Nodular cam khwb cia hlau yeeb nkab
Nodular cam khwb cia hlau steel kav yog qhov tseem ceeb ntawm cov kav hlau, uas muaj cov ntsiab lus ntawm cov hlau thiab cov khoom ntawm cov hlau, yog li lawv lub npe. Graphite nyob rau hauv ductile hlau kav muaj nyob rau hauv ib tug kheej kheej daim ntawv, nrog ib tug dav dav ntawm 6-7 qib. Nyob rau hauv cov nqe lus ntawm zoo, spheroidization theem ntawm cam khwb cia hlau kav yuav tsum tau tswj nyob rau hauv 1-3 theem, nrog ib tug spheroidization tus nqi ntawm ≥ 80%. Yog li ntawd, cov khoom siv ntawm cov khoom siv nws tus kheej tau txhim kho, muaj cov ntsiab lus ntawm cov hlau thiab cov khoom ntawm cov hlau. Tom qab annealing, lub microstructure ntawm cov kav hlau hlau yog ferrite nrog ib qho me me ntawm pearlite, uas muaj cov khoom siv zoo, yog li nws tseem hu ua cam khwb cia hlau steel kav.
