Zopangira Zitsulo za Sitima

Zofunika za gawo lachinyengo ili:

14CrNi3MoV (921D), yoyenera kupangira zitsulo ndi makulidwe osapitirira 130mm omwe amagwiritsidwa ntchito m'zombo.

Njira yopanga:

Chitsulo chopukutira chiyenera kusungunuka pogwiritsa ntchito ng'anjo yamagetsi ndi njira yamagetsi ya slag remelting, kapena njira zina zovomerezeka ndi mbali yofunikira.Chitsulocho chiyenera kukhala ndi deoxidation yokwanira komanso njira zoyeretsera mbewu.Popanga ingot molunjika ku gawo lopangidwa, chiŵerengero cha kupanga cha gawo lalikulu la gawolo chiyenera kukhala chosachepera 3.0.Kupanga chiŵerengero cha magawo athyathyathya, ma flanges, ndi magawo ena owonjezera a gawo lopangidwa sikuyenera kukhala osachepera 1.5.Popanga billet kukhala gawo lopukutidwa, chiŵerengero cha kupangika kwa thupi lalikulu la gawolo sichiyenera kukhala chochepera 1.5, ndipo chiŵerengero cha zigawo zotuluka chiyenera kukhala zosachepera 1.3.Ziwalo zopukutira zopangidwa ndi ma ingot kapena ma billet abodza ziyenera kupangidwa ndi dehydrogenation yokwanira ndi chithandizo cha annealing.Kuwotcherera ma billets achitsulo omwe amagwiritsidwa ntchito popanga zida zopukutira sikuloledwa.

Mkhalidwe wotumizira:

Gawo lopukutidwa liyenera kuperekedwa mozimitsidwa ndi kupsya mtima pambuyo pokonzekera chithandizo chisanachitike.Njira yovomerezeka ndi (890-910) ° C normalizing + (860-880) ° C quenching + (620-630) ° C kutentha.Ngati makulidwe a gawo lopukutidwa ndi 130mm, liyenera kutenthedwa pambuyo pokonza movutikira.Ziwalo zopindika zopindika siziyenera kuthana ndi nkhawa popanda chilolezo cha mbali yofunikira.

Makaniko katundu:

Pambuyo tempering mankhwala, mawotchi zimatha gawo lopukutira ayenera kutsatira mfundo zofunika.Mayeso ocheperako pa kutentha kwa -20°C, -40°C, -60°C, -80°C, ndi -100°C akuyenera kuchitidwa, ndipo mapindikidwe a kutentha kwa mphamvu akuyenera kulinganizidwa.

Zosakaniza zopanda zitsulo ndi kukula kwambewu:

Magawo opangidwa kuchokera ku ingot ayenera kukhala ndi kukula kwambewu osati kokulirapo kuposa 5.0.Mlingo wamtundu wa A inclusions muzitsulo sayenera kupitirira 1.5, ndipo mlingo wa R mtundu wa inclusions sayenera kupitirira 2.5, ndi chiwerengero cha zonse zosapitirira 3.5.

Ubwino wapamwamba:

Zigawo zopukutira siziyenera kukhala ndi zilema zowoneka bwino monga ming'alu, zopindika, ming'alu, zipsera, kapena zina zopanda chitsulo.Zowonongeka zapamtunda zimatha kukonzedwa pogwiritsa ntchito kukwapula, kupukuta, kugaya ndi gudumu lopera, kapena njira zopangira makina, kuwonetsetsa kuti pali mwayi wokwanira kumaliza pambuyo pokonzanso.
