Inqubo Yokushisa Ukwelashwa Kwe-Cast Iron

Ngaphezu kokukhethwa okufanele kwezithako ezinhle kakhulu ekukhiqizeni i-cast iron ukuthola isakhiwo esinqunyelwe kusengaphambili, ukwelashwa kokushisa futhi kuyindlela ebalulekile yokuqhubeka nokulungisa nokwenza ngcono isakhiwo se-matrix ukwenza ngcono ukusebenza kwensimbi yensimbi. Ukwelashwa kokushisa kwensimbi yensimbi nokushumeka okushisayo kwensimbi kunokufana nokwehluka. Ukwelashwa ngokushisa kwensimbi yensimbi ngokuvamile akunakuthuthukisa i-morphology nokusatshalaliswa kwe-graphite esakhiweni sokuqala.

Nge-iron cast iron, umphumela wokuhlushwa kwengcindezi obangelwa i-flake graphite yinto ebaluleke kakhulu ekusebenzeni kwensimbi yensimbi. Ngakho-ke, umphumela wokuqinisa ukwelashwa kokushisa ku-grey cast iron ubaluleke kakhulu kunowensimbi nensimbi ye-ductile. Ngakho-ke, inqubo yokwelashwa kokushisa kwe-Youkou cast iron ngokuyinhloko ihlanganisa futhi ijwayelekile. Okwe-ductile iron, ngoba i-graphite iyindilinga, umphumela wokuqhekeka ku-matrix unciphise kakhulu, futhi isakhiwo se-matrix singasetshenziswa ngokuphelele ukwelashwa kokushisa, okungathuthukisa kakhulu izakhiwo eziyindilinga eziyindilinga.

Ngakho-ke, i-ductile iron ifana nensimbi, futhi izinqubo zayo zokwelashwa kokushisa zifaka phakathi ukuthanjiswa, ukujwayela, ukucima kanye nokushisa, ukucisha ukushisa okuningana, ukucisha ukufudumeza kokushisa kanye nokwelashwa kokushisa kwamakhemikhali angaphezulu.

Inqubo yokwelashwa ngokushisa kwensimbi yensimbi

1. Ukuncishiswa kwengcindezi

Ngenxa yokungalingani kodonga okungalingani kokuphonsa, amandla womphumela kanye nengcindezi yesakhiwo kuzokwenziwa ngesikhathi sokushisa, ukupholisa nokushintsha kwesigaba. Ngaphezu kwalokho, izingxenye ezinkulu zithambekele ekucindezelekeni okusalile ngemuva kokulungiswa, futhi zonke lezi zingcindezi zangaphakathi kufanele zisuswe. Ukushisa okujwayelekile kokushisa kokuncishiswa kwengcindezi ngu-500 ～ 550 ℃, isikhathi sokubamba ngu-2 ～ 8h, bese kuthi ukupholisa kwesithando somlilo (impunga yensimbi) noma ukupholisa umoya (i-ductile iron). Ukusebenzisa le nqubo kungasusa i-90-95% yengcindezi yangaphakathi yokusakaza, kepha ukwakheka kwensimbi eyakhiwe akuguquki. Uma izinga lokushisa lidlula u-550 ℃ noma isikhathi sokubamba side kakhulu, sizodala i-graphitization futhi sinciphise amandla nobulukhuni bokusakaza.

2. Susa ukukhipha i-graphitization okushisa okuphezulu komlomo omhlophe wokusakaza

Lapho ukusakaza sekupholile, ungqimba olungaphezulu kanye nesigaba esincanyana kuvame ukuba nemilomo emhlophe. Isakhiwo somlomo omhlophe sinzima futhi siqhekekile, sisebenza kabi ekusebenzeni futhi kulula ukuphuma. Ngakho-ke, indlela yokuncishiswa (noma ukujwayela) kumele isetshenziselwe ukuqeda isakhiwo somlomo omhlophe. Inqubo yokuncishiswa yilezi: ukufudumeza kube ngu-550-950 ° C ngamahora ama-2 kuye kwangama-5, bese isithando somlilo sipholisa sibe ngu-500-550 ° C bese kupholisa umoya. Ngesikhathi sokubamba izinga lokushisa okuphezulu, i-cementite ephezulu ne-eutectic cementite iyawohloka ibe yi-graphite ne-A, kanti i-cementite yesibili ne-eutectoid cementite nayo iyawohloka ngesikhathi senqubo yokupholisa elandelayo, bese inqubo ye-graphitization yenzeka. Ngenxa yokubola kwe-cementite, ubulukhuni buyancipha, ngaleyo ndlela kuthuthukiswe ukusebenza kahle.

