Intshayelelo: Iicrucibles zegraphite zinokwahlulwa ngokweendidi ezine.
1.I-crucible ye-graphite ecocekileyo.Umxholo wekhabhoni ungaphezulu kwe-99.9%, kwaye yenziwe ngezinto ezicocekileyo ezenziwe ngegraphite.Kucetyiswa kuphela ukusebenzisa ezinye iintlobo zesithando somlilo ngokucokisekileyo kwiziko zombane.
2.I-Clay graphite crucible.Yenziwe ngomgubo we-graphite wendalo oxutywe nodongwe kunye nezinye izinto ezichasene ne-oxidation ye-binder, kwaye yenziwe ngokujikelezayo.Ifanelekile kwiifektri ezinexabiso eliphantsi lomsebenzi kunye nezinga eliphantsi lokusebenza.
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.Ilungele ukunyibilikiswa kovavanyo lobushushu obuphezulu, imfuno edumileyo.
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.Iyona nto ifanelekileyo kwi-aluminium kunye ne-zinc oxide.Ezinye iintsimbi kufuneka zikhethwe ngokucophelela, kwaye iifurnaces ze-induction kufuneka zikhethwe ngokucophelela.Ngenxa yeendleko eziphezulu zokucinezelwa kwe-isostatic, ngokuqhelekileyo akukho crucible encinci.

Iintlobo zesithando somlilo se-crucibles: i-coke furnace, i-oil furnace, i-furnace yokumelana, i-medium frequency induction furnace (nceda uqaphele ukuba ukunyibilika kokunyibilika kwe-aluminium akukho phezulu), i-biological particle furnace, njl. Ifanelekile ukunyibilikisa ubhedu, igolide, isilivere. , i-zinc, i-aluminiyam, ilothe, isinyithi esityhidiweyo kunye nezinye izinyithi ezingenayo i-ferrous.Kwakunye ne-asidi engeyiyo eyomeleleyo kunye neekhemikhali zealkali ezinamandla ezinobumanzi obuphantsi, ukuxhathisa ukubola kunye nokumelana nobushushu obuphezulu.
Imiyalelo yokusetyenziswa kwe-graphite crucible (nceda ufunde ngononophelo ngaphambi kokusetyenziswa):
I-1.I-crucible igcinwe kwindawo enomoya kunye neyomileyo ukuze igweme ukuchatshazelwa ngumswakama.
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. Isithando somlilo esinqamlekileyo kufuneka sihambelane ne-crucible, izithuba eziphezulu kunye nezantsi kunye nezijikelezileyo kufuneka zihlangabezane neemfuno, kwaye isigqubuthelo somlilo akufanele sicinezelwe kumzimba onqamlekileyo.
5. Gwema inaliti yomlilo ngokuthe ngqo kumzimba onqamlekileyo ngexesha lokusetyenziswa, kwaye kufuneka utshizwe ngokubhekiselele kwisiseko se-crucible.
6. Xa ukongeza izinto, kufuneka zongezwe ngokucothayo, kukhethwa izinto 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 ukusebenzisa i-crucible ngokuqhubekayo, ukwenzela ukuba wenze ngcono ukusebenza kwayo okuphezulu.
9. Ngethuba lenkqubo ye-smelting, inani legalelo le-arhente kufuneka lilawulwe.Ukusetyenziswa ngokugqithiseleyo kuya kunciphisa ubomi benkonzo ye-crucible.
10. Xa usebenzisa i-crucible, ujikeleze i-crucible ngezikhathi ezithile ukuze ufudumale ngokulinganayo kwaye wandise ukusetyenziswa.
11. Thepha ngokukhawuleza xa ususa i-slag kunye ne-coke kwiindonga zangaphakathi nangaphandle ze-crucible ukuze ugweme umonakalo kwi-crucible.
12. Ukusetyenziswa kwe-solvent ye-graphite crucible:
I-1) Ingqalelo kufuneka ihlawulwe xa idibanisa i-solvent: i-solvent kufuneka yongezwe kwintsimbi etyhidiweyo, kwaye inqatshelwe ngokungqongqo ukongeza i-solvent embizeni engenanto okanye ngaphambi kokuba isinyithi sinyibilike: gxobhoza isinyithi esityhidiweyo ngokukhawuleza emva kokufaka i-solvent. intsimbi.
2) Indlela yokujoyina:
a.Izinyibilikisi ngumgubo, isambuku, kunye nengxubevange yesinyithi.
b, igama lesicelo sobuninzi liyanyibilika kumbindi we-crucible kunye nesinye kwisithathu sendawo engaphezulu komphezulu ongezantsi.
c.I-powdered flux kufuneka yongezwe ukuze ugweme ukudibanisa ngokuthe ngqo nodonga lwe-crucible.d.Kunqatshelwe ngokungqongqo ukuba i-flux ihlakazeke kwisithando somlilo esinyibilikayo, ngaphandle koko iya kutshabalalisa udonga lwangaphandle lwe-crucible.
e, Imali eyongeziweyo yimali encinci echazwe ngumvelisi.
f.Emva kokuba i-arhente yokucoca kunye ne-modifier yongezwa, isinyithi esityhidiweyo kufuneka sisetyenziswe 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.
Ukonakala: I-crucible sticky slag kufuneka icocwe yonke imihla ekupheleni 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: Ngelixa i-crucible isatshisa kwaye i-slag ithambile, kufuneka ihlanjululwe yonke imihla.
