Ubwino wa mipope yachitsulo ya ductile

Mapaipi achitsulondi abwino kwambiri kuposa mapaipi wamba chitsulo choponyedwa. Ma graphite mu chitsulo chonyezimira wamba ali m'mapepala ndipo ali ndi mphamvu zochepa kwambiri. Chifukwa chake mphamvu yachitsulo yotayidwa wamba ndi yochepa, yolimba. Chitsulo cha graphite chomwe chili mu chitsulo chopangidwa ndi graphite ndi chozungulira, chofanana ndi kukhalapo kwa zitsulo zambiri zozungulira muzitsulo zotayidwa. Mphamvu ya ozungulira opanda mphamvu ya chitsulo chosungunuka ndi yaying'ono kwambiri kuposa yopanda kanthu, kotero mphamvu ya chitoliro chachitsulo cha ductile ndipamwamba kwambiri kuposa yachitsulo choponyedwa wamba.

Ubwino wogwiritsa ntchito chitoliro chachitsulo cha ductile pamapaipi operekera madzi:

1. Chifukwa ductile chitsulo chitoliro utenga olowa kusinthasintha, ntchito yomanga ndi yabwino, akhoza kusintha ntchito yomanga, kusintha zinthu zomangamanga, kuchepetsa mtengo yomanga, ndi ambiri mawonekedwe utenga mphira mphete kugwirizana, ntchito yosavuta, akhoza kufupikitsa nthawi yomanga, kuchepetsa mtengo yomanga.

2. Ndi kuthamanga kwa madzi okwanira, kukana katundu wakunja ndi kusintha kwa kusintha kwa nyengo, chitolirocho chili ndi ubwino wa mphamvu zambiri, kulimba kwabwino, kukana dzimbiri, mawonekedwe osinthasintha, kukana kwamphamvu kwa seismic, kutsika kwa ntchito yotsika, kungagwiritsidwe ntchito ku gawo losauka la geological ndi kudutsa msewuwu, popanda processing yowonjezera ya zitsulo, kuphatikizapo kukana kwamphamvu kwa zoline-zokali. Pakalipano, amagwiritsidwa ntchito kwambiri mu engineering ya mapaipi apansi panthaka. Ntchito zoyika mapaipi akulu zitha kuwonetsa zabwino zake pakukhazikitsa kosavuta komanso kutsika kwantchito.

3. Chitoliro chachitsulo chokhala ndi nodular chili ndi ntchito yabwino yosindikiza ndipo sichophweka kutayikira, chomwe chingachepetse kutayikira kwa netiweki ya chitoliro ndikuchepetsa mtengo wokonza tsiku ndi tsiku wa network ya chitoliro.

Graphite mu nodular cast iron ali mu mawonekedwe ozungulira. Kukula kwa graphite ndi 6-7. Pankhani ya khalidwe, spheroidization kalasi ya nodular kuponyedwa chitsulo chitoliro ayenera kulamulidwa monga 1 ~ 3 kalasi spheroidization mlingo >. = 80%. Choncho, makina katundu bwino bwino. Opanga chitoliro chachitsulo cha ductile akuwonetsa kuti annealing ductile iron chitoliro, kapangidwe ka metallographic ndi ferritic ndi kandulo kakang'ono. Zabwino zamakina katundu.
