Intshayelelo: Iicrucibles zegraphite zinokwahlulwa ngokweendidi ezine.
1.I-crucible ye-graphite ecocekileyo.Iumxholo wekhabhonibukhulu kune99.9%, kwaye yenziwe ngezinto ezicocekileyo ezenziwe ngegraphite.Kucetyiswa kuphela ukusebenzisa ezinye iintlobo zesithando somlilo ngononopheloamaziko ombane.
2.I-Clay graphite crucible.Yenziwe ngomgubo we-graphite wendalo oxutywe nodongwe kunye nezinye izinto ezichasene ne-oxidation ye-binder, kwaye yenziwe ngokujikelezayo.Ilungele iifektri ezineliindleko zomsebenzikwayeizinga lokusebenza eliphantsi.
3.I-Silicon carbide graphite crucible, eyenziwe ngokujikelezayo.Yenziwe nge-graphite powder yendalo, i-silicon carbide, i-aluminium oxide, njl.Ubomi benkonzo malunga namaxesha angama-3-8 kwi-crucible ye-graphite yodongwe.Ubuninzi bobuninzi buphakathi kwe-1.78-1.9.Ifanelekileuvavanyo lobushushu eliphezulu ukunyibilika, imfuno ethandwayo.
I-4.I-silicon carbide graphite crucible yenziwa ngokucinezelwa kwe-isostatic, kwaye i-crucible icinezelwe ngumshini wokucofa isostatic.Ubomi benkonzo ngokuqhelekileyo buyi-2-4 amaxesha e-rotary eyenziwe nge-silicon carbide graphite crucible.Yeyona ifanelekileyoaluminiyamkwayei-zinc oxide.Ezinye iintsimbi kufuneka zikhethwe ngokucophelela, kwaye iifurnaces ze-induction kufuneka zikhethwe ngokucophelela.Ngenxa yeendleko eziphezulu zokucinezelwa kwe-isostatic, ngokuqhelekileyo akukho crucible encinci.

Iindidi zeziko lezinto ezinqamlezileyo:iziko le-coke, iziko leoli, iziko legesi yendalo, isithando somlilo, medium frequency induction eziko(nceda uqaphele ukuba ukunyibilika kokunyibilika kwe-aluminium akuphezulu), i-biological particle furnace, njl. Ifanelekile ukunyibilikisa ubhedu, igolide, isilivere, i-zinc, i-aluminium, i-lead, i-iron cast kunye nezinye isinyithi ezingenayo i-ferrous.Kwakunye ne-asidi engeyiyo eyomeleleyo kunye neekhemikhali ezomeleleyo zealkali ngeubumanzi obuphantsi, ukumelana nomhlwakwayeukumelana nobushushu obuphezulu.
Imiyalelo yokusetyenziswa kwe-graphite crucible (nceda ufunde ngononophelo ngaphambi kokusetyenziswa):
1.I-crucible igcinwa kwi-angenisa umoyakwayeyomileokusingqongileyo ukuphepha ukuchatshazelwa kukufuma.
2. I-crucible kufuneka iphathwe ngokunyamekela, inqatshelwe ngokungqongqo ukuhla kunye nokugubha, kwaye ungaqhubeki, ukuze ungonakalisi umgca wokukhusela phezu kobuso be-crucible.
3. Bhaka i-crucible kwangaphambili ngaphambi kokusetyenziswa.Iqondo lokushisa lokubhaka linyuka ngokuthe ngcembe ukusuka kwi-low ukuya phezulu, kwaye i-crucible iguqulwa rhoqo ukuze ivumele ukuba ifudumale ngokulinganayo, isuse umswakama kwi-crucible, kwaye ngokuthe ngcembe ikhulise ukushisa kwangaphambili ukuya kuma-500 (njengokufudumala).Engafanelekanga, ebangela ukuba i-crucible ikhuphe kwaye iqhume, ayiyiyo ingxaki yomgangatho kwaye ayiyi kubuyiselwa)
4. I-oven crucible kufuneka ihambelane ne-crucible, izithuba eziphezulu kunye nezantsi kunye nezijikelezileyo kufuneka zihlangabezane neemfuno, kwayeisigqumathelo sesithando somlilo akufuneki sicinezelwe kumzimba obethelelweyo.
5. Gwema inaliti yomlilo ngokuthe ngqo kumzimba onqamlekileyo ngexesha lokusetyenziswa, kwaye kufuneka kube njaloitshizwe ngakwisiseko se-crucible.
6. Xa ufaka imathiriyeli, kufuneka yongezwe kancinci, kukhethwaizinto ezityumkileyo.Musa ukupakisha kakhulu okanye uqiniswe kakhulu kwizinto ze-aniseed, ukwenzela ukuba ungagqabhuki i-crucible.
