Iintsimbi zegraphiteube ne-conductivity entle ye-thermal kunye nokumelana nobushushu obuphezulu. Ngexesha lokusetyenziswa kobushushu obuphezulu, i-coefficient yabo yokwandiswa kwe-thermal incinci, kwaye banokumelana noxinzelelo oluthile lokufudumeza ngokukhawuleza kunye nokupholisa. Ukuxhathisa okuqinileyo kwe-corrosion kwizisombululo ze-asidi kunye ne-alkaline, kunye nokuzinza kweekhemikhali okugqwesileyo.
Iimpawu zeemveliso ze-graphite crucible
1. Utyalo-mali oluphantsi, i-graphite crucibles ixabisa malunga ne-40% ephantsi kuneziko ezifanayo.
2. Abasebenzisi abafuni ukuvelisa isithando somlilo, kwaye isebe lethu lezoshishino libonelela ngesethi epheleleyo yoyilo kunye nokuveliswa.
3. Ukusetyenziswa kwamandla aphantsi, ngenxa yoyilo olufanelekileyo, ulwakhiwo oluphezulu, izinto zenoveli, kunye nokusetyenziswa kwamandla okuvavanywa kwee-graphite crucibles xa kuthelekiswa neziko ezifanayo zemodeli efanayo.
4. Ungcoliseko oluncinci, njengamandla acocekileyo afana nerhasi yendalo okanye irhasi enyibilikisiweyo ingasetyenziswa njengamafutha, okukhokelela kungcoliseko oluncinci.
5. Ukusebenza kakuhle kunye nokulawula, ngokude nje ukuba i-valve ilungiswe ngokuhambelana nokushisa kwesithando somlilo.
6. Umgangatho wemveliso uphezulu, kwaye ngenxa yokusebenza kakuhle kunye nokulawula, kunye nendawo efanelekileyo yokusebenza, umgangatho wemveliso uqinisekisiwe.
7. Amandla anoluhlu olubanzi lwezicelo, ezingasetyenziselwa ngokubanzi igesi yendalo, igesi yamalahle, i-liquefied gas, ioli enzima, i-diesel, njl njl. Ingasetyenziselwa amalahle kunye ne-coke emva kokuguqulwa okulula.
I-8.I-graphite crucible furnace inoluhlu olubanzi lwezicelo zokushisa, ezinokuncibilika, zifakwe kwi-insulated, okanye zombini zinokusetyenziswa kunye.
Ukusebenza kobugcisa becrucible yegraphite:
1. Uluhlu lweqondo lokushisa lesithando 300-1000
2. Umthamo wokunyibilika we-crucible (esekelwe kwi-aluminium) ukusuka kwi-30kg ukuya kwi-560kg.
3. Ukuveliswa kwamafutha kunye nobushushu: 8600 calories / m yegesi yendalo.
4. Ukusetyenziswa kwepetroli enkulu kwi-aluminium etyhidiweyo: i-0.1 igesi yendalo ngekhilogram ye-aluminium.
5. Ixesha lokunyibilika: 35-150 imizuzu.
Ilungele ukunyibilikisa iintsimbi ezahlukeneyo ezingezizo intsimbi ezifana negolide, isilivere, ubhedu, ialuminiyam, ilothe, i-zinc, kunye nentsimbi yekhabhoni ephakathi kunye neentsimbi ezahlukeneyo ezinqabileyo.
Ukusebenza ngokomzimba: Ukumelana nomlilo ≥ 16500C; I-porosity ebonakalayo ≤ 30%; Ubuninzi bomthamo ≥ 1.7g / cm3; Amandla oxinzelelo ≥ 8.5MPa
Ukubunjwa kweekhemikhali: C: 20-45%; I-SIC: 1-40%; AL2O3: 2-20%; SIO2: 3-38%
I-crucible nganye imele i-1 kilogram yobhedu olutyhidiweyo.
Injongo ye-graphite crucible:
I-graphite crucible yinqanawa ephikisayo eyenziwe nge-graphite yendalo ye-flake, ilitye le-wax, i-silicon carbide kunye nezinye izinto ezisetyenziselwa ukunyibilikisa kunye nokuphosa ubhedu, i-aluminium, i-zinc, i-lead, igolide, isilivere, kunye neentlobo ezahlukeneyo zesinyithi ezinqabileyo.
Imiyalelo yokusebenzisa iimveliso ze-crucible
1. Inani elichaziweyo le-crucible ngumthamo wobhedu (#/kg)
2. I-graphite crucibles kufuneka igcinwe kude nomswakama kwaye kufuneka igcinwe kwindawo eyomileyo okanye kwisakhelo somthi.
3. Phatha ngononophelo ngexesha lokuthutha kwaye unqande ngokungqongqo ukuwa okanye ukugubha.
4. Ngaphambi kokusetyenziswa, kuyimfuneko ukutshisa ukubhaka kwisixhobo sokumisa okanye ngesithando somlilo, kunye neqondo lokushisa ngokuthe ngcembe linyuka ukuya kuma-500 ℃.
5. I-crucible kufuneka ibekwe ngaphantsi kwendawo yomlomo wesithando somlilo ukuze ugweme ukugqoka kunye nokukrazula kwikhava yesithando somlilo.
6. Xa ukongeza izinto eziphathekayo, kufuneka kusekelwe kwi-solubility ye-crucible, kwaye izinto ezininzi akufanele zongezwe ukuphepha ukwandiswa kwe-crucible.
7. Isixhobo sokukhupha kunye ne-crucible clamp kufuneka ihambelane nesimo se-crucible, kwaye inxalenye ephakathi kufuneka igxininiswe ukuphepha umonakalo wamandla wendawo kwi-crucible.
8. Xa ususa i-slag kunye ne-coke kwiindonga zangaphakathi nangaphandle ze-crucible, kufuneka zibethelwe ngobumnene ukuphepha ukulimaza i-crucible.
9. Umgama ofanelekileyo kufuneka ugcinwe phakathi kwe-crucible kunye nodonga lwesithando somlilo, kwaye i-crucible kufuneka ifakwe phakathi kweziko.
10. Ukusetyenziswa kwezinto ezivuthayo ezivuthayo kunye nezongezo ziya kunciphisa ubomi benkonzo ye-crucible.
11. Ngethuba lokusetyenziswa, ukujikeleza i-crucible kanye ngeveki kunokwandisa ubomi bayo benkonzo.
12. Gwema ukutshiza ngokuthe ngqo amadangatye e-oxidation eqinile emacaleni nangaphantsi kwe-crucible.
