Ucingo lwentsimbi engagqwaliyo lusetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokuqina kwalo, ukumelana nokugqwala kunye namandla aphezulu okutsalwa. Kubalulekile ukuqonda inkqubo yokwenziwa kocingo lwentsimbi engagqwaliyo ukususela kwinqanaba lezinto eziluhlaza ukuya ekugqityweni kwemveliso. Eli nqaku liza kunika intshayelelo enzulu kwindlela yokwenziwa kocingo lwentsimbi engagqwaliyo kunye netekhnoloji yokucubungula ebandakanyekayo kwinkqubo yemveliso.
Uhambo lokwenziwa kwentambo yentsimbi engagqwali luqala ngokukhethwa kwezinto eziluhlaza. Icandelo eliphambili lentambo yentsimbi engagqwali yi-chromium, eyonyusa ukumelana nokugqwala kwemveliso yokugqibela. Ukongeza, ezinye izinto ezifana ne-nickel, ikhabhoni kunye ne-manganese zongezwa ukuphucula iimpawu ezithile zentambo, ezinje ngamandla kunye nobuchule. Ezi zinto ziluhlaza zilinganiswa ngononophelo kwaye zidityaniswe ngomlinganiselo ochanekileyo ukuze kufezekiswe iimpawu ezifunwayo.
Xa izinto eziluhlaza zixutyiwe, ziyanyibilika. Umxube ufudunyezwa kwindawo elawulwa kakhulu, ngesiqhelo kwi-oven yombane. Njengoko ubushushu bunyuka, izinto eziluhlaza ziyanyibilika kwaye zenze i-alloy yentsimbi engagqwaliyo engamanzi. Intsimbi engagqwaliyo enyibilikisiweyo emva koko igalelwa kwiimolds ukwenza iimveliso ezigqityiweyo njengee-billets okanye ii-ingots.
Inyathelo elilandelayo kwinkqubo yokuvelisa kukuqengqeleka okushushu kwemveliso egqityiweyo. I-billet okanye i-ingot iyafudunyezwa ize idlule kuthotho lweerola, nto leyo enciphisa kancinci ubukhulu bayo. Inkqubo yokuqengqeleka okushushu inceda ekucoceni ulwakhiwo lwengqolowa yentsimbi engagqwaliyo kunye nokuphucula iimpawu zayo zoomatshini. Ukunciphisa ubukhulu obufumanekayo ngexesha lokuqengqeleka okushushu kubalulekile ukuze kufunyanwe ububanzi bentambo yentsimbi engagqwaliyo oyifunayo.
Emva kokuqengqeleka okushushu, intsimbi engagqwaliyo idlula kwinkqubo ebizwa ngokuba yi-annealing. I-Annealing kukufudumeza intambo yentsimbi engagqwaliyo kubushushu obuthile kwaye igcinwe ixesha elimiselweyo. Le nkqubo ikhulula uxinzelelo lwangaphakathi, ithambise izinto kwaye yenze ukuba zithambile ngakumbi. I-Annealing ikwaphucula isakhiwo sekristale kwaye iphucula ukusebenza kakuhle kwentambo.
Emva kokutsalwa, ucingo lwentsimbi engagqwaliyo lulungele ukutsalwa olubandayo. Ukutsalwa olubandayo kubandakanya ukutsalwa ucingo kuthotho lweedayi ukuze kuncitshiswe kancinci ububanzi balo kwaye kwandiswe ubude balo. Le nkqubo ikwaphucula ukugqitywa komphezulu wocingo, isuse naluphi na uxinzelelo lwangaphakathi olushiyekileyo kwaye iphucule ngakumbi iimpawu zalo zoomatshini. Ucingo lwentsimbi engagqwaliyo lunokutsalwa amaxesha amaninzi ukuze kufezekiswe ububanzi obufunekayo, ukuqinisekisa ukuhambelana kunye nomgangatho.
Inyathelo lokugqibela kwinkqubo yokwenziwa kukulungiswa komphezulu. Ucingo lwentsimbi engatyiwayo ludla ngokufuna unyango lomphezulu olufana nokugalela, ukugalela okanye ukugalela, kuxhomekeke kwindlela olucetywayo ngayo. Ukugalela kubandakanya ukususa isikali okanye ukungcola kumphezulu wocingo, ngelixa ukugalela kudala umaleko omncinci we-oxide ophucula ukumelana nokugqwala. Iinkqubo zokugalela ezifana nokugalela nge-electroplating okanye ukugalela nge-galvanizing nazo zingasetyenziselwa ukubonelela ngokhuseleko olongezelelweyo okanye ukuphucula inkangeleko yocingo.
