Urumva 'Stellite 21' uhita utekereza 'super alloy,' sibyo? Biragoye kumashini, yambara iteka, kujya-mubihe bikabije. Iyo ni verisiyo y'agatabo. Ukuri kumaduka, cyane cyane iyo uhuye nibice byumurage cyangwa gakondo imwe, ni messier. Ntabwo ari ibijyanye no gukomera gusa cyangwa ibihimbano; bijyanye nuburyo ibintu bitwara mugihe ugerageza kubigira mumaso ya kashe ikora cyangwa trim ya valve idahitana urupfu mumezi atandatu. Abatanga ibicuruzwa benshi bakugurisha gusa ububiko bwemewe kandi ukarabe intoki. Agaciro nyako, uko mbibona, kava mu myambarire yunva urugendo ruva mubikoresho fatizo kugeza igice cyarangiye, gukina no gutunganya saga yose. Aho niho imyambarire ifite ibishingwe byimbitse hamwe na CNC imizi, nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kora icyicaro cyabo. Bamaze imyaka irenga mirongo itatu mumikino yo gukina no gutunganya, bivuze ko bashobora kuba barabonye muburyo bwose cobalt-chrome ivanze ishobora kugutangaza.
Urupapuro rwa 21 rwerekana urupapuro rwerekana imashini
Ibigize izina birasobanutse neza: cobalt-chromium-molybdenum ivanze hamwe nikel nziza. Kurwanya ruswa nziza, kwihanganira galling nziza, bikomeza imbaraga kumuvuduko mwinshi. Urupapuro rwamakuru rutuma rwumvikana nkamasasu ya feza yo kwambara cyane, ubushyuhe bwo hejuru. Ariko ubwambere ushizemo igikoresho, inkuru irahinduka. Ntabwo ari nko gutunganya ibyuma. Irakora-ikaze. Niba umuvuduko wawe, ibiryo, n'inzira y'ibikoresho bitahamagawe neza neza, ntushobora kubigabanya - urimo gusiga gusa ibintu bihenze cyane, bikomeye cyane bizahita bikomeza kurya karbide yawe. Ukeneye gushiraho gukomeye, geometrike nziza, hamwe na coolant nyinshi igamije neza guca. Ninzira wiga ukoresheje ibisakuzo, mubyukuri.
Aha niho inzira ihuriweho na sosiyete nka QSY ifite akamaro. Ntibagura gusa ububiko; batanga casting binyuze Igikonoshwa na gushora imari. Guhera kuri casting yegereye net net ninyungu nini hamwe na Stellite 21. Urimo gukuramo ibikoresho bike, bigabanya igihe cyo gukora, kwambara ibikoresho, hamwe no guhangayika kuruhande. Ariko kuyitera bizana abadayimoni bayo - kugenzura ububobere buke, kwemeza ubutinganyi. Imyaka 30 yabo mugukora amavuta adasanzwe ntabwo ari umurongo wo kwamamaza gusa; ni ububiko bwubumenyi bwuburyo bwo kubona amajwi yibi bikoresho byimiterere mbere yuko CNC izunguruka.
Ndibuka umushinga wo gutunganya kashe ya pompe. Icyifuzo cyahamagaye Stellite 21 kumaso yombi. Umukiriya yabanje gukura impeta zabanje gutunganyirizwa mumaduka asanzwe. Byarananiranye imburagihe kubera micro-fisse ishobora kuba yarakomotse kumikorere itanga ubushyuhe bwinshi bwaho. Twahinduye umucuruzi dukoresheje uburyo bwo guhuza imashini na mashini-ubwoko QSY itanga urugero. Itandukaniro ryari muri microstructure. Guhera kubushyuhe bukwiye bwakorewe mu nzu, uburinganire bwanyuma bwa mashini bwarushijeho kuba bwiza. Igice cyarakomeje. Ntabwo yari amarozi; byari kugenzura urunigi rwose.
