I-coefficient yokunwetshwa kwepayipi lensimbi elinembile

I-coefficient yokunwetshwa kweukunemba steel ipayipi

Hlola indlela engasetshenziswa emanzini anensipho esithandweni somlilo ukuze kwesule umfantu ngamunye ohlangene, ukuze ubone ukuthi igesi iyasetshenziswa yini;izindawo lapho igesi cishe ingena khona eshubhuni yomlilo oshisayo futhi ibeke ishubhu endaweni, ama-seal ale ndawo asengozini enkulu yokuguga, Hlola njalo njalo.Kwethulwa ngaphambi kokwakhiwa komqulu wohlelo lwenqubo yokunemba kwensimbi;ukuhlaziywa kwezinga lokushisa elijwayelekile, isikhathi sokubamba kanye nomthelela wokupholisa we-microstructure ye-tube yempahla eluhlaza kanye nezakhiwo zemishini;Ukunquma inqubo evamile yokujwayela ukunemba kwamashubhu ensimbi: izinga lokushisa lokushisa (890 ± 10) ℃, ukupholisa komoya ngemva kokubamba i-6min ehlanganisiwe.Inqubo evamile yokujwayela ingaqedwa ngokuphelele insimbi enembayo i-Widmanstaten ukuze ifane namandla esivuno namandla aqinile anesilinganiso sesivuno esinengqondo σS / bσ≤0.78, ukwelulwa okungu-5δ≥30%, kanye nokwakheka okubandayo okuthuthuke kakhulu kugwema ukuqhekeka okwakhiwe ngokubanda.I-coefficient yokwandisa ingavezwa ngevolumu noma ubude buvame ukuvezwa ngokobude.

Ukuminyana kungubuningi bezinto ezibonakalayo ngeyunithi ngayinye yevolumu yento, iyunithi ingu-kg / m3 noma 1b / in3.Ukucindezelwa kwensalela okuqinile ikakhulukazi okuvela ekucindezelweni kwensalela okuqinile okukhiqizwa ocingweni ngesikhathi senqubo yokushisela.Njengamanje, esetshenziswa kabanzi ekwelashweni kwe-annealing yobunjiniyela ukuze kuqedwe ukucindezeleka okusalayo ngemva kokupholisa kwe-welding, futhi ukupholisa ngemva kokushisela ukucindezeleka kwensalela kuyinqubo ebalulekile, le ndlela iwukuchitha amandla futhi kulula ukuba nokucindezeleka okukhulu kwensalela yokushisela.Ukwelashwa kokushisa kwe-post weld kuwubuchwepheshe obusha bokuqeda ingcindezi esele.Ngaphambi Welding ukunemba steel ipayipi is preheated kuya lokushisa ukwelashwa ukushisa kanye Welding inqubo Weldment ukuqhubeka bafudumale ukuze silondoloze lokhu lokushisa, ukusetshenziswa Welding kuqediwe ukotini ukwahlukanisa ukwahlukanisa bavunyelwe kuphole kancane.Ukucisha ipayipi lensimbi ukwandisa amandla nobulukhuni, kodwa ukunciphisa plasticity yabo.I-ejenti yokucisha evame ukusetshenziswa emanzini, uwoyela, usawoti kanye nesisombululo se-alkali nokunye okunjalo.Izoba nensimbi enembayo eqinile eqinile enembayo eqinile ishisiswe kabusha kuzinga lokushisa elithile, bese kuba nendlela ethile yokupholisa eyaziwa ngokuthi i-temering.Inhloso yalo ukuqeda ukucindezeleka kwangaphakathi okukhiqizwa ukucisha ukunciphisa ubulukhuni nokuqina, ukuze kutholwe izakhiwo ezifunwayo zemishini.Amaphuzu okwehlisa izinga lokushisa eliphezulu, ukufudumala kanye nezinga lokushisa eliphansi elizomisa izigaba ezintathu.Multi-quenching and tempering, normalizing esetshenziswa ngokuhlanganyela.Ngemva kokucisha kanye nokushisa indlela yokucisha ibizwa ngokuthi i-quenching.
