Ukuboniswa okuyingxenye kwemikhiqizo yenkampani

Ngokuthuthukiswa kwesayensi nobuchwepheshe, ukusetshenziswa kwesakhiwo sensimbi kubunjiniyela bokwakha kuya ngokuya kwanda emhlabeni. I-Welding ubuchwepheshe bokucubungula obubaluleke kakhulu ekwakhiweni kwesakhiwo sensimbi.Ngokusho kwezibalo zamazwe athuthukile ezimbonini, kuphela insimbi esetshenziswe ngemuva kokushisela ithatha cishe u-45% wokukhishwa kwensimbi minyaka yonke.China kuze kube sekupheleni kweminyaka yama-1980, isakhiwo sensimbi esishiselwe ine-30% yomkhiqizo wensimbi.

Ngo-1992, ukukhishwa kwensimbi yaseChina kwakungamathani ayizigidi ezingama-80, kodwa ekupheleni kuka-1997, ukukhishwa kwensimbi yaseChina kwase kufinyelele kumathani ayizigidi ezingama-94. Ngokwenkambiso yentuthuko, ukukhishwa kwensimbi yaseChina kungekudala kuzodabula amathani ayizigidi eziyi-100 ngemuva kokungena ekhulwini elisha.

Izici zensimbi

Okokushisa okushisayo okushisayo (i-Angle steel, i-steel, ishaneli yensimbi, ishubhu yensimbi, njll., Ukwakha insimbi encane yodonga, ipuleti lensimbi, intambo ebandayo nentambo njengengxenye eyisisekelo, ngokuxhuma nge-welding, bolt noma rivet, ngokusho imithetho ethile yokuxhuma kumabhuloki wokwakha ayisisekelo, angajwayelekile ngokushisela, ibhawodi noma ukuxhumeka kwe-rivet ukuxhuma amabhlogo ayisisekelo esakhiweni njengesakhiwo sensimbi ukumelana nomthwalo.

Amandla amakhulu nobukhulu obuncane. Amandla wensimbi aphakeme kaningi kunalawo wokhuni, izitini namatshe, ukhonkolo nezinye izinto zokwakha. Ngakho-ke, lapho umthwalo nezimo zifana, isakhiwo esenziwe ngensimbi sinesisindo esincane esifile, izingxenye ezincane ziyadingeka, futhi sikulungele kakhulu ukuthuthwa nokwakhiwa.

(2) Ubupulasitiki obuhle nobulukhuni.Steel ine-plasticity enhle, ngokuvamile, ngeke ibe ngenxa yokugcwala ngokweqile noma ngokweqile kwendawo okubangelwa ukwehluleka okungazelelwe kokuqhekeka, kepha izovela ngaphambi kokuguqulwa okukhulu kwe-omen, ukuze kuthathwe izinyathelo zokulungisa Insimbi ibuye ibe nokuqina okuhle nokuzivumelanisa nezimo okuqinile kumthwalo onamandla osebenza esakhiweni, esihlinzeka ngesiqinisekiso esithembekile sokusetshenziswa okuphephile kwesakhiwo sensimbi.

Ukwakheka kwangaphakathi kwensimbi kufana, izakhiwo ezibonakalayo nezomshini zazo zonke izinkomba ngokufanayo ziyafana, zisondelene kakhulu nomzimba we-isotropic, ngaphakathi kohlobo oluthile lokucindezeleka, insimbi esesimweni esihle sokunwebeka, kanye nesisekelo ukucabanga okusetshenziswe yimishini yobunjiniyela kuyavumelana kakhulu, ngakho imiphumela yokubala inembile futhi ithembekile.

Isakhiwo sensimbi sakhiwe izigaba ezahlukahlukene ezicutshungulwayo kanye namapuleti wensimbi, enziwa ngezinto eziyisisekelo ngokusebenzisa i-welding, i-bolt noma i-rivet uxhumano, bese ithunyelwa esizeni ukuze ihlangane futhi i-splicing.Ngakho-ke, ukwenziwa kulula , umjikelezo wohlelo lokusebenza mfushane, ukusebenza kahle kuphezulu, futhi ukulungisa, ukufaka esikhundleni nakho futhi kuyindlela elula.Le ndlela yokwakha yokukhiqiza ifektri nokufakwa kwesayithi inezinzuzo zokukhiqizwa kweqoqo elikhulu nokunemba okuphezulu kwemikhiqizo eqediwe, futhi idale izimo zokunciphisa kubiza futhi kuletha inzuzo yezomnotho yotshalo-mali

(5) Isakhiwo sensimbi esinezinsimbi kulula ukugqwala emoyeni, ikakhulukazi kumswakama noma ukugqwala okusheshisiwe ukugqwala okuphakathi, ngakho-ke kaningi kudinga ukulungiswa nokugcinwa, okufana nokugqwala, ukumboza, njll. phezulu.

Izinga eliphansi lokushisa ukumelana.Steel ayikwazi ukumelana nokushisa okuphezulu, ngokukhuphuka kwezinga lokushisa, amandla wensimbi azokwehla.Komlilo, isakhiwo sensimbi ngaphandle kokuvikelwa singagcinwa kuphela cishe ngama-20min, ngakho-ke isakhiwo sensimbi esibalulekile kufanele sinake thatha izinyathelo zokuvimbela umlilo, njengasesakhiweni sensimbi ngaphandle kukakhonkolo wesinkwa noma ezinye izinto zomlilo, noma ukufafaza umlilo wokumboza ebusweni bezinto.

Ukuboniswa kwemikhiqizo eqediwe ngaphambi kokudweba kuqediwe ngokuya ngenombolo yokudweba. Inombolo ikhombisa ukuthi izingxenye ezingadwetshiwe zilethwa ngokulandelana kwenombolo, akukhathalekile ukuthi kuthuthwa noma kufakwa kanjani
