Inqubo Yenhloso Yokunaniselwa Okukhanyayo Okungagqwali

Qeda ukuqina komsebenzi ukuthola isakhiwo se-metallographic esigculisayo　

Isithando somlilo esikhanyayo sisetshenziselwa ukwelashwa ukushisa kwensimbi engagqwali eqediwe ngaphansi komoya wokuvikela. Lapho izidingo zokusebenza zingafani, izidingo zesakhiwo se-metallographic ngemuva kokuncishwa okukhanyayo kwehlukile, futhi nenqubo yokwelashwa kokushisa okukhanyayo nayo yehlukile.　

Inqubo ejwayelekile yokwelashwa kokushisa kwezinsimbi ezingama-300 zensimbi engenasici ukwelashwa kwesisombululo. Ngesikhathi senqubo yokushisa, i-carbide ichitheka ibe yi-austenite, ifudunyezwe ibe ngu-1050 kuya ku-1150 ℃, igcinwe kahle isikhathi esifushane, ukuze wonke ama-carbide ancibilike ku-austenite, bese epholile ngokushesha abe ngaphansi kwama-350 ℃ ukuthola Isixazululo esiqinile esilinganayo esilinganayo Isakhiwo se-unidirectional austenite. Ukhiye wale nqubo yokwelashwa kokushisa ukupholisa okusheshayo, okudinga isilinganiso sokupholisa esingu-55 ° C / s, futhi kudlule ngokushesha endaweni yokushisa yokushisa kabusha (550-850 ° C) ngemuva kwesisombululo esiqinile se-carbide. Isikhathi sokubamba kufanele sibe sifushane ngangokunokwenzeka, ngaphandle kwalokho okusanhlamvu kwe-crystal kuzoba kukhulu, okuzothinta ukuphela kwaphezulu.　

Insimbi engagqwali yochungechunge i-ferritic engamakhulu amane inezinga lokushisa eliphansi uma kuqhathaniswa (cishe u-400 ° C), futhi ukupholisa ngokunensa kuvame ukusetshenziselwa ukuthola isakhiwo esithambile esinciphisiwe. I-Martensitic insimbi engenasici yengeziwe, futhi ingalashwa ngokuqeda nokushisa ngezigaba.　

Ukusuka kokungenhla, kungabonakala ukuthi uhlelo lokwelashwa kokushisa lwamachungechunge angama-300 nochungechunge lwensimbi olungenasici olungama-400 luhluke kakhulu. Ukuthola isakhiwo se-metallographic esifanelekayo, isigaba sokupholisa sesithando somlilo esikhanyayo siyadingeka ukuthi sibe negumbi eliningi lokulungisa. Ngakho-ke, isithando somlilo esikhanyayo sesimanjemanje esivame ukwamukela ukupholisa okuqinile kwe-convection esigabeni saso sokupholisa, ezinezigaba ezintathu zokupholisa, ezingakwazi ukulungisa ivolumu yomoya. Ihlukaniswe izigaba ezintathu ngokuya ngobubanzi bomucu, futhi isivinini sokupholisa esiqondisweni sobubanzi bomugqa silungiswa ukuphambukiswa kwevolumu yomoya ukulawula ukuma kwepuleti.　　

Olunye udaba olusemqoka ekwelapheni ukushisa komugqa wensimbi ongenagwele ogoqwe amakhaza ngukuthi umucu wonke uyadingeka ukuthi ube nesakhiwo esifanayo ngobubanzi nobude. Isithando somlilo esifana nohlobo lwe-muffle sisebenzisa ishubhu enkulu yomswakama, ehlela ngokulinganayo ukuphuma komoya okushisayo okuvela ngaphandle kwethubhu le-muffle ukuzungeza, ukuze umucu ushiswe ngokulinganayo. Ukuqinisekisa ukwakheka okufanayo komugqa eceleni kwenkomba yobude, i-velocity eqondile yomugqa esithandweni sokushisa kufanele igcinwe njalo. Ngakho-ke, kufakwa ngaphambi nangemva kwesithando sokwelashwa sokushisa okukhanyayo okuqondile mpo. Akufanele nje kuphela ukuthi isivinini sokungenisa nokukhipha insimbi sihlangabezane nezidingo zejubane lokwelashwa kokushisa, futhi singathinteki ngobuningi obungenalutho noma obugcwele bomkhono, kepha futhi nokungezwani okuncane kwesiqeshana kufanele kusungulwe futhi kulungiswe ngokunembile ngokuya ngomumo womugqa ukuhlangabezana nezidingo zendlela yomugqa. Faka isicelo.　

2Thola indawo ekhanyayo ngaphandle kwe-oxidation 　

Ukuncishwa okukhanyayo ukwelashwa kokushisa kwensimbi yensimbi ngaphansi komoya wokuvikela we-H2. Ukuhlangabezana nezidingo zebhodi le-BA, isimo esivikelayo esithandweni somlilo kufanele silawulwe ngokuqinile ukugwema i-oxidation ngangokunokwenzeka. Kwenzeka kanjani ukuba namachibi ngaphansi komkhathi wokuvikela we-H2? 　

Izingxenye eziyinhloko ze-alloy yensimbi engagqwali yi-Fe, Cr, Ni, Mn, Ti, Si, njll. Ebangeni lokushisa elingenayo, i-oxidation kaFe noNi akuyona inkinga enkulu. Noma kunjalo, uhla lwe-oxidation lwe-Cr, Mn, Si, ne-Ti lungaphakathi kwebanga lokushisa lokushisa. Kuyinto i-oxidation yalezi zinto ezihlanganayo ezithinta ukukhanya kwensimbi yensimbi. Ngokuyinhloko, i-oxidation ye-chromium isusa ubuso bensimbi yomugqa, okuzonciphisa ukumelana nokugqwala kwensimbi engagqwali. Lapho okuqukethwe kuka-Cr kuphakathi kuka-17% no-18% futhi okuqukethwe ku-Ti kungu-0.5%, iphuzu lamazolo le-H2 kufanele libe ngaphansi kuka -60 ° C ukugwema uketshezi kuka-Cr no-Ti ebangeni lokushisa elingu-800 ° C kuya ku-1150 ° C.
