv grey cam khwb cia hlau tuaj yeem nkag mus rau hauv lub pas dej ua ke kom ua rau cov hlau embrittlement.