Aho Irabagirana (Kandi Aho itagaragara)
Stellite 21 ntabwo ari kubintu byose. Ahantu heza harahantu ufite ibyuma-byuma byanyerera munsi yumutwaro, wenda hamwe nubushyuhe hamwe na ruswa yataye. Tekereza amaboko ya pompe, impeta ya kashe, intebe za valve, kwambara amasahani mubice bishyushye. Kurwanya kwambara kwifata (galling) nicyo kintu cyica. Urashobora kuyirwanya ubwayo cyangwa kurwanya 316 idafite ingese mubihe byinshi utisudira hamwe.
Ariko ikosa risanzwe ni ukujugunya kuri buri kibazo cyo gukuramo. Kubikuramo neza bivuye mubice bikomeye - nkumucanga wumucanga - ibyuma bikomye cyangwa ceramic bishobora kuba amahitamo meza, yubukungu. Stellite 21 irakomeye, ariko irashobora gushakishwa. Imbaraga zayo ni mukurwanya ubwoko bwimyenda itangirana na microwelding kandi igatera imbere.
Indi mbogamizi ni ibidukikije. Nibyiza muri okiside nyinshi no kugabanya aside, ariko witondere hydrochloric na sulfurike mubitekerezo hamwe nubushyuhe. Ugomba kwambukiranya imbonerahamwe ya ruswa. Nabonye byasobanuwe kubisabwa mumazi yo mu nyanja aho chloride yateje kwangirika kuri chromium yabuze. Kunanirwa ntibyari kwambara; byari kwangirika biturutse ku bidukikije byirengagijwe. Umufatanyabikorwa mwiza wa tekiniki agomba gusuzuma ibisobanuro birambuye, ntabwo afata gahunda gusa.
Imbyino Yimashini: Kugaburira, Kwihuta, nubuzima bwigikoresho
Reka dushyire mu bikorwa. Ku musarani wa CNC, uhindura Stellite 21 casting cyangwa bar, urimo ugenda. Biratinda cyane, kandi ukora-gukomera hejuru, bigatuma inzira ikurikira idashoboka. Byihuse cyane, kandi uratangaza igikoresho, biganisha ku gutsindwa gukabije. Kubikomeye, Nagize amahirwe meza hamwe na karbide isize, umuvuduko wo hejuru ugereranije, hamwe nigipimo gihoraho, kigenzurwa. Intego ni ukugera munsi yakazi gakomeye. Guhagarika guhagarikwa ni umwanzi; bakuramo ibikoresho.
Kurangiza nubundi buhanzi. Ukeneye inkombe ityaye, ibiryo byiza kugirango ubone ubuso bwiza, kandi ugomba rwose kwirinda gutura. Aho niho haza ubuhanga bwa CNC bwo gutunganya inzobere. Gutegura gahunda yuburyo bwiza bwibikoresho bikomeza guhuza ibikoresho ni ngombwa. Ntabwo ari ukugira imashini gusa, niyihe QSY urutonde mubushobozi bwabo, ariko kubyerekeye kugira abategura programu nabakoresha bumva imiterere yibikoresho.
Gucukura no gukanda? Birashoboka, ariko ubitegure. Gucukura peck, gufata ibikoresho bikomeye, hamwe na geometrike yihariye ya cobalt alloys ntabwo biganirwaho. Nakwemeza niba ushobora gutegura igice kugirango wirinde diameter-nto, umwobo wimbitse cyangwa insinga nziza muri Stellite 21, kora. Rimwe na rimwe, nibyiza gushushanya ibyuma bifata ibyuma cyangwa ugashyiramo imirimo yihuta kandi ukagira Stellite nkigipfundikizo cyangwa ipadiri. Bikaba biganisha ku ngingo ikurikira ...