3. Ukwenza okujwayelekile kwe-ductile iron

Inhloso yokwenza insimbi ye-ductile ifane nokuthola isakhiwo se-pearlite matrix, nokucwenga okusanhlamvu kwe-crystal nesakhiwo esifanayo ukuze kuthuthukiswe izakhiwo zemishini esetshenziswayo. Kwesinye isikhathi ukujwayela futhi kulungiselela ukucinywa komhlaba kwensimbi ye-ductile. Ukwenza okujwayelekile kuhlukaniswe ngokushisa okuphezulu okujwayelekile kanye nokushisa okuphansi okujwayelekile. Izinga lokushisa elijwayelekile lokushisa ngokuvamile alidluli i-950-980 ℃, futhi izinga lokushisa eliphansi elijwayelekile livamise ukufudumeza ebangeni lokushisa eliguqukayo eliyi-820-860 ℃. Ngemuva kokujwayela, kudingeka abantu abane ukubhekana nayo ukuqeda ukucindezeleka kwangaphakathi okwenziwe ngesikhathi sokujwayela.

4. Ukucima nokushisa kwensimbi ye-ductile

Ukuze kuthuthukiswe izakhiwo zemishini yensimbi ye-ductile, ukusakazwa ngokujwayelekile kufudunyezwa kube ngu-30-50 ° C ngenhla kwe-Afc1 (i-Afc1 imele izinga lokushisa lokugcina le-A ukwakheka ngesikhathi sokushisa), bese icinywa ku-oyili ngemuva kokulondolozwa kokushisa ukuthola isakhiwo se-martensitic. Ukuze unciphise ngokufanele ukucindezelwa okusele ngemuva kokucima, ukufuthelana kufanele kwenziwe ngemuva kokucishwa. Isakhiwo se-tempering esinezinga lokushisa eliphansi sine-martensite enomoya onensalela ye-bainite ne-nodular graphite. Lesi sakhiwo sinokumelana okuhle kokugqoka futhi sisetshenziselwa izingxenye ezidinga ukumelana nokugqoka okuphezulu namandla amakhulu. Ukushisa okushisa kwamazinga okushisa aphakathi nendawo kungu-350-500 ℃. Isakhiwo ngemuva kokushisa siyi-tempered troostite kanye ne-graphite eyindilinga, efanelekile ezingxenyeni ezijiyile ezidinga ukumelana nokugqoka okuhle, ukuqina nokunwebeka. Izinga lokushisa eliphakeme Ithempelesha ye-tempering ingama-500-60D ℃, isakhiwo ngemuva kokufuthwa umoya yi-Soxhlet enziwe nge-spheroidal graphite, enenhlanganisela enhle yobulukhuni namandla, ngakho-ke isetshenziswa kakhulu ekukhiqizeni.

5. Ukucisha okushisa okuningi kwensimbi ye-ductile

I-Ductile iron ingathola amandla aphezulu ngemuva kokuqina, ngenkathi inepulasitiki enhle nobulukhuni. Ukukhethwa kwezinga lokushisa lokucisha ukushisa okushisa okuningi kubheka ukuthi isakhiwo sokuqala sakhiwe ngokuphelele ngo-A, ngaphandle kwensalela F, futhi ngasikhathi sinye, sigwema ukukhula kwe-A crystal grains. Ithempelesha yokushisa imvamisa ingu-30-50 ° C ngenhla kwe-Afc1, kanti izinga lokushisa le-isothermal liyi-0-350 ° C ukuqinisekisa ukuthi isakhiwo esiphansi se-bainite esinezinto eziphelele zokutholwa siyatholakala. I-iron evamile ye-magnesium aluminium ductile yensimbi ngemuva kokucishwa kwe-isothermal σb = 1200 ～ 1400MPa, αk = 3 ～ 3.6J / cm2, HRC = 47 ～ 51. Kepha kufanele kuqashelwe ukuthi inqubo ye-tempering kufanele ingezwe ngemuva kokuthola amandla.

6. Ukuqina kwangaphandle

Ukuze uthuthukise ukuqina kobuso, gqoka ukumelana namandla okukhathala kokunye ukusakaza, ukucima indawo kungasetshenziswa. Kokubili i-iron cast cast kanye ne-ductile iron castings kungabanzima ebusweni. Ngokuvamile, ukushuba okushisayo okuphezulu (okuphakathi) kokuqina kobuso nokuqina kobuso bokuxhumana kusetshenziswa.

7. Ukwelashwa kokushisa ngamakhemikhali

Okokuphonsa okudinga ukumelana nokugqoka komhlaba, ukumelana ne-oxidation, nokumelana nokugqwala, izinqubo zokwelashwa ngamakhemikhali ezifana nensimbi zingasetshenziswa, njengegesi "target =" _ blank "> i-chlorine ethambile yegesi, i-chlorination, i-boronizing, i-sulfurizing nezinye izindlela zokwelapha.
