Ubona i-Stellite 6 iza kwiphepha elithile, kwaye ingcinga engoko nangoko inzima kwiivalvu kunye nezihlalo. Akulunganga oko, kodwa kufana nokubiza imela yoMkhosi waseSwitzerland nje ngokuba yincakuba. Kwiminyaka yam ejikeleze iziseko kunye neevenkile zoomatshini, oko kwenziwa lula kuye kwakhokelela kwiimpazamo ezimbalwa kunye namaxesha okukrwela intloko emva kokufakwa. Inyani yile, Stellite 6 yingxubevange yecobalt-chromium-tungsten ukuziphatha kwayo kuqhagamshelwe ngokunzulu kwindlela ecutshungulwa ngayo—iphoswe, idityaniswe, idityaniswe ngoomatshini—kwaye idityaniswa nantoni na. Ayilothuli lomlingo olufefayo kwindawo ethile ukuze ungoyiswa ngoko nangoko.
I-Casting Conundrum: Fluidity vs. Integrity
Iyaphosa Stellite 6 kulapho umaleko wokuqala we-nuance uvela khona. Udumo lwayo lokugalelwa okuhle lufunyanwa, ubukhulu becala ngenxa yolulwelo olundilisekileyo xa lunyibilikisiwe. Siqhube imisebenzi emininzi yokubumba iqokobhe kunye notyalo-mali ngalo kwiziko lethu. Kodwa okulungileyo akuthethi ukuxolela. Iimpawu zokwandiswa kwe-thermal ... ngokukodwa. Ukuba awulumkanga uyilo lwenkqubo yakho yokungena kunye nolawulo lokupholisa, umema iinyembezi ezishushu, ngakumbi kwiijiyometri ezintsonkothileyo ezinamacandelwana amancinci. Ayilotyala lengxubevange; yifiziksi nje efuna intlonipho.
Ndikhumbula ibhetshi yezitshizi zempompo esazenzayo kwiminyaka eyadlulayo. Ushicilelo lubiza Stellite 6 phosa iintsimbi kwindawo yentsimbi engenasici. Ukuqhuba kokuqala kube nesantya sokukhatywa kufutshane ne-30% ngenxa yokuqhekeka kancinci kwindawo yokuhlangana. Umba wawungeyiyo i-alloy chemistry kodwa ukwahluka kokuncipha ngexesha lokuqina. Ukulungiswa kwakuhlengahlengiswa kwenkqubo yokutya ye-mold kunye ne-tweak kwi-preheat ye-heat ye-shell shell shell. Yongeza iindleko kunye nexesha, kodwa yayikuphela kwendlela yokufumana imfezeko yolwakhiwo. Yiloo msebenzi ofihliweyo kunye nala ma-alloys akhethekileyo.
Kulapho amava e-Foundry exela ngokwenene. Ivenkile ekhe yagalelwa kuphela intsimbi engwevu okanye intsimbi yekhabhoni inokufumana imilo echanekileyo, kodwa isandi sangaphakathi sinokuba sesichengeni. Kwi-QSY, kunye namashumi amathathu eminyaka kwiqokobhe kunye nokuphosa utyalo-mali, uphuhlisa ukuziva kwezi zinto-umxube wedatha ukusuka kwimiba edlulileyo kunye nohlengahlengiso oluphantse lwenzeke kwiiparameters zenkqubo kwipateni entsha nganye. Ayinakuze igalele nje intsimbi A kwimold B.
Machining: Inyaniso Abrasive
Ukuba ukuyiphosa kufuna i-finesse, ukuwenza kufuna umonde kunye nezixhobo ezifanelekileyo. Ukufowuna Stellite 6 kunzima ukumatshini kukujongelwa phantsi. Akunzima ngendlela efanayo nentsimbi yesixhobo esiqinileyo; inzima kwaye iyasebenza-inzima ngathi uyaphambana. Thatha isisikeko esikhanyayo kunye nokufakwa okubuthuntu kancinci, kwaye wenze umphezulu olukhuni ngakumbi kunesisiki sakho, uqinisekisa ukusilela kwesixhobo esikhawulezayo kwipasi elilandelayo.
