Cov kav dej hlauyog cov zoo zoo dua li cov kav hlau cam khwb cia. Cov graphite nyob rau hauv cov hlau cam khwb cia zoo tib yam yog nyob rau hauv nplooj ntawv thiab muaj zog tsawg heev. Yog li zoo tib yam cam khwb cia hlau lub zog yog qhov tsawg, nkig. Lub graphite nyob rau hauv graphite cam khwb cia hlau yog kheej kheej, sib npaug rau lub neej ntawm ntau lub voj voos kheej kheej hauv cov cam khwb cia hlau. Kev cuam tshuam ntawm cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Qhov zoo ntawm cov yeeb nkab hlau siv hauv cov kav dej xa dej:
1. Vim tias ductile hlau yeeb nkab tau txais kev sib koom ua ke, kev tsim kho yooj yim dua, tuaj yeem txhim kho kev tsim kho, txhim kho kev tsim kho, txo tus nqi tsim kho, thiab feem ntau ntawm cov kev sib txuas tau txais kev sib txuas ntawm cov roj hmab nplhaib, kev ua haujlwm yooj yim, tuaj yeem ua rau lub sijhawm tsim kho, txo tus nqi tsim kho.
2. Nrog rau cov dej siab siab, tsis kam mus rau sab nraud load thiab hloov mus rau qhov kev hloov ntawm geological tej yam kev mob, cov yeeb nkab muaj qhov zoo ntawm lub zog siab, zoo toughness, corrosion kuj, saj zawg zog interface yooj yim installation, muaj zog seismic tsis kam, tsis tshua muaj zog siv, yuav siv tau rau lub geological tsis zoo seem thiab hla txoj kev loj, tsis muaj ntxiv ua ntawm steel yeeb nkab, ua ke nrog muaj zog corrosion kuj, muaj peev xwm siv tau rau cov ntug hiav txwv dej. Tam sim no, nws yog dav siv nyob rau hauv underground pipeline engineering. Cov kav dej loj loj tuaj yeem cuam tshuam nws qhov zoo ntawm kev teeb tsa yooj yim thiab kev siv zog tsawg.
3. Cov yeeb nkab nodular cam khwb cia hlau muaj kev sib khi zoo thiab tsis yooj yim rau xau, uas tuaj yeem txo qhov xau ntawm cov yeeb nkab network thiab txo cov nqi tu txhua hnub ntawm cov yeeb nkab network.
Graphite nyob rau hauv nodular cam khwb cia hlau yog nyob rau hauv spherical daim ntawv. Qhov loj ntawm graphite yog 6 ~ 7. Hais txog qhov zoo, qib spheroidization ntawm nodular cam khwb cia hlau yeeb nkab yuav tsum tau tswj raws li 1 ~ 3 qib spheroidization tus nqi >. = 80%. Yog li ntawd, cov khoom siv kho tshuab tau zoo dua tuaj. Cov kav hlau kav hlau manufacturers hais tias tom qab annealing ductile hlau yeeb nkab, cov qauv metallographic yog ferritic nrog me me ntawm tswm ciab. Zoo mechanical zog.
