Mtengo Wochotsera 20CrNiMo Seamless Alloy Steel Pipe
Kufotokozera Kwachidule:
20CrNiMo ndi chitsulo chapamwamba kwambiri chopangidwa ndi aloyi chokhala ndi zida zabwino zamakina, kukana dzimbiri komanso kukana kuvala.Amagwiritsidwa ntchito kwambiri m'makina, uinjiniya, zomangamanga ndi zoteteza zachilengedwe.Mphamvu zake zapamwamba, kulimba kwabwino komanso ductility zimapangitsa kukhalabe ndi moyo wautali wautumiki m'malo ovuta komanso kupirira katundu wambiri, kupereka chithandizo champhamvu pakukula kwamakampani amakono ndi uinjiniya.
Pothandizidwa ndi gulu lotukuka kwambiri komanso laukadaulo la IT, titha kupereka chithandizo chaukadaulo pakugulitsa zisanachitike & ntchito zogulitsa pambuyo pa Mtengo Wochotsera 20CrNiMo Seamless Alloy Steel Pipe, Tiyesetsa kukhalabe ndi mbiri yabwino ngati opereka mayankho abwino kwambiri. pa dziko lapansi.Mukakhala ndi mafunso kapena malingaliro, onetsetsani kuti mwalumikizana nafe momasuka.
Pothandizidwa ndi gulu lotukuka kwambiri komanso laukadaulo la IT, titha kupereka chithandizo chaukadaulo pakugulitsa zisanachitike & ntchito zogulitsa pambuyo paChina 20CrNiMo Aloyi Yopanda Zitsulo Chitoliro, Kugwira ntchito molimbika kuti mupitilize kupita patsogolo, zatsopano mumakampani, yesetsani kuchita bizinesi yoyamba.Timayesa momwe tingathere kuti timange chitsanzo cha kasamalidwe ka sayansi, kuphunzira zambiri zamaluso, kupanga zida zapamwamba zopangira ndi kupanga, kupanga zinthu zoyambira kuitana, mtengo wololera, ntchito zapamwamba kwambiri, kutumiza mwachangu, kukupatsani kulenga. mtengo watsopano .

20CrNiMo poyamba inali chitsulo nambala 8620 mu American AISI ndi SAE miyezo.Ntchito yowuma ndi yofanana ndi yachitsulo cha 20CrNi.Ngakhale kuti Ni okhutira mu zitsulo ndi theka la 20CrNi zitsulo, chifukwa kuwonjezera pang'ono Mo element, kumtunda kwa austenite isothermal kusintha pamapindikira kumayenda kumanja;ndipo chifukwa cha kuwonjezeka koyenera kwa Mn okhutira, kuuma kwa chitsulo ichi kudakali kwabwino kwambiri, ndi mphamvu Imakhalanso yapamwamba kuposa zitsulo za 20CrNi, komanso imatha kusintha zitsulo za 12CrNi3 kupanga mbali za carburized ndi cyanide zomwe zimafuna ntchito yapamwamba kwambiri.20CrNiMo imatha kupirira kutentha kwina kuwonjezera pa zinthu zabwino zonse chifukwa ili ndi molybdenum.
1. M'makampani opanga zinthu, nthawi zambiri amagwiritsidwa ntchito popanga ziwalo zomwe zimakhala ndi katundu wambiri, kupanikizika kwambiri, komanso kuvala kwambiri, monga zida, shafts, bearings, etc. moyo wautali wautumiki m'malo ovuta kugwira ntchito.Kuphatikiza apo, ilinso ndi kukana kutopa kwambiri komanso kukana dzimbiri, zomwe zimatha kukana kukokoloka kwa chilengedwe chakunja ndikuwonetsetsa kuti zidazo zikugwira ntchito mokhazikika.
2. Pa ntchito yomanga, chitsulo ichi chimagwiritsidwa ntchito kwambiri pomanga nyumba zazikulu monga milatho ndi nyumba zapamwamba chifukwa cha mphamvu zake komanso ductility zabwino.M'mapangidwe awa, amatha kupirira kupanikizika kwakukulu ndi kupsinjika maganizo, kuonetsetsa chitetezo ndi kukhazikika kwa nyumbayo.
3. Kuonjezera apo, ndi kusintha kwa chidziwitso cha chilengedwe, ntchito zokhudzana ndi chitetezo cha chilengedwe zikuchulukirachulukira.Mwachitsanzo, m'magalimoto amagetsi atsopano, amatha kugwiritsidwa ntchito popanga zida zazikulu monga ma mota ndi zochepetsera, zomwe zimathandizira kuyenda kobiriwira.Zimagwiranso ntchito yofunika kwambiri pazida zotetezera zachilengedwe monga kuyeretsa zimbudzi ndi kutulutsa mpweya wotayirira, kupereka chithandizo champhamvu pakuwongolera chilengedwe.
1. Zida zomangira zofunikira, monga zida zoikira ndege, akasinja ndi zida zamagalimoto ankhondo.
2. Zomangira zamphamvu kwambiri ndi zolumikizira.
3. High katundu magiya ndi mayendedwe.
Kuzimitsa 850ºC, kuzizira kwamafuta;Kutentha kwa 200ºC, kuzizira kwa mpweya.
Kupereka chithandizo cha kutentha (normalizing, annealing kapena high heat tempering) kapena palibe kutentha kwa kutentha, chikhalidwe cha kubereka chiyenera kuwonetsedwa mu mgwirizano.
Pothandizidwa ndi gulu lotukuka kwambiri komanso la akatswiri, titha kupereka chithandizo chaukadaulo pakugulitsa zisanachitike & ntchito zogulitsa pambuyo pake.

Tiyesetsa kukhalabe ndi mbiri yabwino ngati opereka mayankho abwino kwambiri padziko lapansi.Mukakhala ndi mafunso kapena malingaliro, onetsetsani kuti mwalumikizana nafe momasuka.
China 20CrNiMo Aloyi Yopanda Zitsulo Chitoliro
Kugwira ntchito molimbika kuti mupitilize kupita patsogolo, zatsopano m'makampani, yesetsani kuchita bizinesi yoyamba.Timayesa momwe tingathere kuti timange chitsanzo cha kasamalidwe ka sayansi, kuphunzira zambiri zamaluso, kupanga zida zapamwamba zopangira ndi kupanga, kupanga zinthu zoyambira kuitana, mtengo wololera, ntchito zapamwamba kwambiri, kutumiza mwachangu, kukupatsani kulenga. mtengo watsopano .