Sifunde oku ngendlela enzima kumsebenzi wokwenza oomatshini we-CNC kumacandelo athile okulungisa ivalvu. I-specs ibize unyamezelo oluqinileyo kubuso obuhlalayo. Indlela yethu yokuqala isebenzisa amabakala aqhelekileyo e-carbide. Yayiyintlekele—ukunxitywa kwezixhobo zokusebenza ngokugqithiseleyo, umphezulu ongemhle, nokukhukuliseka. Isicombululo yayingelonya. Sitshintshele kwibakala elizinikeleyo le-carbide kunye nokulungiswa komphetho obukhali kunye nokuseta izixhobo ezingqongqo ngakumbi. Kwanangoko, isantya kunye nokutya kwakunganyangeki, kwaye samkela ukuba ubomi besixhobo buya kuba bufutshane. Isitshixo kukulawula ubushushu kunye nokugcina ukuguquguquka, ubundlobongela ngokwaneleyo ukusikwa ukuze ungene phantsi komgangatho womsebenzi onzima.
Le yinyani ebonakalayo engenzi ukuba ibe kwiphepha ledatha. Ubulukhuni begumbi-lobushushu obunomtsalane kunye nokumelana nokunxiba kwe Stellite 6 ukuguqulela ngokuthe ngqo kwiindleko eziphezulu zomatshini. Nayiphi na ivenkile ecaphula umsebenzi kufuneka ithathele ingqalelo ukusetyenziswa kwezixhobo kunye namaxesha okucotha komjikelo. Lurhwebo: ukusebenza okumangalisayo kwenkonzo ngokuchasene nokwenziwa kwexabiso eliphezulu.
Umdaniso weWelding: Ukufakwa kobushushu yiyo yonke into
Mhlawumbi esona sicelo sixhaphakileyo sinjengokwaleka kweweld. Kwaye nanku owona mngxunya mkhulu: ukuwuphatha njengenye intsimbi yokuzalisa. I-Stellite 6 isesichengeni sokuqhekeka ukuba i-welded ngokungalunganga yintsomi. Inethiwekhi ye-carbide eyinika iimpawu zayo zokunxiba ingaba yimfanelo ukuba ulahla ubushushu obuninzi kwisiseko sesinyithi.
Siyibonile kwimisebenzi yokulungisa izikrufu ze-extruder. Ivenkile iya kuzama ukwakha inqwelomoya egugileyo nge-Stellite 6 isebenzisa i-high-amp, ubuchule bokupasa enye. Isiphumo sikholisa ukuba kukuqhekeka okusasazeka ukusuka kwindawo echatshazelwe bubushushu ukuya kumanqwanqwa ngokwawo kwiiveki zenkonzo. Indlela echanekileyo ibuhlungu: igalelo lobushushu obuphantsi, rhoqo kusetyenziswa iinkqubo ezifana nePlasma Transferred Arc (PTA) yolawulo olungcono, iileya ezininzi ezibhityileyo, kunye nolawulo olungqongqo lobushushu obuphakathi. Ngamanye amaxesha, ude ufune umaleko wokubhotela we-ductile nickel alloy ngaphambi kokufaka iStellite.
Ngumdaniso phakathi kokuxutywa kunye nokusabalalisa. Ufuna i-fusion eyaneleyo yokudibanisa, kodwa kungekhona kakhulu ukuba izinto zesiseko zetsimbi zinciphisa ukugubungela kwaye zithobe iipropati zayo. Ukufumana oku kulungileyo ngokungaguqukiyo kuko okwahlula umsebenzi ofanelekileyo kwibhombu yexesha lokuphawula. Ayibobuchule obucholachola ngobusuku.
Ukumataniswa kwezinto eziphathekayo kunye noMxholo wokwenyani weHlabathi
IStellite 6 ayifane isebenze yodwa. Ukusebenza kwayo kuhambelana nomxholo, kuchazwa yinto echasene nayo. Ukuqina kwayo okugqwesileyo kunye nokumelana nokuncamathelisa ukunxiba kuyenza ibe lukhetho lwakudala lokutywina ubuso kwiivalvu-cinga isihlalo seStellite 6 ngokuchasene neplagi yeStellite 6. Kodwa kwiindawo ezinodaka oluludaka, njengokuhlamba amalahle okanye iimpompo zemigodi, ukusebenza kwayo kunokumangalisa ngokumangalisayo.
