Zas Hlau Kav Hlauyog ntawm kev ua tau zoo dua li dog dig hlau kav hlau. Cov teeb meem hauv cov hlau cam khwb cia yog nyob rau hauv cov ntawv txheeb thiab muaj zog tsawg. Yog li dog dig hlau lub zog yog qhov tsawg, nkig. Cov teeb meem hauv graphite pov cov hlau yog spherical, sib npaug rau lub hav zoov ntawm ntau lub kheej kheej hauv cov hlau cam. Cawv ntawm spherical voids ntawm lub zog ntawm cam khwb cia hlau yog ntau dua li ntawm cigile cov yeeb nkab yog ntau dua li cov hlau cam khwb cia.
Qhov zoo ntawm cov quav hlau yeeb ntaub ntawv thov hauv cov dej xa dej:
1. Vim tias cov yeeb nkab hlau nplaum adstile
2. Nrog dej siab tso dej siab, tsis kam mus rau seem tsis zoo, muaj peev xwm ua tau zoo dua qub, tuaj yeem siv rau cov ntug dej tsis yeem, tuaj yeem siv rau cov ntug hiav txwv thiab cov dej qab zib-alkali. Ntawm tam sim no, nws yog dav siv nyob rau hauv av xa hluav taws engineering engineering. Cov hauj lwm loj hluav taws xob hluav taws xob teeb hluav taws xob tuaj yeem cuam tshuam nws qhov zoo ntawm kev teeb tsa yooj yim thiab kev siv zog.
3. Tus nodular cam khwb cia hlau yeeb tau muaj kev sib tw zoo thiab tsis yooj yim kom muaj cov kav dej xau thiab txo cov kev lag luam txhua hnub ntawm cov yeeb nkab.
Graphite hauv nodular cam khwb cia hlau yog nyob rau hauv spherical form. Qhov loj ntawm graphite yog 6 ~ 7. Hais txog qhov zoo, SpHeroidolation Qib ntawm nodular cam steel yeeb nkab yuav tsum tau tswj hwm raws li 1 ~ 3 qib kev sib tw>. = 80%. Yog li ntawd, cov cuab yeej ua haujlwm tau zoo dua. Zas cov tshuab yeeb nkab kws tsim khoom lag luam hais tias tom qab annealing ductile hlau yeeb nkab yog ferritic nrog ib tug me me ntawm kev sib txuas. Cov khoom siv zoo.
