Inkqubo yokufudumala kwentsimbi ngokubanzi ibandakanya iinkqubo ezintathu: ukufudumeza, ukugquma, kunye nokupholisa.Ngamanye amaxesha kukho iinkqubo ezimbini kuphela: ukufudumeza kunye nokupholisa.Ezi nkqubo zidibene kwaye azinakuphazanyiswa.
1.Ukufudumeza
Ukufudumeza enye yeenkqubo ezibalulekileyo zonyango lobushushu.Zininzi iindlela zokufudumeza zonyango lwetsimbi.Eyokuqala yayikukusebenzisa amalahle namalahle njengomthombo wobushushu, emva koko kusetyenziswe izibaso ezilulwelo nezegesi.Ukusetyenziswa kombane kwenza ukufudumeza kube lula ukulawula kwaye akukho ngcoliseko lokusingqongileyo.Le mithombo yobushushu ingasetyenziselwa ukufudumeza ngokuthe ngqo, okanye ukufudumeza ngokungathanga ngqo ngetyuwa etyhidiweyo okanye isinyithi, okanye amasuntswana adadayo.
Xa isinyithi sishushu, i-workpiece ibonakaliswe emoyeni, kwaye i-oxidation kunye ne-decarburization ihlala isenzeka (oko kukuthi, umxholo wekhabhoni phezu kwendawo yentsimbi iyancitshiswa), enefuthe elibi kakhulu kwiipropati zomphezulu womhlaba. iinxalenye emva kokunyanga ubushushu.Ngoko ke, iintsimbi ngokuqhelekileyo kufuneka zifudunyezwe kwindawo elawulwayo okanye kwindawo ekhuselayo, kwityuwa enyibilikisiweyo, nakwivacuum.Ukufudumala okukhuselekileyo kunokwenziwa kwakhona ngokugubungela okanye iindlela zokupakisha.
Ukufudumala kweqondo lokushisa ngenye yeeparameters zenkqubo ebalulekileyo yenkqubo yokunyanga ukushisa.Ukukhetha kunye nokulawula ubushushu bokufudumala ngumba oyintloko wokuqinisekisa umgangatho wonyango lokushisa.Ubushushu bokufudumala buhluka ngokuxhomekeke kwizinto zetsimbi ezicutshungulwayo kunye nenjongo yonyango lokushisa, kodwa ngokuqhelekileyo ukufudumala ukuya ngaphezu kweqondo elithile lokuguqulwa kweempawu ukufumana isakhiwo esiphezulu sokushisa.Ukongeza, inguqu ifuna ixesha elithile.Ngoko ke, xa umphezulu womsebenzi wesinyithi ufikelela kwiqondo lokushisa elifunekayo, kufuneka ligcinwe kule qondo lokushisa ixesha elithile ukwenza ukushisa kwangaphakathi nangaphandle kuhambelana kwaye ukuguqulwa kwe-microstructure kuphelele.Eli xesha libizwa ngokuba lixesha lokubamba.Xa usebenzisa ukufudumeza koxinzelelo lwamandla aphezulu kunye nonyango lobushushu bomhlaba, isantya sokufudumeza sikhawuleza kakhulu kwaye akukho xesha libambekayo, ngelixa ixesha lokubamba lonyango lobushushu bekhemikhali lihlala lide.
2.Ukupholisa
Ukupholisa kwakhona linyathelo eliyimfuneko kwinkqubo yonyango lobushushu.Iindlela zokupholisa ziyahluka ngokuxhomekeke kwinkqubo, ngokukodwa ukulawula izinga lokupholisa.Ngokubanzi, i-annealing inelona zinga lokupholisa elicothayo, i-normalizing inezinga lokupholisa elikhawulezayo, kwaye ukucinywa kunesantya sokupholisa ngokukhawuleza.Nangona kunjalo, kukho iimfuno ezahlukeneyo ngenxa yeentlobo ezahlukeneyo zetsimbi.Ngokomzekelo, intsimbi ekhuniweyo yomoya inokuqiniswa kwizinga lokupholisa elifanayo njengesiqhelo.