7. Iingcingo ezinqamlekileyo ezisetyenziselwa ukulayishwa kunye nokukhutshwa kufuneka zihambelane nemilo ye-crucible, ukwenzela ukuba ingonakalisi i-crucible.
8. Kungcono ukubasebenzisa i-crucible ngokuqhubekayo, ukuze wenze ngcono ukusebenza kwayo okuphezulu.
9. Ngethuba lenkqubo yokunyibilikisa, inani legalelo lei-arhente kufuneka ilawulwe.Ukusetyenziswa ngokugqithiseleyo kuya kunciphisa ubomi benkonzo ye-crucible.
10. Xa usebenzisa i-crucible,jikelezisa i-crucible ngamaxeshaukuyenza ishushu ngokulinganayo kwaye yandise ukusetyenziswa.
11.Cofa kancincixa ususa i-slag kunye ne-coke kwiindonga zangaphakathi nangaphandle ze-crucible ukuphepha umonakalo kwi-crucible.
12. Ukusetyenziswa kwe-solvent ye-graphite crucible:
I-1) Ingqalelo kufuneka ihlawulwe xa ukongeza i-solvent:i-solvent kufuneka yongezwe kwintsimbi etyhidiweyo, kwaye kunqatshelwe ngokungqongqo ukongeza i-solvent kwisitya esingenanto okanye ngaphambi kokuba isinyithi sinyibilike: gxobhoza isinyithi esityhidiweyo ngokukhawuleza emva kokufaka isinyithi esityhidiweyo.
2) Indlela yokujoyina:
a.Izinyibilikisi ngumgubo, isambuku, kunye nengxubevange yesinyithi.
b, igama lesicelo esikhulu liyanyibilikaembindini webhola ekhatywayokwayeisinye kwisithathu sendawo engaphezulu komphezulu ongezantsi.
c.I-flux engumgubo kufuneka yongezwe kuyogwema ukudibana ngokuthe ngqo nodonga lwe-crucible.d.Yiinqatshelwe ngokungqongqo ukuba umsinga usasazwe kwiziko lokunyibilikisa, kungenjaloiya kuludiliza udonga olungaphandleye crucible.
e, Imali eyongeziweyo yiimali encinciichazwe ngumvelisi.
f.Emva kokuba i-arhente yokucoca kunye ne-modifier yongezwa, isinyithi esityhidiweyokufuneka isetyenziswe ngokukhawuleza.
g, qinisekisa ukuba kusetyenziswa umbane ochanekileyo.Ukhukuliseko lwe-flux kwicrucible yegraphite Ukulungiswa kokhukuliseko lwesilungisi: I-fluoride kwisilungisi sokusulungekisa iya kukhukulisa i-crucible ukusuka kwindawo engezantsi (R) yodonga olungaphandle lwe-crucible.
Umhlwa: I-slag encangathi ebethelelweyo kufuneka ibezicocwe yonke imihlaekupheleni kweshifti.Ukuwohloka okungaphendulwanga kuya kubhaptizwa kwi-slag kwaye isasazeke kwi-crucible, ukwandisa umngcipheko wokuphucula ukuchithwa kunye nokuguguleka.Iqondo lobushushu kunye nesantya somhlwa: Ireyithi yokusabela kwi-crucible kunye ne-arhente yokucoca ilingana nobushushu.Ukwandisa ubushushu obuphezulu obungeyomfuneko be-alloy liquid iya kunciphisa kakhulu ubomi be-crucible.I-Corrosion ye-aluminium ash kunye ne-aluminium slag: Kwi-aluminium ash equkethe ityuwa ye-sodium enzulu kunye netyuwa ye-phosphorus, imeko ye-corrosion ifana nale ngasentla, eya kunciphisa kakhulu ubomi be-crucible.Ukhukuliseko lwesilungisi kunye nolwelo olulungileyo: Xa isilungisi esinolwelo olulungileyo songezwa, isinyithi esinyibilikisiweyo kufuneka sishukunyiswe ngokukhawuleza ukuze singakwazi ukunxibelelana nomzimba wembiza.
13. Isixhobo sokucoca i-Graphite Crucible Slag Cleaning: Isixhobo sijikelezwe nge-curvature efana nodonga lwangaphakathi lwebhodwe elisetyenzisiweyo.Ukukhutshwa kokuqala: Emva kokufudumeza kokuqala kunye nokusetyenziswa, ukukhutshwa kwe-slag eveliswayo kuyona nto ibalulekileyo.I-slag eveliswa okokuqala ithambile kakhulu, kodwa emva kokuba ishiywe, iba nzima kakhulu kwaye kunzima ukuyisusa.Ixesha Lokucoca:Nangona i-crucible isatshisa kwaye i-slag ithambile, kufuneka ihlanjululwe imihla ngemihla.
