Ductile hlau yeeb nkab yog ib hom cam khwb cia hlau yeeb nkab.Cov kev cai zoo ntawm cam khwb cia hlau yeeb nkab spheroidization qib tswj rau 1-3 (spheroidization tus nqi "80%), yog li cov khoom siv ntawm cov khoom nws tus kheej tau zoo dua qub, nrog rau qhov zoo ntawm cov hlau, steel kev ua tau zoo.Annealed ductile hlau yeeb nkab, nws metallographic qauv yog ferrite thiab ib tug me me ntawm pearlite, zoo mechanical zog, zoo heev corrosion kuj, zoo ductility, zoo sealing nyhuv, yooj yim rau nruab, feem ntau yog siv rau hauv nroog, industrial thiab mining lag luam dej, roj, roj thiab lwm yam.
Ib qho nyiaj ntawm spherical graphite yog faib rau ntawm ferrite thiab pearlite matrix.Raws li cov kev cai ntawm nominal txoj kab uas hla thiab elongation, qhov kev faib ua feem ntawm ferrite thiab pearlite nyob rau hauv lub matrix yog txawv.Qhov feem ntawm pearlite nyob rau hauv me me txoj kab uas hla yog feem ntau tsis ntau tshaj 20%, thiab hais tias nyob rau hauv loj txoj kab uas hla yog feem ntau tswj ntawm txog 25%.
Nws muaj cov yam ntxwv ntawm hlau, kev ua tau zoo ntawm cov hlau, zoo heev anticorrosion kev ua tau zoo, zoo ductility, zoo sealing nyhuv, yooj yim rau nruab, feem ntau yog siv rau hauv nroog, industrial thiab mining lag luam dej, roj, roj thiab lwm yam.Nws yog thawj qhov kev xaiv ntawm cov kav dej, nrog rau kev ua haujlwm siab.Piv nrog PE yeeb nkab, los ntawm lub sij hawm installation, lub installation ntawm kheej kheej number case yeeb nkab yog yooj yim dua thiab sai dua PE yeeb nkab, thiab lub siab sab hauv thiab sab nraud yog zoo dua tom qab installation;Los ntawm airtight thiab anticorrosive taw tes ntawm view, tom qab lub installation ntawm spherical number case raj airtight yog zoo dua, tab sis kuj los ntawm ntau yam anticorrosive txhais tau tias los txhim kho corrosion kuj;Nyob rau hauv cov nqe lus ntawm hydraulic kev ua tau zoo, cov specifications ntawm spheroidal number case raj feem ntau xa mus rau lub puab txoj kab uas hla, thiab cov specifications ntawm PE raj feem ntau xa mus rau lub sab nraud txoj kab uas hla, vim hais tias nyob rau hauv tib lub specifications, lub spheroidal number case raj muaj peev xwm ua tau ntau dua ntws;Los ntawm kev txhim kho thiab kev saib xyuas tus nqi ntawm qhov pom, spheroidal number case tube muaj cov nqi zoo dua.Sab hauv phab ntsa txau zinc, cement mortar anti-corrosion cov ntaub ntawv.
