I-Annealing inqubo yokwelapha ukushisa kwamapayipi ashiselwe ensimbi engagqwali.Inhloso yayo ukuqeda ukucindezeleka okusalayo, ukuzinzisa ubukhulu, nokunciphisa ukuthambekela kokuguquguquka nokuqhekeka.

Kuyini ukuhushulwa kwepayipi lensimbi engagqwali engu-2205?

Ngepayipi elikhiqizwa ukusebenza okubandayo, imvula ye-carbide, ukonakala kwe-lattice, kanye nesakhiwo esingahambisani nokubunjwa kuzobangela ukumelana nokugqwala kwensimbi engagqwali kwehle.Ngalesi sikhathi, ukwelashwa kwe-annealing (noma ukwelashwa kwesixazululo) kuyadingeka.

Kungani ipayipi lensimbi engu-2205 likhishwa?

Yehlisa ubulukhuni bensimbi futhi uthuthukise i-plasticity ukuze kube lula ukusika kanye nokucubungula okubandayo kwe-deformation

Cwenga okusanhlamvu, i-homogenize isakhiwo sensimbi nokwakheka, thuthukisa izakhiwo zensimbi noma ulungiselele ukwelashwa kokushisa okulandelayo

Susa ukucindezeleka kwangaphakathi okusele ensimbi ukuvimbela ukuguquguquka nokuqhekeka.

2205 insimbi engagqwali annealing inqubo

Ekukhiqizeni, inqubo yokudonsa isetshenziswa kabanzi.Ngokwezinjongo ezihlukene zokuhushula odingwa ucezu lokusebenza, kunezicaciso zenqubo yokuhoxisa eyahlukene, evame ukusetshenziswa ukuhushula ingcindezi, ukuhoxisa ngokuphelele kanye ne-spheroidizing annealing.

Ukunciphisa ingcindezi.Izinto ezisetshenziswayo ezijwayelekile zokuvala ingcindezi yamashubhu ensimbi engagqwali isithando somlilo esiqhubekayo esikhanyayo samashubhu ensimbi engagqwali, okuwuhlobo lwesithando somlilo esikhanyayo esiwuhlobo lwe-muffle.Umthombo wegesi ovikelayo wamukela isithando somlilo sokubola i-ammonia futhi ufakwe idivayisi yokuhlanza igesi. I-Hangao Tech (i-SEKO Machinery) yenze uguquko lwesakhiwo sesithando somlilo se-muffle, yasusa indlela yokudlulisa ibhande elinenetha futhi yafaka esikhundleni salo nge-roller yeshubhu eyodwa eqhubekayo edlulisa umugqa.Okokusebenza kunezici zokulawula okuthuthukile, ukonga amandla okumangalisayo, ukunakekelwa okufanele, njll. Indawo yokushisisa yawo wonke ulayini isebenzisa ukulawulwa kwezinga lokushisa okuzenzakalelayo kwe-PID yezindawo eziningi.Amapayipi ensimbi engagqwali aphathwa ngokushisisa ngokunciphisa kwethu ukulondolozwa ukushisa ipayipi yensimbi engagqwali elikhanyayo annealing isithando somlilo ukuguquguquka futhi aqinisekise i-ellipticity yamapayipi.

Imichilo yensimbi engagqwali ihlelwe ngokulinganayo ku-rack yokudla, ithunyelwa esithandweni somlilo ngebhande lokuhambisa, ishiselwe ku-1050-1080 ℃ ngaphansi kokuvikelwa komoya olawulekayo, bese igcinwa isikhathi esifushane, wonke ama-carbides angakwazi. zincibilike esithandweni somlilo.Esakhiweni se-austenite, bese sipholiswa ngokushesha sibe ngaphansi kuka-350 ° C, isisombululo esiqinile esine-supersaturated, okungukuthi, isakhiwo se-unidirectional unidirectional austenite, singatholakala.

Ikhishwe ngokuphelele.Isetshenziselwa ukucwenga isakhiwo esishisayo esishisayo esinezakhiwo ezimbi zemishini ngemuva kokusakazwa, ukubumba kanye nokushisela kwensimbi ye-carbon ephakathi nendawo nephansi.Shisisa i-workpiece ekushiseni kuka-30-50 ° C ngaphezu kwezinga lokushisa lapho yonke i-ferrite ishintsha ibe i-austenite, ibambe isikhathi esithile, bese upholisa kancane ngesithando somlilo.Phakathi nenqubo yokupholisa, i-austenite ishintsha futhi, engenza isakhiwo sensimbi sibe mncane..

I-Spheroidizing Annealing.Isetshenziselwa ukunciphisa ubulukhuni obuphezulu bensimbi yamathuluzi kanye nensimbi yokuthwala ngemuva kokubumba.I-workpiece ishisa ku-20-40 ° C ngaphezu kwezinga lokushisa lapho insimbi iqala ukwakha i-austenite, bese ipholisa kancane kancane ngemva kokugcinwa kokushisa.Phakathi nenqubo yokupholisa, i-lamellar cementite ku-pearlite iba yindilinga, ngaleyo ndlela inciphisa ubulukhuni.
