Hlau logyog ib hom ntawm lub log ua los ntawm hlau thiab hlau, thiab nws tseem yog cov khoom siv tsheb siv thaum ntxov, uas muaj cov yam ntxwv ntawm tus nqi qis, siab zog, zoo hnav tsis kam thiab kev siv tshuab yooj yim, nws tseem siv dav hauv txhua yam. niaj hnub qis-kawg tsheb thiab tsheb thauj khoom.Nws qhov tsis zoo tseem ceeb yog qhov ua tau zoo thiab tsis zoo nkauj.Qhov kev xaiv tseem ceeb ntawm cov ntaub ntawv steel log yog carbon steel, ductile hlau, lwm yam ntaub ntawv steel.Feem ntau ntawm cov pa roj carbon steel log yog siv nyob rau hauv dav dav lub zog kev ua tau zoo tsheb, nws tsis muaj zog, tsis muaj zog tiv thaiv sab nraud quab yuam, nres thaum tshav kub kub ntawm lub tsheb kub dissipation kev ua tau zoo yog txwv, nws yog ib qho nyuaj rau cov txheej txheem zoo nkauj qauv ntawm cov pa roj carbon steel, tab sis nws tus nqi yog kev lag luam ntau dua, thiab nws yog thawj qhov kev xaiv rau ntau yam khoom siv hauv tsheb qis kawg.Ductile Iron Wheel muaj cov khoom siv zoo dua li cov roj carbon steel log, tab sis nws yog qhov nyuaj rau kev tswj cov duab ntau dua li carbon steel log thaum ua, yog li tus nqi ua haujlwm siab dua thiab kev lag luam tsis zoo.Nyob rau hauv xyoo tas los no, lwm cov ntaub ntawv hlau xws li qee cov hlau alloy steels tau siv ntau thiab ntau dua li cov khoom siv hauv tsheb, nws muaj qhov zoo ntawm lub zog ntau dua, sib dua qhov hnyav, zoo dua cov cua sov dissipation, ua haujlwm zoo thiab molding, yooj yim rau vuam thiab lwm yam, thiab tau txais kev pom zoo los ntawm feem ntau ntawm cov tsheb qhov chaw manufacturers.
