I-Graphite rotorUkuphosa i-aluminiyam sisixhobo esiyimfuneko esiyimfuneko kwishishini lokuphosa i-aluminium ingxubevange, umsebenzi wayo kukuhlambulula ukunyibilika kwe-aluminium kunye nokuphucula umgangatho kunye nokuzinza kwe-aluminium alloy casting. Eli nqaku liza kuhlolisisa umgaqo wokusebenza, iingenelo, iimpawu, kunye nezisombululo ezenziwe ngokwezifiso ze-graphite rotors ukwenzela ukuphosa i-aluminium, ukuze kuncede abantu abaninzi baqonde ukubaluleka kunye neendawo zokusetyenziswa kwesi sixhobo esibalulekileyo.
Umgaqo osebenzayo: isitshixo sokucoca i-aluminium enyibilikayo
Umsebenzi oyintloko we-graphite rotor yokuphosa i-aluminium kukujova i-nitrogen okanye i-argon gas kwi-aluminium inyibilika ngokujikeleza, ukwaphula igesi kwinani elikhulu lamaqamza ahlakazekileyo kwaye uwasasaze kwintsimbi etyhidiweyo. Emva koko, i-rotor yegraphite isebenzisa igesi eyahlukileyo yoxinzelelo lwamaqamza ekunyibilikeni kunye nomgaqo wokungeniswa komphezulu ukufunxa igesi yehydrogen kunye ne-oxidation slag ekunyibilikeni. La maqamza ngokuthe ngcembe aphakama ngokujikeleza kwe-rotor yegraphite kwaye athathe iigesi ezinobungozi kunye neeoksidi ezibhengezwayo kumphezulu wokunyibilika, ngaloo ndlela edlala indima ekuhlambululeni inyibilika. Ngenxa yokusabalalisa okuncinci kunye nokufana kwamaqamza kwi-melt, exutywe ngokulinganayo kunye ne-melted kwaye ingenzi ukuhamba komoya okuqhubekayo, igesi ye-hydrogen enobungozi kwi-aluminium inyibilika inokususwa ngempumelelo, iphucula kakhulu umphumo wokucoca.
Izinto eziluncedo kunye neempawu ze-graphite rotor
Iirotha zegraphite zokuphosa i-aluminiyam zineenzuzo ezininzi kunye neempawu kwi-aluminium alloy casting, ezenza zithandeke kakhulu. Okokuqala, i-nozzle ejikelezayo ye-graphite rotor yenziwe nge-graphite ephezulu ecocekileyo kunye nonyango olukhethekileyo, ngoko ubomi bayo benkonzo buhlala buphindwe kathathu kwiimveliso eziqhelekileyo. Oku kuthetha ukuba i-graphite rotors inokusebenza ngokuzinzileyo ixesha elide, ukunciphisa ukutshintshwa rhoqo kunye neendleko zabasebenzi.
Okwesibini, i-graphite rotors inokunciphisa iindleko zokucubungula, ukusetyenziswa kwegesi ye-inert, kunye nomxholo we-aluminium kwi-aluminium enyibilikayo. Ngethuba lokuchithwa kwe-degassing kunye nenkqubo yokuhlanjululwa, ngokusebenzisa isakhiwo se-nozzle esilungiselelwe ngokufanelekileyo, i-rotor ye-graphite inokusasaza iibhubhu kwaye idibanise ngokulinganayo kunye ne-aluminium alloy liquid, ukwandisa indawo yokudibanisa kunye nexesha phakathi kweebhubhu kunye ne-aluminium alloy liquid, ngaloo ndlela iphucula i-degassing kunye nesiphumo sokucoca.
Ukongezelela, isantya se-graphite rotor sinokulawulwa ngokulawulwa kwesantya sokuguqula i-frequency, ukufezekisa ukulungelelaniswa okungapheliyo, kunye nobuninzi be-700 r / min. Oku kubonelela ngokulula kokusebenza kunye nokulawula ngexesha lenkqubo yokuvelisa, okwenza ukuba izinga lokukhupha igesi lifikelele ngaphezu kwe-50%, linciphise ngakumbi ixesha lokunyibilikisa kunye nokunciphisa iindleko zemveliso.
Isisombululo esilungiselelweyo: ukuhlangabezana neemfuno ezahlukeneyo
Kuyilo kunye nokucwangciswa kwe-rotors yegraphite yokuphosa i-aluminium, ngenxa yenkcazo eyahlukeneyo ye-rotors yegraphite esetyenziswa kwimigca eyahlukeneyo yokuvelisa, uhlalutyo lobugcisa kufuneka luqhutywe ngokusekelwe kwimizobo yoyilo lwasekuqaleni olubonelelwe ngumthengi kunye nephepha lemibuzo lemeko yokusetyenziswa kwendawo yegraphite rotors ezaliswe. i-rotor. Umbhobho ojikelezayo we-rotor yegraphite yenziwe ngegraphite ephezulu-yobunyulu, kunye nesakhiwo sayo asiyi kuqwalasela kuphela umsebenzi wamaqamza asasazayo, kodwa isebenzisa ngokupheleleyo amandla e-centrifugal eveliswa ngokuxhokonxa ingxubevange ye-aluminiyam yokunyibilika ukwenza ukunyibilika kungene embhobhoni kwaye ngokulungeleleneyo ukuxuba kunye ne-horizontally etshizwe ngokutshizwa kwerhasi kunye nokuqukuqela kwerhasi yoqhagamshelwano kunye nexesha elikhulayo loqhagamshelwano kunye negesi ephumayo. amaqamza kunye ne-aluminium alloy liquid, ngaloo ndlela iphucula i-degassing kunye nesiphumo sokucoca.
I-rotor yegraphite inoluhlu olubanzi lweenkcazo kwaye ifanelekileΦ 70mm ~ 250mm rotor kunyeΦ I-Impeller ene-diameter ye-85mm ukuya kwi-350mm. Ukucoceka okuphezulu kwe-graphite rotor ineempawu zamandla aphezulu, ukumelana nobushushu obuphezulu, kunye ne-aluminium flow flow corrosion resistance, enokusebenza ngokuzinzileyo kwiindawo ezinobushushu obuphezulu.
Cukuqukwa
Isishwankathelo, ii-rotors zegraphite zokuphosa i-aluminium zidlala indima ebalulekileyo kwi-aluminium alloy casting, ukuphucula umgangatho kunye nokuzinza kwe-aluminium alloy casting ngokucoca inyibiliko ye-aluminium. I-rotors ye-graphite inobomi obude benkonzo kunye nokusebenza okuphezulu kwe-degassing kunye nokucoca, okunokunciphisa iindleko zokucubungula, ukusetyenziswa kwegesi ye-inert, kunye nomxholo we-aluminium kwi-slag, ukuphucula ukusebenza kakuhle kunye nokuveliswa kweendleko. Ngoyilo olufanelekileyo kunye nokukhethwa kwezinto ezifanelekileyo, iirotor zegraphite zinokuhlangabezana neemfuno ezahlukeneyo zemigca yokuvelisa i-aluminium alloy, ukubonelela ngenkxaso ethembekileyo kunye nesiqinisekiso sokuphuhliswa kweshishini lokuphosa i-aluminium. Ngenkqubela phambili eqhubekayo yobugcisa bokuvelisa, i-graphite rotors ye-aluminium casting iya kuqhubeka idlala indima ebalulekileyo kwintsimi ye-aluminium alloy casting, iqhube uphuhliso oluqhubekayo kunye nokutsha kolu shishino.
