Nekukurumidza kukura kweindasitiri yemafuta eChina, kudiwa kwesimbi yepamusoro-giredhi kuri kukura, uye simbi yepamusoro-giredhi inofanirwa kudzimwa, uye nekudaro kudzidza kwekudzima kwesimbi kwakakosha. China Heavy Machinery Research Institute yakagadzira "dip quenching + yemukati pfapfaidzo + spin" uye "kunze kwemukati jet shower + spin" maitiro maviri, uye tsvakurudzo nekusimudzira zvine chekuita nekudzima mutsetse, uye yakawana mhedzisiro yakanaka. Ose quenching muitiro ane maitiro ayo, kunze shawa mukati jet quenching kugadzirwa mutsetse wakakodzera mafuta tsime pombi, mafuta casing, chibooreso pombi quenching, zvakawanda zvinobatsira kuti yose quenching mutete rusvingo simbi chubhu; kunyudza kudzima kugadzirwa mutsara wakakodzera madziro ukobvu kuenzanisa Kukura kwese kuomesa yakakwirira kuita gobvu-yakavezwa chubhu, uye zvigadzirwa zvayo zvinonyanya kushandiswa mukudzivirira kwenyika, simba renyukireya, oiri negesi uye maindasitiri emotokari.

Kunyudzwa kunodzima kugadzirwa mutsara
Midziyo yekudzima mudzimba iri kushandiswa parizvino, kune mamwe makobvu-akavezwa nechubhu chakaremara, senge (1), gobvu-yakavakirwa pombi inobhenda inodzimwa nyore, kutwasanuka, kutenderera kwakashata, kune kunotevera kuumbwa kunokonzera matambudziko; (2) mukati uye kunze pombi haigoni kudzimwa, zvichiita Markov muviri kugutsikana yakaderera, kusaenzana kuoma; (3) mari yekushandisa yakakwira, kusachengeteka zvakanaka. Mukupindura kuperevedza uku, chipatara yakazvimirira tsvakurudzo uye budiriro, akakwana seti kugadzira nyika yokutanga kushandiswa "kunyudza quenching + Rotate + mukati pfapfaidzo" quenching simbi pombi rusvingo ukobvu kupfuura 20 mm kubva yose kunyudza quenching quenching quenching kugadzirwa mutsara. Nzira yacho ndeiyi: simbi yakaomeswa muchoto chekudziisa mudziyo → geji yekusvika yakakwidzwa panosimudzwa ichitenderera inoreva kudzvanya kunoreva kudzvanya vhiri retsigiro dhiraivha yesimbi pombi → kutenderedza inotenderera ichisimudza silinda kutyaira simbi furemu kunyudzwa nekukurumidza kunyudzwa mumvura → mukati mekupfapfaidza. muromo wakananga mukati mejekiseni repombi yesimbi → magumo ekudzima, mukati mepombi yekupfapfaidza → pamusoro pekusimudza silinda inosimuka matanda emapuranga esimbi → kupuruzira kumisa mudziyo wekudyisa pamudziyo wekudyisa nebhuroka-ne-kutendeuka kumudzi wemvura isina chinhu. bhuraketi yepombi → Mvura isina chinhu zvinoreva kusimudza rumwe rutivi rwepombi dzakasimudzwa kuwedzera kuvhuvhuta mweya wakadzvanyirirwa kudzima mvura → mvura → kutsika pombi inotakura mukati mepombi inotakurwa zvishoma nezvishoma kuenda kumarori ekudyisa → simbi inoomesa. Izvi kunyudza quenching quenching chikwata kekutanga kushandisa "kunyudza quenching + Rotate + yomukati pfapfaidzo" Michina itsva dhayamita hombe, gobvu-masvingo chubhu yose quenching kugadzirisa guru dhayamita gobvu-walled pombi bend quenching, quenching impervious unyanzvi matambudziko; Isu takawana zvinotevera zvakakosha mhedzisiro: (1) Nekuda kwehuwandu hwehuwandu hwepombi yemvura, kutenderera-kumhanya-mhanya, tsigiro yekubatsira akawanda-poinzi, zvekuti yakavandudza kutwasuka kwesimbi, isingasviki 2 mm / m, kusangana nezvinodiwa chigadzirwa. (2) uchishandisa basa rekutenderera mukati menhare yekupfapfaidza nozzle, kuderedza pombi ovality musoro inogonesa pombi saizi. (3) Nekufamba kwekudzima mukati mekudzima nzira inoshanduka, yakawedzera yunifomu michina yesimbi, mushure mekudzima martensite kutendeuka mwero inopfuura 90%, kunyangwe 95%, kuoma uye ukobvu hwaro hwehurefu hwakazara simbi pombi kukanganisa kwe ≤ 3 HRC.

"Pfapfaidza + kunze kweshawa + yemukati spin" nzira yekudzima.
Iyi nzira inenge yakaonda madziro ukobvu kune pombi. Choto chakaomeswa chesimbi chinopisa kusvika pa1000 ℃, roller yekudyisa kusvika panzvimbo yainotarisirwa, mudziyo wekudyisa kusimudza simbi woipuruzira painononoka kutenderera zvinoreva mavhiri ekutsigira anotenderera, kudzvanywa kwakaiswa paspray rack kukurumidza kusimba zvinoreva kudzvanya pombi, iyo rotary drive zvinoreva kukurumidza kutenderera pombi yesimbi inotenderera, pombi yesimbi inowanikwa zvakananga pamusoro pekunze kwechubhu yekudira kune imwe yunifomu yepombi yekupfapfaidza, nepo pfapfaidzo inoreva kuiswa mupombi inogumira pamadziro epombi kusvika kumusoro wekupfapfaidza. Saka nzvimbo dzemukati nekunze dzepombi yesimbi dzave dzakafanana kudzimwa.
