Njengoko imfuno yezinto zombhobho kwicandelo lemizi-mveliso iphucuka ngakumbi, ukuthandwa kweepayipi ezingenamthungo kunye neepayipi ezidityanisiweyo kuyaqhubeka nokunyuka. Eli nqaku liza kuhlalutya ngokubanzi ngokwembono yokwakheka kwezinto, iingenelo eziphambili, iindlela zokwahlulahlula kunye neendawo ezifanelekileyo, kwaye lidibanise amagama angundoqo okukhangela ashushu athi "ukukhethwa kwezinto zombhobho ezinoxinzelelo oluphezulu" kunye "nezinto zokwakha ezingabizi kakhulu" ukubonelela ngereferensi yokuthengwa kobunjineli.
1. Ukwakheka kwezinto
Umbhobho ongenamthungo
Izinto eziphambili: intsimbi yekhabhoni esemgangathweni ophezulu (njengentsimbi engama-20, intsimbi engama-35), intsimbi ye-alloy (njenge-16Mn, i-40Cr), intsimbi engatyiwayo (304/316L) kunye nentsimbi yebhoyila (20g)
Iimpawu: akukho zi-welds, ukwakheka okufanayo, kufanelekile kwiimeko zobushushu obuphezulu kunye noxinzelelo oluphezulu.
Umbhobho odibeneyo
Izinto eziphambili: intsimbi ekhabhoni ephantsi (Q235), intsimbi edibeneyo ephantsi (L290, L360), intsimbi egayiweyo kunye nentsimbi engagqwaliyo
Iimpawu: zenziwe ngokuwelda iipleyiti zentsimbi, ixabiso eliphantsi kunye neenkcukacha eziguquguqukayo.
2. Uthelekiso lweenzuzo eziphambili
Udidi Iingenelo zepayipi ezingenamthungo Iingenelo zepayipi edibeneyo
Amandla Amandla aphezulu ngokubanzi, ukumelana noxinzelelo olungaphezulu kwe-415MPa16 Amandla okuwelda aphantsi kancinci, kodwa anokuhlangabezana neemfuno zoxinzelelo oluphantsi
Inkqubo Akukho zidityanisiweyo, thintela umngcipheko wokuvuza15 Ukusebenza kakuhle kwemveliso, iindleko eziphantsi ngama-30%-50%
Inkangeleko Umphezulu othambileyo, akukho zimpawu zokucubungula3 Ii-welds zikho, unyango lomphezulu luyadingeka ukuphucula inkangeleko6
Ukusetyenziswa Ioyile negesi enoxinzelelo oluphezulu, amandla enyukliya, oomatshini abachanekileyo5 Izakhiwo zezakhiwo, ubunjineli bukamasipala, ukunkcenkceshela kwezolimo
3. Amanyathelo ama-4 okwahlula imibhobho engenamthungo kwimibhobho edibeneyo
Qaphela ukuwelda: iimpawu zokuwelda ezithe tye zinokubonakala kwiindonga zangaphakathi nezangaphandle zombhobho oweldingweyo, kwaye umbhobho ongenamthungo awunamthungo
Amandla ovavanyo: imibhobho engenamthungo inokumelana novavanyo loxinzelelo lwamanzi oluphezulu (njengoko lungaphezulu kwe-30MPa)
Hlalutya icandelo elinqamlezileyo: umbhobho ongenamthungo unecandelo elinqamlezileyo elifanayo, kwaye umbhobho odibeneyo unokuba nomahluko omncinci wobukhulu ngenxa yokudityaniswa
Jonga isatifikethi: iipayipi ezingenamthungo kufuneka zinike iingxelo zokufumanisa iziphene zezinto, kwaye iipayipi ezihlanganisiweyo zigxile kwisiqinisekiso somgangatho wokudityaniswa
4. Iimeko zesicelo ezicetyiswayo
Imibhobho engenamthungo:
Ioyile kunye negesi yendalo: imibhobho yokudlulisa uxinzelelo oluphezulu (udidi lwentsimbi ye-X60/X70)
Amandla kunye namandla: imibhobho yebhoyila, iinkqubo zokupholisa amandla enyukliya
Imveliso ephezulu: iipayipi ze-hydraulic zeenqwelo moya, iishafts zokuqhuba iimoto
Umbhobho odibeneyo:
Ubunjineli bokwakha: isakhelo sesakhiwo sentsimbi, i-scaffolding
Indlela yokuphila kamasipala: uthungelwano lwamanzi kunye nemibhobho yamanzi, inkqubo ye-HVAC
Ezolimo kunye noshishino: imibhobho yokunkcenkceshela, iishelufu zokugcina izinto
V. Jindalai Steel: Isisombululo sepayipi enye
Ngenxa yokukhangela okushushu kwakutshanje “kobonelelo olufumanekayo” kunye “neepayipi ezingabizi kakhulu”, iJindalai Steel Company ibe lukhetho lokuqala kushishino olunezi nzuzo zilandelayo:
Iindidi ezipheleleyo: ezigubungela intsimbi yekhabhoni, intsimbi ye-alloy, imibhobho engenamthungo yentsimbi engatyiwayo kunye nemibhobho edibeneyo, exhasa ubungakanani obungengomgangatho obenzelwe wena
Inzuzo yexabiso: imveliso enkulu inciphisa iindleko, kwaye ixabiso leyunithi yeepayipi ezidityanisiweyo liphantsi nge-10% kunemarike.
Uqinisekiso lomgangatho: bonelela ngeengxelo zohlolo lomntu wesithathu (ezifana ne-SGS, i-BV), ngokuhambelana ne-GB/T 3091, i-GB/T 9711 kunye neminye imigangatho yesizwe
Impendulo ekhawulezileyo: iitoni ezingama-5,000 zezinto ezisetyenzisiweyo
Isiphelo
Nokuba yimibhobho engenamthungo phantsi kweemeko zoxinzelelo oluphezulu okanye imibhobho edityanisiweyo engabizi kakhulu nesebenzayo, ukukhetha izinto ezifanelekileyo kunokwandisa iingenelo zeprojekthi. IJindalai Steel, eneteknoloji njengenkxaso kunye nenkonzo njengeyona nto iphambili, inika abathengi behlabathi izisombululo zemibhobho ezingabizi kakhulu ukunceda iiprojekthi zifike ngokufanelekileyo!
