Izinqubo zokwelashwa kokushisa kwensimbi zingahlukaniswa cishe zibe izigaba ezintathu: ukwelashwa kokushisa okuphelele, ukwelashwa kokushisa okungaphezulu kanye nokwelashwa kokushisa kwamakhemikhali.Ngokuya ngendawo yokushisa, izinga lokushisa lokushisa kanye nendlela yokupholisa, isigaba ngasinye singahlukaniswa ngezinqubo eziningana ezahlukene zokwelashwa kokushisa.Ukusebenzisa izinqubo ezahlukene zokwelashwa kokushisa, insimbi efanayo ingathola izakhiwo ezihlukene futhi ngaleyo ndlela ibe nezakhiwo ezahlukene.Insimbi iyinsimbi esetshenziswa kakhulu embonini, futhi i-microstructure yensimbi nayo iyinkimbinkimbi kakhulu, ngakho-ke kunezinhlobo eziningi zezinqubo zokushisa ukushisa kwensimbi.
Ukwelashwa kokushisisa sekukonke kuyinqubo yensimbi yokwelapha ukushisa okushisisa ucezu lokusebenza lulonke bese lupholisa ngesivinini esifanelekile ukuze kuguqulwe izici zalo zokusebenza.Ukwelashwa okuphelele kokushisa kwensimbi ngokuvamile kuhlanganisa izinqubo ezine eziyisisekelo: ukuthungatha, ukujwayela, ukucisha kanye nokushisa.
1.Ukukhipha
I-Annealing iwukushisa i-workpiece ibe izinga lokushisa elifanele, ukusebenzisa izikhathi zokubamba ezihlukene ngokuya ngempahla nosayizi wengcezu yokusebenza, bese uyipholisa kancane.Inhloso ukwenza isakhiwo sangaphakathi sensimbi sifinyelele noma sisondele esimweni sokulingana, noma ukukhulula ingcindezi yangaphakathi ekhiqizwe kwinqubo yangaphambilini.Thola ukusebenza okuhle kwenqubo nokusebenza kwesevisi, noma lungiselela ukwakheka ukuze kucishwe futhi.
2.Ukujwayela
Ukwenza ngokwejwayelekile noma ukujwayela ukushisa i-workpiece ezingeni lokushisa elifanele bese upholisa emoyeni.Umphumela we-normalization ufana ne-annealing, ngaphandle kokuthi isakhiwo esitholiwe singcono kakhulu.Ivame ukusetshenziselwa ukuthuthukisa ukusebenza kokusika kwezinto, futhi ngezinye izikhathi isetshenziselwa ukuhlangabezana nezidingo ezithile.Akuzona izingxenye eziphakeme njengokwelashwa kokushisa kokugcina.
3.Ukucisha
Ukucisha ukushisa nokugcina ucezu lomsebenzi, bese ulupholisa ngokushesha endaweni yokucisha njengamanzi, uwoyela noma ezinye izixazululo zikasawoti ezingaphili, izixazululo ezinamanzi aphilayo.
4.Ukushisa
Ngemva kokucisha, insimbi iba nzima kodwa ngesikhathi esifanayo iba brittle.Ukuze kuncishiswe ukuqina kwezingxenye zensimbi, izingxenye zensimbi ezicishiwe zigcinwa ekushiseni okufanelekile ngaphezu kokushisa kwegumbi nangaphansi kuka-650 ° C isikhathi eside, bese zipholile.Le nqubo ibizwa ngokuthi ukuthambisa.I-Annealing, normalizing, i-quenching, kanye nokushisa "imililo emine" ekwelapheni ukushisa okuphelele.Phakathi kwazo, ukucisha nokushisa kuhlobene eduze futhi kuvame ukusetshenziswa ndawonye futhi kudingekile.
"Imililo Emine" iguqule izinqubo ezahlukene zokwelashwa kokushisa ngamazinga okushisa ahlukene nezindlela zokupholisa.Ukuze uthole amandla athile nokuqina, inqubo yokuhlanganisa ukucisha kanye nokushisa okuphezulu kokushisa kubizwa ngokuthi ukucisha kanye nokushisa.Ngemva kokuba amanye ama-alloys ecishiwe ukuze enze isixazululo esiqinile esine-supersaturated, agcinwa ekamelweni lokushisa noma izinga lokushisa eliphakeme kancane isikhathi eside ukuze kuthuthukiswe ubulukhuni, amandla noma izakhiwo ze-electromagnetic ze-alloy.Le nqubo yokwelapha ukushisa ibizwa ngokuthi ukwelashwa kokuguga.
Indlela yokuhlanganisa ngokuphumelelayo nangokuseduze i-deformation processing processing kanye nokwelashwa kokushisa ukuze uthole amandla amahle nokuqina kwe-workpiece ibizwa ngokuthi ukwelashwa kokushisa kwe-deformation;ukwelashwa okushisa okwenziwa endaweni yengcindezi engemihle noma i-vacuum ibizwa ngokuthi i-vacuum heat heat, engagcini nje ngokwenza I-workpiece ngeke ifakwe i-oxidized noma i-decarburized, futhi ingaphezulu le-workpiece ephathwayo izogcinwa ibushelelezi futhi ihlanzekile, ithuthukisa ukusebenza komsebenzi.Kungaba futhi ukushisa ngamakhemikhali nge-ejenti engena.
Njengamanje, ngokukhula okwandayo kobuchwepheshe be-laser ne-plasma, lobu buchwepheshe busetshenziselwa ukufaka ungqimba lwezinye izimbotshana ezingagugi, ukumelana nokugqwala noma ukumelana nokushisa ebusweni bezinsimbi ezijwayelekile zokusebenza ukuze kuguqulwe izakhiwo zensimbi. i-workpiece yokuqala.Le nqubo entsha ibizwa ngokuthi ukuguqulwa kwendawo.
