Iintambo zocingo lwentsimbi engenastainless zinamandla aphezulu ngokungaqhelekanga, zifaneleka njengeemveliso zequintessential 'eziphezulu{0}}eziphezulu'. Ukwenza umzekelo, umsonto omnye wentambo yentsimbi engatyiwayo engama-304, malunga nomnwe{3}}ongqindilili (malunga ne-10mm), unokumelana nowona mthwalo uphezulu wokuqhawuka odlula iitoni ezintlanu. Nangona kunjalo, amandla eentambo zensimbi engenasici ayiloxabiso elimiselweyo kodwa kunoluhlu, olugqitywe ngokuyintloko ngebakala lezinto eziphathekayo, uyilo lwesakhiwo kunye nobubanzi.
Imigangatho eyahlukeneyo yensimbi engenasici inokwakheka kweekhemikhali ezahlukeneyo kunye neempawu ezahlukeneyo zoomatshini.
| Ibanga lamandla (eliqhelekileyo) | Uluhlu lwamandla okuqina (MPa) | Iimpawu kunye neemeko zeSicelo |
| Austenitic 304 | 500 - 700 iMPa | Ukuchasana nokugqwesa okugqwesileyo, amandla aphakathi, alungele indawo emanzi / yeekhemikhali (usetyenziso lwaselwandle, uhombiso lwangaphandle) |
| I-Austenitic 316 | 500 - 700 iMPa | Iqulathe i-molybdenum, inika ukuxhathisa okongeziweyo kukonakala kwamanzi olwandle kwaye iqeshwe kubunjineli baselwandle kunye{0}}nofakelo oluphezulu lwangaphandle. |
| Phezulu{0}}amandla eMartensite | 1000 - 1400 iMPa | Amandla omelezwa ngonyango lobushushu, nangona ukuxhathisa umhlwa kuncitshiswe kancinci. Ifanelekile kumthwalo womatshini -ukuthwala kunye nokufakwa kwimizi-mveliso yokuphakamisa |
Ubume bentambo yeentambo zentsimbi ngokunjalo kugqiba amandla azo okugqibela.
Okukhona inani leentambo, ngcono ukuguquguquka; nangona kunjalo, kwidayamitha enikiweyo, ucingo lomntu ngamnye luba ngcono.
Iintambo zocingo ezinoqhagamshelwano lwelayini zibonisa ulwakhiwo oludityanisiweyo ngakumbi kunezo zinendawo yokudibana, okukhokelela kuxinzelelo oluphantsi loqhagamshelwano phakathi kweengcingo. Ngenxa yoko, babonisa amandla amakhulu kunye nobomi obude benkonzo.
Ukuphinda-phinda idiamitha → Kuqikelelwa ngokuphindwe kathathu okanye kane amandla okuqhawuka (ukusondela kubudlelwane obusisikwere).
Umzekelo: Intambo yentsimbi engatyiwayo engama-304 enobubanzi obuyi-3mm inamandla okuqhawuka aqikelelwa malunga neetoni ezi-4-5; intambo yobubanzi obuyi-10mm inokufikelela kwiitoni ezingama-40-50.
Iingcebiso zoKhetho lweModeli
Iintambo zensimbi ezingenasici zamandla afanelekileyo zinokukhethwa ngokweemeko ezithile zesicelo.
Ukukhuselwa komhlwa okusemgangathweni + umthwalo ophakathi → 304 intsimbi engatyiwa (ixabiso eliphezulu{2}}ukusebenza).
Imekobume yaselwandle/yekhemikhali → 316 intsimbi engatyiwayo (ukuxhathisa umhlwa kuqala).
Ultra -iimfuno zamandla aphezulu → Intsimbi ye-Martensitic (ifuna amanyathelo okuthintela umhlwa).
Ukugoba rhoqo okuguquguqukayo → Khetha isakhiwo esinenani eliphezulu leengcingo (umzekelo, 7×19) kwaye wandise umba wokhuseleko.
Ngokuqhelekileyo, amandla eentambo zensimbi ezingenasici zidibana ngokupheleleyo, kwaye zigqithise, iimfuno zobuninzi bezicelo zoshishino kunye nemihla ngemihla. Xa ukhetha imveliso ethile yeprojekthi, eyona ndlela ithembekileyo kukudibana nesatifikethi soqinisekiso lomgangatho wemveliso, esichaza ngokucacileyo amandla okuzinza (MPa) kunye namandla okuqhawula amancinane (kN/tonne). Esi sesona siseko sichanekileyo sokhetho.
