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.
