Reba, iyo abantu benshi bumvise icyogajuru gifite, bahita batekereza kurimburwa. Iri ni ikosa rya mbere. Ni cobalt-chromium ivanze, yego, birakomeye cyane kandi birwanya kwambara, kurigata, no kwangirika. Ariko gukubita icyogajuru hejuru yububiko ntabwo ari ugukosora amarozi. Nabonye ibishushanyo binanirana kuko umuntu yabisobanuye kubikorwa bitari byo, gutekereza gukomera byonyine bikemura byose. Ukuri kurushijeho gusobanuka - ni ugusobanukirwa aho ubwo bukomere bukorera, aho bishobora kuba birenze urugero, kandi cyane cyane, uburyo ubigeza kubice byizewe.
Amavuta Yonyine Nayo Nukuri Kumurika
Icyogajuru ntabwo ari formula imwe. Ufite amanota nka 6, 12, 21 ... buriwese ufite tweaks muri tungsten, karubone, molybdenum. Kubyerekeranye, mubisanzwe uri mubice bya Stellite 6 cyangwa babyara bayo. Ingeso nziza yaryo ntabwo ari ubukana gusa (buri hejuru, hafi 40-50 HRC nkabakinnyi, hejuru iyo ikomye), ariko ubushobozi bwayo bwo kugumana ubwo bukonje mubushyuhe bwo hejuru hamwe no kurwanya hafi yo gufata. Ibi bituma ujya mubihe aho gusiga amavuta ari mariginal, rimwe na rimwe, cyangwa bidashoboka - tekereza amaboko ya pompe mumashanyarazi atagaragara, valve trunnions mumashanyarazi yubushyuhe bwo hejuru, cyangwa imyanya imwe nimwe ivanze cyane.
Ndibuka umushinga kubakiriya batunganya imiti. Bafite ikinyamakuru cyuma kitagira umuyonga cyashaje mu byumweru kubera guhuza aside yoroheje na karryover. Gusiga amavuta ntabwo byari kugenda. Twasabye a Gutwara icyogajuru amaboko hejuru yikinyamakuru. Urufunguzo ntabwo rwari uguhitamo ibintu gusa, ahubwo rwerekanaga Stellite 6B kugirango irusheho kurwanya ruswa rusanzwe 6. Itandukaniro rifite akamaro kubutaka.
Kuruhande? Nibyoroshye. Ntushobora gufata icyogajuru cyashizweho kandi utegereje ko gihanganira ihungabana rikomeye cyangwa ingaruka. Bizakata cyangwa bivunike. Nize ko inzira igoye hakiri kare hamwe na rock crusher progaramu. Ibisobanuro byasabye ko Satelite irenga ku nzu ifite inzu, ariko igishushanyo nticyigeze kibara ibyuma bya tramp rimwe na rimwe. Igisubizo: impanuka yibiza nyuma y'amezi make. Twagombaga gusubira mubikomeye, nubwo bidashobora kwihanganira kwambara, ibikoresho fatizo bifite aho bigarukira.
Gukora Crucible: Gukina na Byuzuye
Aha niho reberi ihurira n'umuhanda. Ntushobora guterura ibintu byose binini biturutse kuri Stellite ikomeye - birahenze cyane kandi biragoye gukina amajwi manini, amajwi arahambaye. Uburyo busanzwe, buhenze cyane ni ugukoresha icyogajuru hejuru yubutaka bukomeye, bworoshye cyane nka karubone cyangwa 316 idafite umwanda.
Aha niho ubushobozi bwumufatanyabikorwa buba ingirakamaro. Ibigo bimaze imyaka ibarirwa muri za casting no gutunganya neza, nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), babonye inzinguzingo. Hamwe nimyaka irenga 30 mugushushanya no gushora imari, bumva guhuza metallurgical. Kuri a Gutwara icyogajuru hejuru, uburyo bwo gutwikira - akenshi gusudira ifu cyangwa PTA (Plasma Transferred Arc) - bigomba kugenzurwa kugirango hirindwe ko icyogajuru cyinjira mu cyuma fatizo no kugabanya ubukana bwa zone. Amateka ya QSY mugukorana nudusimba twihariye, harimo na cobalt, abaha ukuguru muri protocole mbere yubushyuhe na nyuma yubushyuhe, butavugwaho rumwe kugirango batsinde.
Nagenzuye byananiranye aho Stellite igaragara gusa. Intandaro? Hafi buri gihe imyiteguro yubuso idakwiye cyangwa ibikoresho bitari byo. Rimwe na rimwe, ukenera nikel-ishingiye kuri buffer hagati yicyuma na Stellite kugirango ucunge itandukaniro ryubushyuhe butandukanye. Nibisobanuro birambuye bitandukanya ibice byakazi numukandida wa scrap bin.