Kwinjira no Gutekereza nyuma
Welding Stellite 21, akenshi kubijyanye no gukomera, birasanzwe. Ariko gusudira igice cyuzuye? Nibikorwa byubuhanga buhanitse. Mbere yo gushyushya ubushyuhe na nyuma yo gusudira ni ngombwa kugirango wirinde guturika bitewe na coefficient yayo yo kwaguka kwinshi nubushake bwo gukora ibice byoroshye. Niba ufite igice cyatunganijwe kuva muri casting, urwego rwo gutunganya ubushyuhe bwumushinga nibyingenzi. Irakeneye kugabanya ibibazo bya casting no gutanga ibyifuzwa bya karbide muri matrix.
Gusya ni intambwe yanyuma yo kugera kubwihanganirane bukomeye kandi indorerwamo ikarangirira kumaso. Koresha uruziga rwiburyo (mubisanzwe byoroheje, bifunguye-byubaka aluminium oxyde cyangwa silikoni ya karbide), ibicurane byinshi, hamwe nu mucyo. Ibikoresho bikunda gusya, bishobora gutera impagarara zikomeye hamwe niminota mike - aho gutangirira kunanirwa muri serivisi.
Iyi mitekerereze yuzuye yuburyo bwo gukora - uhereye kumahitamo avanze kurwego rwo gukina (cobalt kuba umwihariko wibanze kubishingwe byinshi) unyuze kumurongo wa nyuma - nicyo gitandukanya ibice bihura nicapiro nibice bikomeza kumurima. Ni itandukaniro riri hagati yikintu nigisubizo cyizewe.
Urubanza mu ngingo: Agaciro Trim Saga
Urugero rufatika rwo kwibuka rwarimo igenzura rya valve kuri serivise yumuvuduko ukabije wa serivise. Imyenda (plug n'intebe) yabanje kuba 17-4PH idafite umwanda. Yamaze amezi agera kuri 8 mbere y’isuri ikabije ndetse no guturika bitera kumeneka. Inzira yo kuzamura ifatwa nka Stellite 6 (karubone yo hejuru, irakomeye, irwanya kwambara ariko idakomeye gato) na Stellite 21.
Twajyanye na Stellite 21 kugirango irusheho kurwanya ingaruka no guhangana na galling muriyi porogaramu yihariye, aho byashobokaga cavitation ntoya. Ikibazo cyari geometrike yimbere yimbere yibice bya trim, bitari byiza gutunganyirizwa mumabari akomeye. Igisubizo kwari ukugira ngo bashore imari yatanzwe ninzobere zinzobere zifite ubushobozi bwo gutunganya. Umucuruzi, bisa murwego rwo Qingdao Qiangsenyuan Technology Co., Ltd., byakozwe hafi-net-shusho ya casting ikoresheje iyabo gushora imari gutunganya, gukora ubushyuhe bukenewe, hanyuma arangiza gutunganya neza CNC kumashanyarazi akomeye. Igisubizo cyari igice cyarokotse umukino wo gusiganwa ku magare hamwe na micro-ingaruka za serivisi. Igiciro cyari hejuru, ariko igiciro cyubuzima bwose cyari gito.
Ikiruhuko? Kugaragaza icyogajuru 21 nintambwe yambere gusa. Ishyirwa mu bikorwa - uko ryakozwe - nicyo gitegeka gutsinda. Ukeneye umufatanyabikorwa ugenzura ibyiciro bikomeye: kubyara amajwi, guterana kimwe; gukora neza ubushyuhe bwiza; no gukora disipuline, yubumenyi. Iyo ibi biri munsi yinzu imwe, itumanaho ryitumanaho rirakomeye, kandi kubazwa birasobanutse. Igabanya impinduka mubikoresho bimaze guhinduka.
Noneho, ubutaha iyo ureba kuri Stellite 21 ku gishushanyo, tekereza ibirenze guhamagarwa. Tekereza kubishingwe, iduka ryimashini, hamwe nuburambe bwuburambe bubahuza. Aho niho ibisobanuro nyabyo biri.
