Kodi machubu a square-strength ndi chiyani?

Makhalidwe amachitidwe achubu lalikulu lamphamvu lalikulundi mphamvu zambiri, kulimba kwabwino komanso kukana mphamvu.
Mphamvu: mfundo zokolola (σ s)≥390mpa;
Kukhazikika kwamphamvu (b b)≥635mpa;
elongation δ 5 (%)≥25;
Kuuma hb ≤ 187hv,
Kutentha mankhwala specifications: normalizing 850 ° C;kutentha kwa 880 ° C;Kutentha kwa 600 ° C.
Zida: zopangidwa mwapamwamba kwambiricarbon structural chitsulondi kugudubuza kotentha kapena kujambula kozizira.
Kagwiritsidwe: ntchito popanga madzi utakhazikika chitoliro pakhoma, madzi otentha chitoliro, locomotive madzi thanki nthunzi chitoliro ndi arch njerwa chitoliro, etc.
Mafotokozedwe ndi maonekedwe abwino:
Gulu lililonse lamapaipi achitsuloaziyang'aniridwa chimodzi ndi chimodzi, ndipo pamwamba pake pasakhale ming'alu, zopindika ndi zopindika pakhungu;Akupanga cholakwa kudziwika adzakhala kuchitikira aliyense zitsulo chitoliro kuyendera makina zimatha weld.Nthawi zambiri, kotalika kotalikirana kowonjezera kowotcherera ndi 0.2-0.25mm, kutalika kolimbikitsira m'mimba mwake kwa circumferential weld ndi 0.75-1mm, ndi kulimbikitsa kotenga nthawi yayitali pazitsulo sikuyenera kuchepera 0.25mm
Kapangidwe ka mankhwala Kapangidwe kazinthu zomalizidwa kumagwirizana ndi zomwe GB 222-84.
Zakuthupi ndi zamakina:
1) Mzere wokhotakhota wokhotakhota woyeserera uzikhala wathyathyathya popanda kusintha mwadzidzidzi
2) Kuyesa kwamphamvu Kutentha kotsika kwachitsanzo kumayesedwa ndi njira yoyesera yopendekera pa kutentha komwe kwatchulidwa.
3) Ming'alu siziloledwa pamapaipi omwe amawotchedwa ndi zida za hydraulic kapena pneumatic
4) Kupanikizika kosafanana kwa mayeso opindika sikudutsa mtengo womwe watchulidwa.
Mayendedwe a njira: Mzere wachitsulo ukangolumikizidwa kukhala kawonekedwe kakang'ono ka disc ndikupangidwa mosalekeza, umayendetsedwa ndi njira yowotcherera yokhala ndi ma pass-multi-pass, kenako ndikulowa mugawo lowotcherera kwambiri.Malekezero awiriwa amalumikizidwa ndi chowotcherera chapamwamba kwambiri kuti apange chowotcherera chozungulira.Pambuyo kuwotcherera, chitoliro chachitsulo chimakula ndikudulidwa ndi kukula ndi kudula.Potsirizira pake, chitoliro chachitsulo chimazimitsidwa ndi kutenthedwa ndi gawo lomaliza, ndiyeno kupopera ndi primer kuti amalize kupanga.
