Inqubo yokukhiqiza yocingo lwensimbi engagqwali: kusuka kumpahla eluhlaza kuya kumkhiqizo ophelile

I-Stainless steel wire iyinto eguquguqukayo esetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yokuqina kwayo, ukumelana nokugqwala kanye namandla aqinile okuqinile.Ukuqonda inqubo yokukhiqiza ucingo lwensimbi engagqwali kusukela esigabeni sempahla eluhlaza kuya ekukhiqizweni komkhiqizo ophelile kubalulekile.Lesi sihloko sizonikeza isingeniso esijulile endleleni yokukhiqiza yocingo lwensimbi engagqwali kanye nobuchwepheshe bokucubungula obuhilelekile ekukhiqizeni.

Uhambo lokukhiqiza lwezintambo zensimbi engagqwali luqala ngokukhethwa kwezinto zokusetshenziswa.Ingxenye eyinhloko yocingo lwensimbi engagqwali i-chromium, okwandisa ukumelana nokugqwala komkhiqizo wokugcina.Ngaphezu kwalokho, ezinye izakhi ezifana ne-nickel, i-carbon kanye ne-manganese zengezwa ukuze kuthuthukiswe izici ezithile zocingo, njengamandla kanye nokwakheka.Lezi zinto zokusetshenziswa zikalwa ngokucophelela futhi zihlanganiswe ngezilinganiso ezinembile ukuze kuzuzwe izakhiwo ezifiselekayo.

Uma izinto zokusetshenziswa sezihlanganisiwe, zingena inqubo yokuncibilika.Ingxube iyashiswa endaweni elawulwa kakhulu, ngokuvamile esithandweni somlilo sikagesi.Njengoba izinga lokushisa likhuphuka, impahla eluhlaza iyancibilika futhi yakhe uketshezi lwensimbi engagqwali ingxubevange.Insimbi engagqwali encibilikisiwe ibe isithelwa ezibunjeni ukuze kwakhiwe imikhiqizo ecishe iqedwe njengamabhilidi noma izingothi.

Isinyathelo esilandelayo senqubo yokukhiqiza ukugoqa okushisayo komkhiqizo osuphelile.I-billet noma i-ingot iyashiswa futhi idlule ochungechungeni lwama-roller, kancane kancane inciphisa ubukhulu bayo.Inqubo yokuginqika eshisayo isiza ukucwenga ukwakheka kokusanhlamvu kwensimbi engagqwali futhi kuthuthukiswe izici zayo zemishini.Ukuncishiswa kogqinsi okuzuzwe ngesikhathi sokuginqika okushisayo kubalulekile ukuze kutholwe ububanzi obufunekayo bensimbi engenasici.

Ngemva kokuginqika okushisayo, insimbi engagqwali ihamba ngenqubo ebizwa ngokuthi i-annealing.I-Annealing iwukushisa intambo yensimbi engagqwali ibe izinga lokushisa elithile futhi uyigcine isikhathi esinqunyiwe ngaphambili.Le nqubo ikhulula ukucindezeleka kwangaphakathi, ithambisa impahla futhi iyenze ibe lula.I-Annealing ibuye icwengisise ukwakheka kwekristalu futhi ithuthukise ukusebenziseka nokwakheka kocingo.

Ngemva kokudonsa, ucingo lwensimbi engagqwali lulungele ukudwetshwa okubandayo.Umdwebo obandayo uhilela ukudweba ucingo ngochungechunge lwamafa ukuze unciphise kancane kancane ububanzi bawo futhi ukwandise ubude bawo.Le nqubo iphinde ithuthukise isiphetho socingo, iqede noma yikuphi ukucindezeleka kwangaphakathi okusalayo futhi ithuthukise ngokuqhubekayo izici zayo zemishini.Intambo yensimbi engagqwali ingadonswa izikhathi eziningi ukuze kuzuzwe ububanzi obufunekayo, kuqinisekiswe ukuvumelana kanye nekhwalithi.

Isinyathelo sokugcina enqubweni yokukhiqiza ukwelashwa okungaphezulu.Intambo yensimbi engagqwali ivamise ukudinga ukwelapha okungaphezulu okufana nokucotshwa, i-passivation noma izinqubo zokumboza, kuya ngokusetshenziswa kwayo okuhlosiwe.I-Pickling ihilela ukususa isikali noma ukungcola ebusweni bocingo, kuyilapho i-passivation idala ungqimba oluncane lwe-oxide oluthuthukisa ukumelana nokugqwala.Izinqubo zokumboza ezifana ne-electroplating noma i-galvanizing nazo zingasetshenziswa ukunikeza ukuvikeleka okwengeziwe noma ukuthuthukisa ukubukeka kocingo.