Gukora no Kurangiza: Inzitizi Yanyuma
Nibyiza, ufite igikoresho cya Stellite yawe neza. Noneho ugomba kuyikora kugirango uyisobanure neza. Iyi ni iyindi nyamaswa. Ntushobora gukoresha HSS isanzwe cyangwa ibikoresho bimwe na bimwe bya karbide; ukeneye amanota yihariye ya karbide, akenshi hamwe na geometrike yihariye, cyangwa ujya gusya. Biratinda, birya ibikoresho, kandi bihenze.
Ubuhanga bwo gutunganya CNC nibyingenzi hano. Igipimo cyibiryo, umuvuduko, nuburebure bwo gukata biratandukanye rwose no gukora ibyuma byoroheje. Amaduka akora cyane cyane aluminium cyangwa ibyuma bisanzwe bizarwana kandi bitange ubuso bubi butesha agaciro imikorere. Kurangiza kuri a Gutwara icyogajuru ubuso bugomba kuba bwiza cyane kugirango wirinde gutangiza ibice no kwemeza neza kashe niba bishoboka. Aka ni akandi gace aho amaduka ahuriweho akora ibintu byombi bivangwa no gutunganya neza, nkuko bigaragara muri serivisi ya QSY, birashobora gukomeza guhuzagurika no kubazwa ibyo bikorwa byose.
Twagize ikibazo aho igicucu cyari gitunganye, ariko gusya kwa nyuma byatangije micro-crack kubera ubushyuhe bwinshi. Igice cyatsinze igenzura ryambere ariko cyananiranye muri serivisi imburagihe. Gukosora byari guhinduranya uburyo bwo gusya-kugaburira hamwe no gukonjesha gukonje. Isomo: urunigi rwibikorwa ntirurangirira kubitsa.
Gusaba Imitego hamwe nukuri-kwisi
Kugaragaza icyogajuru ntabwo ari imyitozo yo kugenzura. Ugomba gusuzuma ubuso bwo gushyingiranwa. Gukoresha icyogajuru ubwacyo ni imyitozo mibi-irashobora gukomeza guhungabana nigitutu gikabije. Ihuriro rya kera ni Stellite irwanya ibintu byoroshye, bihujwe nka 316 bidafite ingese cyangwa umuringa wavuwe bidasanzwe. Ibi bituma ibikoresho byoroshye kwambara bike, gushiramo ibintu byose bivanaho no kurinda icyogajuru.
Ruswa ni iyindi ngingo. Mugihe icyogajuru kirwanya itangazamakuru ryangirika, ntabwo ari inert kwisi yose. Mugabanye cyane acide cyangwa ibidukikije hamwe na chloride mubushyuhe bwinshi, ugomba gusuzuma neza ameza yangirika. Rimwe na rimwe, urwego rwohejuru rudafite ingese cyangwa nikel ishingiye kuri nikel nka Hastelloy birashobora kuba amahitamo meza muri rusange, nubwo imyambarire yayo iba mike. Nubucuruzi.
Igiciro buri gihe cyinjira mubiganiro. Inzira yuzuye ya Satelite yuzuye mugice kinini irashobora kugura 5-10x kurenza icyuma gisanzwe gikomeye. Gutsindishirizwa biva mugihe kinini cyo gukora, kugabanya igihe cyateganijwe, n'umutekano muri sisitemu zifunze cyangwa bigoye-kugera. Ntabwo uyikoresha kuko ni tekinoroji nziza; urayikoresha kuko igiciro cyose cyo gutunga imibare ikora.
Urebye Urunigi rwo gutanga
Gushakisha ibikoresho byizewe byogukora ibyogajuru ntabwo ari ugushaka umucuruzi uhendutse. Nukwishakira umufatanyabikorwa ufite ubumenyi bwibyuma no kugenzura inzira. Amateka yimyaka 30 yikigo nka QSY mugukina no gutunganya amavuta yihariye yerekana ko bagendeye kumurongo wo kwiga wo gukorana nibikoresho bigoye nka cobalt na nikel alloys. Ubunararibonye busobanura muburyo buke bwo gukora no gutanga inama nziza mugice cyo gushushanya.
Iyo nsubiramo utanga isoko, ntabwo ndeba gusa agatabo kabo keza. Ndabaza kubijyanye na PTA weld ibipimo byuzuye, uburyo bwabo bwo kugenzura uburinganire (mubisanzwe kwipimisha ultrasonic), hamwe nibikorwa byabo bisanzwe byo kugabanya imihangayiko. Ndashaka kubona ibikoresho byabo byo gufata ibice bigoye mugihe cyo gutunganya. Ibi nibidasobanutse, bifatika bifatika byemeza igice gikora.
Mu kurangiza, a Gutwara icyogajuru igisubizo nigisubizo cyubuhanga cyane kumurongo wihariye wubugome. Ntabwo ari ibicuruzwa. Intsinzi yayo ishingiye kumyumvire yimbitse, ifatika yimyitwarire ya alloy kuva kumushinga cyangwa gusudira kugeza kumurongo wa nyuma wa micron kurwego rwa mashini ya CNC. Kubyumva neza birasa nkubutsinzi bwikoranabuhanga kandi birasa nkigisubizo cyoroshye cyo kubaha siyanse yibintu n'imbibi.
