Inqubo yokwelapha ukushisa kwensimbi ngokuvamile ihlanganisa izinqubo ezintathu: ukufudumeza, ukwahlukanisa, nokupholisa. Ngezinye izikhathi kunezinqubo ezimbili kuphela: ukushisa nokupholisa. Lezi zinqubo zixhumene futhi azikwazi ukuphazanyiswa.
1.Ukushisa
Ukushisa kungenye yezinqubo ezibalulekile zokwelapha ukushisa. Kunezindlela eziningi zokushisa zokwelashwa kokushisa kwensimbi. Owokuqala wawuwukusebenzisa amalahle namalahle njengomthombo wokushisa, bese usebenzisa izinto zokubasa eziwuketshezi neziyigesi. Ukusetshenziswa kukagesi kwenza ukushisisa kube lula ukulawula futhi akukho ukungcoliswa kwemvelo. Le mithombo yokushisa ingasetshenziselwa ukushisa okuqondile, noma ukufudumeza okungaqondile ngosawoti oncibilikisiwe noma insimbi, noma izinhlayiya ezintantayo.
Lapho insimbi ishisa, i-workpiece ivezwa emoyeni, futhi i-oxidation kanye ne-decarburization kuvame ukwenzeka (okungukuthi, okuqukethwe kwekhabhoni ebusweni bengxenye yensimbi kuyancishiswa), okunomthelela omubi kakhulu endaweni engaphezulu yensimbi. izingxenye emva kokwelashwa kokushisa. Ngakho-ke, izinsimbi ngokuvamile kufanele zishiswe endaweni elawulwayo noma endaweni evikelayo, kusawoti oncibilikisiwe, nasendaweni engenalutho. Ukushisa okuvikelayo nakho kungenziwa ngezindlela zokumboza noma zokupakisha.
Ukushisa okushisa kungenye yemingcele yenqubo ebalulekile yenqubo yokwelapha ukushisa. Ukukhetha nokulawula izinga lokushisa lokushisa kuyindaba eyinhloko yokuqinisekisa ikhwalithi yokwelashwa kokushisa. Izinga lokushisa lokushisisa liyahlukahluka kuye ngezinto zensimbi ezicutshungulwayo kanye nenjongo yokwelashwa kokushisa, kodwa ngokuvamile kushisa libe ngaphezu kwezinga lokushisa lokuguqulwa kwesici esithile ukuze kutholwe isakhiwo sezinga lokushisa eliphezulu. Ngaphezu kwalokho, ukuguqulwa kudinga isikhathi esithile. Ngakho-ke, lapho ubuso be-workpiece yensimbi bufinyelela ekushiseni okushisa okudingekayo, kufanele kugcinwe kulokhu kushisa isikhathi esithile ukuze wenze ukushisa kwangaphakathi nangaphandle kuhambisane futhi ukuguqulwa kwe-microstructure kuphelele. Lesi sikhathi sibizwa ngokuthi isikhathi sokubamba. Uma usebenzisa ukushisisa okunamandla amakhulu kanye nokwelashwa kokushisa kwendawo, isivinini sokushisisa siyashesha kakhulu futhi ngokuvamile asikho isikhathi sokubamba, kuyilapho isikhathi sokubamba sokwelapha ukushisa ngamakhemikhali sivame ukuba side.
2.Ukupholisa
Ukupholisa futhi kuyisinyathelo esibalulekile enqubweni yokwelapha ukushisa. Izindlela zokupholisa ziyahlukahluka kuye ngenqubo, ikakhulukazi ukulawula izinga lokupholisa. Ngokuvamile, ukukhishwa kwe-anneal kunezinga lokupholisa elihamba kancane, ukujwayelekile kunezinga lokupholisa elisheshayo, futhi ukucisha kunezinga lokupholisa elisheshayo. Nokho, kunezidingo ezahlukene ngenxa yezinhlobo ezahlukene zensimbi. Isibonelo, insimbi eqinile emoyeni ingaqiniswa ngesilinganiso sokupholisa esifanayo njengokujwayelekile.
