Izakhiwo ezingokoqobo namakhemikhali ezinsimbi ezisetshenziswayo azinzinzi neze ngenxa yenani eliphezulu lokungcola ohlelweni lokumba. Inqubo yokwelapha ukushisa ingabahlanze ngempumelelo futhi ithuthukise ukuhlanzeka kwabo kwangaphakathi, futhi ubuchwepheshe bokwelapha ukushisa bungaphinda buqinise ukuthuthukiswa kwekhwalithi yabo futhi buthuthukise ukusebenza kwabo kwangempela. Ukwelashwa kokushisa kuyinqubo lapho i-workpiece ishiselwa endaweni ethile, ishiselwe ezingeni elithile lokushisa, igcinwe kulelo zinga lokushisa isikhathi esithile, bese ipholiswa ngamanani ahlukene.
Njengenye yezinqubo ezibaluleke kakhulu ekukhiqizeni izinto zokwakha, ubuchwepheshe bokwelapha ukushisa kwensimbi bunezinzuzo ezinkulu uma kuqhathaniswa nobunye ubuchwepheshe obujwayelekile bokucubungula. “Imililo emine” ekwelapheni ukushisa kwensimbi isho ukuncibilika, ukujwayela, ukucisha (isixazululo) kanye nokushisa (ukuguga). Uma i-workpiece ishisa futhi ifinyelela izinga lokushisa elithile, i-annealed kusetshenziswa izikhathi ezihlukene zokubamba kuye ngosayizi we-workpiece kanye nempahla, bese ipholiswa kancane kancane. Inhloso eyinhloko ye-annealing ukunciphisa ubulukhuni bezinto ezibonakalayo, ukuthuthukisa ipulasitiki yezinto, ukusiza ukucubungula okulandelayo, ukunciphisa ukucindezeleka okusele, nokusabalalisa ngokulinganayo ukubunjwa nokuhlelwa kwezinto.
Imishini yokusebenzisa amathuluzi omshini kanye nemishini yokucubungula izingxenye zenqubo yokucubungula,ukwenziwa kwezingxenyengaphambi nangemva kokucutshungulwa kuzoba yinqubo yokwelapha ukushisa ehambisanayo. Indima yayo uku.
1. Ukususa ukucindezeleka kwangaphakathi kokungenalutho. Ikakhulu isetshenziselwa ukubunjwa, ukubumba, izingxenye ezishiselwe.
2. Ukwenza ngcono izimo zokucubungula, ukuze izinto zibe lula ukucubungula. Njenge-annealing, normalizing, njll.
3. Ukuthuthukisa izakhiwo zemishini eziphelele zezinto zensimbi. Njengokwelashwa kokupholisa.
4. Ukuthuthukisa ubulukhuni bezinto ezibonakalayo. Njengokucisha, ukucisha i-carburizing, njll.
Ngakho-ke, ngaphezu kokukhethwa okunengqondo kwezinto kanye nezinqubo ezihlukahlukene zokwakha, inqubo yokwelapha ukushisa ngokuvamile ibalulekile.
Ukwelashwa kokushisa ngokuvamile akushintshi ukuma kanye nokwakheka kwamakhemikhali sekukonke kwengcezu yokusebenza, kodwa ngokushintsha i-microstructure ngaphakathi kwendawo yokusebenza, noma ukushintsha ukwakheka kwamakhemikhali okungaphezulu kwendawo yokusebenza, ukunikeza noma ukuthuthukisa ukusebenza komsebenzi osetshenziswayo. Ibonakala ngokuthuthuka kwekhwalithi yangaphakathi ye-workpiece, ngokuvamile engabonakali ngeso lenyama.
