Ingcingo yensimbi engenasiphene yimathiriyeli eguquguqukayo esetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokuqina kwayo, ukumelana nokubola kunye namandla aphezulu okuqina.Ukuqonda inkqubo yokwenziwa kocingo lwensimbi engenasici ukusuka kwinqanaba lezinto eziluhlaza ukuya kwimveliso egqityiweyo kubalulekile.Eli nqaku liza kunika isingeniso esinzulu kwindlela yokuvelisa ucingo lwensimbi engenasici kunye neteknoloji yokucubungula ebandakanyekayo kwinkqubo yokuvelisa.
Uhambo lokuvelisa ucingo lwensimbi engenasici luqala ngokukhethwa kwezinto ezibonakalayo.Inxalenye ephambili yocingo lwensimbi engenasici i-chromium, eyandisa ukuxhatshazwa kwe-corrosion yemveliso yokugqibela.Ukongezelela, ezinye izinto ezifana ne-nickel, i-carbon kunye ne-manganese zongezwa ukuphucula iimpawu ezithile zocingo, njengamandla kunye nokubumba.Ezi zixhobo eziluhlaza zilinganiswa ngononophelo kwaye zidibaniswe ngokwemilinganiselo echanekileyo ukufezekisa iimpawu ezifunwayo.
Nje ukuba izinto ezikrwada zidityanisiwe, ziya kunyibilika.Umxube ushushu kwindawo elawulwa kakhulu, ngokuqhelekileyo kwisithando somlilo sombane.Njengoko iqondo lokushisa liphakama, izinto eziluhlaza ziyanyibilika kwaye zenze i-alloy yensimbi engenasici.Isinyithi esinyibilikisiweyo esingenasici sigalelwa kumngundo ukwenza iimveliso ezigqityiweyo ezifana neebhilidi okanye iingots.
Isinyathelo esilandelayo kwinkqubo yokuvelisa i-hot rolling ye-semi-finished product.I-billet okanye i-ingot iyafudumala kwaye idluliselwe kwiichungechunge ze-roller, ngokuthe ngcembe inciphisa ubukhulu bayo.Inkqubo yokufudumala eshushu inceda ukucokisa isakhiwo sengqolowa yensimbi engenasici kunye nokuphucula iimpawu zayo zomatshini.Ukuncitshiswa kobungqingqwa okuphunyezwe ngexesha lokuqengqeleka okushushu kubalulekile ukuze kufumaneke i-diameter yentsimbi engenasici efunwayo.
Emva kokuqengqeleka okushushu, intsimbi engenastainless idlula kwinkqubo ebizwa ngokuba yi-annealing.I-Anealing kukufudumeza ucingo lwensimbi engenasici kwiqondo lobushushu elithile kwaye uyigcine kangangexesha elimiselweyo.Le nkqubo ikhulula uxinzelelo lwangaphakathi, ukuthambisa izinto kunye nokwenza kube lula.I-Anealing iphinda ihlambulule isakhiwo se-crystal kwaye siphucule ukucwangciswa kunye nokuqulunqwa kocingo.
Emva kokuba i-annealing, ucingo lwensimbi engenasici lulungele umzobo obandayo.Umzobo obandayo ubandakanya ukuzoba ucingo ngoluhlu lokufa ukunciphisa kancinci ubukhulu bayo kunye nokwandisa ubude bayo.Inkqubo iphinda iphucule ukugqitywa komphezulu wocingo, isuse nayiphi na intsalela yoxinzelelo lwangaphakathi kwaye iphucule ngakumbi iimpawu zayo zomatshini.Ucingo lwensimbi engenasici lunokutsalwa amaxesha amaninzi ukufezekisa i-diameter efunekayo, ukuqinisekisa ukuhambelana kunye nomgangatho.
Isinyathelo sokugqibela kwinkqubo yokuvelisa unyango olungaphezulu.Ucingo lwensimbi engenasici luhlala lufuna unyango olungaphezulu olufana nokuchola, ukunyanzeliswa okanye iinkqubo zokugquma, kuxhomekeke kwisicelo sayo.I-Pickling ibandakanya ukususa isikali okanye ukungcola kumphezulu wocingo, ngelixa i-passivation idala umaleko obhityileyo we-oxide okhulisa ukuxhathisa ukubola.Iinkqubo zokugquma ezifana ne-electroplating okanye i-galvanizing zingasetyenziselwa ukubonelela ngokhuseleko olongezelelweyo okanye ukuphucula ukubonakala kocingo.