Ndikhumbula ityala elibandakanya iipleyiti zokunxiba impompo eludaka. Umthengi ekuqaleni uchaze ngokupheleleyo Stellite 6 Ukwaleka okusekwe kwireyithingi yokunxiba jikelele. Kwinkonzo, isebenze kakuhle, kodwa hayi ngendlela emangalisayo, kwaye ixabiso laliphezulu. Imowudi yokungaphumeleli yayiyi-abrasion ye-low-stress abrasion evela kumasuntswana amahle, anzima. Kamva sacebisa kwaye savavanya indlela edibeneyo: i-matrix ye-ceramic enzima ngakumbi, i-abrasion-resistant ye-ceramic composite yeendawo zokungena ngokuthe ngqo, kunye ne-Stellite 6 esetyenziswe ngobuchule kwiindawo ezithandwa kakhulu kukhukuliseko lwe-cavitation kunye nokuhlwa. Ubomi benkonzo buphuculwe kakhulu. Isifundo yayikukuba ukunxiba lusapho lweendlela zokusilela, kwaye akukho nto inye, nokuba uStellite, uyinkosi yazo zonke.
Oku kufikelela entliziyweni yobunjineli obusebenzayo. Awukhethi nje imathiriyeli etafileni. Ujonge indlela ethile yokunxiba, ubushushu bokusebenza, ubukho bomhlwa, uxinzelelo lwenkqubo, kunye neendleko zexesha lokuphumla. Ngamanye amaxesha, iStellite 6 lolona khetho lubalaseleyo. Ngamanye amaxesha, i-overkill, okanye ubuthathaka bayo (njengokumelana nempembelelo) iyenza ingafaneleki. Umthengisi oyiqondayo le nto, njenge-QSY, esebenza ngapha kwentsimbi etyhidiweyo, iintsimbi, kunye nezi ngxubevange zikhethekileyo, zinokuba luncedo ekujongeni olu khetho, hayi ukwenza ushicilelo kuphela.
Ngaphaya kweHype: Isixhobo esikwiBhokisi
Ke, yeyiphi into oyithathayo emva kokubona le mathiriyeli kwiindlela ezahlukeneyo-njengokuphoswa kwezixhobo kumgca wethu wotyalo-mali, i-trim eyenziwe ngoomatshini, i-welded overlays kwi-shafts ezinkulu? IStellite 6 sisixhobo sobunjineli esixabiseke kakhulu, kodwa ayisosisombululo sehlabathi. Ixabiso layo livulwa kuphela ngolawulo lwenkqubo oluchanekileyo kunye nokuqonda okunzulu kwee-idiosyncrasies zayo.
Ishishini ngamanye amaxesha liwela kumgibe wokulichaza ngegama lodwa, njengohlobo lwekhubalo lokuqina. Leyo yindlela emfutshane enobungozi. Ingcaciso yokwenyani kufuneka ibandakanye indawo yokusebenza efunekayo kunye nendlela yokwenza izinto. I-alloy ye-Stellite 6 eyenziwe ngokugqibeleleyo inokwenziwa ibephakathi ngoqheliselo olulambathayo lokuphosa, oomatshini abanobundlongo-ndlongo obangela uxinzelelo lwangaphantsi komhlaba, okanye i-welding sloppy eyenza iisayithi zokuqaliswa kokuqhekeka.
Ekugqibeleni, izinto ezifana Stellite 6 khumbuza ukuba ukuveliswa kusetyenziswa isayensi, kungekhona incwadi yokupheka. Amaphepha edatha avela kubavelisi be-alloy akunika amandla. Ngamava aqokelelweyo, ngamanye amaxesha aphumelele nzima kwi-Foundry kunye nevenkile yomatshini-uhlobo olwakhiwe ngaphezu kweminyaka engama-30 kwindawo efana neQingdao Qiangsenyuan Technology-nto leyo iguqulela loo nto inokwenzeka ibe yinto ethembekileyo, icandelo eliphezulu lokusebenza lihleli kwimpompo okanye ivalve kwindawo ethile, yenza umsebenzi wayo ngokuzola iminyaka. Olo guqulelo lolona buchule bokwenene.
