I-graphite cruciblesube ne-conductivity enhle yokushisa kanye nokumelana nokushisa okuphezulu. Ngesikhathi sokusebenzisa izinga lokushisa eliphezulu, i-coefficient yabo yokwandisa ukushisa incane, futhi banokuphikiswa okuthile kokushisa nokupholisa ngokushesha. Ukumelana nokugqwala okuqinile kuzixazululo ze-asidi ne-alkaline, ezinokuqina okuhle kakhulu kwamakhemikhali.
Izici zemikhiqizo ye-graphite crucible
1. Ukutshalwa kwezimali okuphansi, ama-graphite crucibles anenani elilinganiselwa ku-40% eliphansi kunezithando zomlilo ezifanayo.
2. Abasebenzisi abadingi ukukhiqiza isithando somlilo, futhi umnyango wethu webhizinisi uhlinzeka ngesethi ephelele yokuklama nokukhiqiza.
3. Ukusetshenziswa kwamandla okuphansi, ngenxa yedizayini enengqondo, isakhiwo esithuthukisiwe, izinto zenoveli, kanye nokusetshenziswa kwamandla okuhloliwe kwama-graphite crucibles uma kuqhathaniswa neziko elifanayo lemodeli efanayo.
4. Ukungcola okuncane, njengoba amandla ahlanzekile njengegesi yemvelo noma igesi eliwuketshezi engasetshenziswa njengophethiloli, okuholela ekungcoleni okuncane.
5. Ukusebenza nokulawula okulula, inqobo nje uma i-valve ilungiswa ngokuvumelana nokushisa kwesithando somlilo.
6. Ikhwalithi yomkhiqizo iphezulu, futhi ngenxa yokusebenza okulula nokulawula, nendawo yokusebenza enhle, ikhwalithi yomkhiqizo iqinisekisiwe.
7. Amandla anezinhlobonhlobo zezicelo, ezingasetshenziswa kabanzi kugesi yemvelo, igesi yamalahle, igesi eliwuketshezi, uwoyela osindayo, udizili, njll. Angasetshenziswa futhi kumalahle necoke ngemva kokuguqulwa okulula.
I-8.I-graphite crucible furnace inezinhlobo eziningi zezicelo zokushisa, ezingancibilika, zifakwe insulated, noma zombili zingasetshenziswa ndawonye.
Ukusebenza kobuchwepheshe kwe-graphite crucible:
1. Ibanga lokushisa lesithando somlilo 300-1000
2. Umthamo wokuncibilika we-crucible (ngokusekelwe ku-aluminium) usukela ku-30kg kuya ku-560kg.
3. Ukukhiqizwa kukaphethiloli nokushisa: 8600 kilojoule/m yegesi yemvelo.
4. Ukusetshenziswa kukaphethiloli okukhulu kwe-aluminium encibilikisiwe: 0.1 igesi yemvelo ngekhilogremu ye-aluminium.
5. Isikhathi sokuncibilika: imizuzu engu-35-150.
Ifanele ukuncibilikisa izinsimbi ezihlukahlukene ezingezona ayoni njengegolide, isiliva, ithusi, i-aluminium, umthofu, i-zinc, kanye nensimbi ye-carbon ephakathi nezinsimbi ezihlukahlukene ezingavamile.
Ukusebenza ngokomzimba: Ukumelana nomlilo ≥ 16500C; I-porosity ebonakalayo ≤ 30%; Ukuminyana kwevolumu ≥ 1.7g/cm3; Amandla okucindezela ≥ 8.5MPa
Ukwakhiwa kwamakhemikhali: C: 20-45%; I-SIC: 1-40%; I-AL2O3: 2-20%; I-SIO2: 3-38%
I-crucible ngayinye imelela ikhilogremu engu-1 yethusi elincibilikisiwe.
Inhloso ye-graphite crucible:
I-graphite crucible iyisitsha esiphikisayo esenziwe nge-graphite ye-flake yemvelo, itshe le-wax, i-silicon carbide nezinye izinto zokusetshenziswa, ezisetshenziselwa ukuncibilikisa nokuphonsa ithusi, i-aluminium, i-zinc, i-lead, igolide, isiliva, nezinsimbi ezihlukahlukene ezingavamile.
Imiyalo yokusebenzisa imikhiqizo ye-crucible
1. Inombolo ecacisiwe ye-crucible umthamo wethusi (#/kg)
2. I-graphite crucibles kufanele igcinwe kude nomswakama futhi kufanele igcinwe endaweni eyomile noma kuhlaka lwamapulangwe.
3. Phatha ngokucophelela ngesikhathi sokuthutha futhi ukwenqabele ngokuqinile ukuwa noma ukunyakazisa.
4. Ngaphambi kokusetshenziswa, kuyadingeka ukushisa ukubhaka kumshini wokomisa noma ngesithando somlilo, izinga lokushisa likhuphuka kancane kancane libe ngu-500 ℃.
5. I-crucible kufanele ibekwe ngaphansi kobuso bomlomo wesithando somlilo ukuze ugweme ukuguga nokudilika kwesembozo sesithando somlilo.
6. Uma ungeza izinto zokwakha, kufanele kusekelwe ekuncibilikeni kwe-crucible, futhi izinto eziningi kakhulu akufanele zengezwe ukuze kugwenywe ukunwetshwa kwe-crucible.
7. Ithuluzi lokukhipha kanye ne-crucible clamp kufanele ihambisane nokuma kwe-crucible, futhi ingxenye ephakathi kufanele iboshwe ukuze kugwenywe ukulimala kwamandla wendawo ku-crucible.
8. Uma ususa i-slag ne-coke ezindongeni zangaphakathi nangaphandle ze-crucible, kufanele ingqongqoze ngobumnene ukuze igweme ukulimaza i-crucible.
9. Ibanga elifanele kufanele ligcinwe phakathi kwe-crucible kanye nodonga lwesithando somlilo, futhi i-crucible kufanele ibekwe phakathi nendawo yesithando somlilo.
10. Ukusetshenziswa kwezinsiza ezivuthayo nezithasiselo kuzonciphisa impilo yesevisi ye-crucible.
11. Ngesikhathi sokusetshenziswa, ukuzungezisa i-crucible kanye ngesonto kungandisa impilo yayo yesevisi.
12. Gwema ukufafaza okuqondile kwamalangabi e-oxidation aqinile emaceleni nangaphansi kwe-crucible.
