30CrMnSiA Thick Wall Alloy Steel Pipe

Kufotokozera Kwachidule:

Chitoliro chachitsulo cha 30CrMnSiA chili ndi mphamvu zambiri koma osagwira ntchito bwino.Pambuyo pa kutentha, imakhala ndi mphamvu zambiri komanso mphamvu zokwanira, ndipo imakhala ndi kuuma bwino.Pambuyo pozimitsa ndi kutenthetsa, ikhoza kupangidwa kukhala zitsulo zamagudumu, magiya, ndi sprockets.Ili ndi processability yabwino, mapindikidwe ocheperako, komanso kukana kutopa kwabwino.Amagwiritsidwa ntchito popangira ma shafts, zida zosinthira pisitoni, ndi zina zambiri. Amagwiritsidwa ntchito ngati zida zapadera zosamva kuvala zamagalimoto ndi ndege.

Katundu Wakuthupi

1. Mphamvu yayikulu ndi kulimba: Imakhala ndi mphamvu zokolola zabwino komanso kulimba kolimba, komanso kulimba kwamphamvu kwambiri.

2. Kukana kuvala bwino: Kulimba kwapamwamba kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'madera ovala kwambiri.

Kutentha Chithandizo Njira

Kuzimitsa: Kutentha kwa 880 ° C mpaka 920 ° C, kutsatiridwa ndi kuzizira kofulumira m'madzi kapena mafuta.

Kutentha: Kutenthetsa mpaka 200 ° C mpaka 500 ° C kuti mukwaniritse kulimba komwe mukufuna komanso kulimba.

Minda Yofunsira

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.

Mkhalidwe wotumizira

Amaperekedwa ndi chithandizo cha kutentha (normalizing, annealing kapena mkulu kutentha kutentha) kapena popanda kutentha kutentha.

Ili ndi mphamvu zambiri, koma ndi chitsulo chapakati-carbon chozimitsidwa komanso chosasunthika chokhala ndi kuuma kwakukulu, kotero ntchito yake yowotcherera ndiyosauka kwambiri.

Pambuyo pa kutentha, zinthuzo zimakhala ndi mphamvu zambiri komanso zolimba zokwanira, ndipo zimakhala ndi zovuta zabwino.Pambuyo pozimitsa ndi kutentha, zinthuzo zingagwiritsidwe ntchito ngati zitsulo zamagudumu, magiya, ndi sprockets.Pewani tsambalo ndi chodulira mphero ya carbide ndikupukuta ndi makina opukutira.Pasakhale vuto ngati roughness pamwamba kufika 3.2.Zinthu zake ndi zakuda kwambiri, ndipo kusonkhezera kumatha kupititsa patsogolo kukongola kwapamwamba komanso kupewa dzimbiri.
