I-graphite crucibleI-silicon carbide graphite crucibleiyisitsha esenziwe nge-graphite njengento eluhlaza, ngakho-ke inokumelana okuhle kakhulu nokushisa okuphezulu futhi ingasetshenziswa ekuncibilikiseni insimbi yezimboni noma ukuphonsa.Isibonelo, empilweni yansuku zonke, ungaqonda ukuthi kuvame ukuba nabathengisi ezindaweni zasemaphandleni abalungisa izimbiza ze-aluminium noma izimbiza ze-aluminium.Amathuluzi abawasebenzisayo angama-crucible.Amashidi e-aluminium afakwa ku-crucible futhi ashiswe ngomlilo aze ancibilike emanzini e-aluminium, Thela futhi emfantwini webhodwe, uyipholise phansi, bese ingasetshenziswa.Kodwa-ke, ama-graphite crucibles kanye ne-silicon carbide crucibles asetshenziswa embonini.Phakathi kwazo, ama-graphite crucibles ane-conductivity enhle yokushisa, kodwa athambekele ekuhlanganiseni ne-oxidation futhi anezinga eliphezulu lokulimala.I-silicon carbide graphite crucibles inomthamo omkhulu nempilo yesevisi ende kunezikhilimu ze-graphite.Sekuyiminyaka engu-40 sisebenza ngokukhethekile ekuthengisweni nasekukhiqizeni ama-crucibles.Ama-graphite crucibles esiwakhiqizayo afaneleka kakhulu ukuncibilikisa igolide, isiliva, ithusi, insimbi, i-aluminium, i-zinc, nethini, kanye nezindlela ezihlukahlukene zokuncibilikisa nokushisisa njenge-coke, isithando somlilo sikawoyela, igesi yemvelo, isithando somlilo sikagesi, njll. ama-graphite crucible esiwakhayo adunyiswa kakhulu ngamakhasimende amasha namadala ngekhwalithi yawo enhle nokusebenza okuzinzile.Siphinde sethule ubuchwepheshe obuthuthukisiwe bokubumba i-crucible - isostatic pressure crucible form forming - esekelwe ezimakethe nezidingo zamakhasimende, Futhi uhlelo oluqinile lokuhlola ukuqinisekiswa kwekhwalithi, i-silicon carbide crucible ekhiqizwa lobu buchwepheshe inezici zokuminyana kwevolumu ephezulu, ukumelana nokushisa okuphezulu, okusheshayo. I-thermal conductivity, ukumelana ne-asidi kanye ne-alkali corrosion, amandla okushisa aphezulu, nokumelana okuphezulu kwe-oxidation.Impilo yayo yesevisi iphindwe izikhathi ezi-3-5 kunezinsimbi ze-graphite.Ngesikhathi esifanayo, yonga uphethiloli futhi inciphisa ukushuba kwezisebenzi.Intengo yeziphambano ze-isostatic pressure crucibles ezonga amandla kanye neziphambano ze-isostatic pressure crucibles zenza lo mkhiqizo usebenze kabanzi ekuncibilikisweni kwezinsimbi ezingenayo insimbi.
I-graphite crucibles ingasetshenziswa ezithandweni ezihlukahlukene, njengeziko likagesi, izithando zomlilo eziphakathi nendawo, iziko legesi, iziko, njll., ukuncibilikisa igolide, isiliva, ithusi, insimbi, i-aluminium, i-zinc, ithini, nama-alloys.Indlela yokufaka elungile ye-graphite crucible ne-silicon carbide crucible
1. Isisekelo se-graphite crucible sidinga ukuba nobubanzi obufanayo noma obukhudlwana njengendawo ephansi ye-crucible, futhi ubude beplathifomu yokubethelwa kumele bube phezulu kunobhobho ukuze kuvinjwe umlilo ukuthi ungafafazi ku-crucible.
2. Uma usebenzisa izitini eziphikisayo njengamatafula e-crucible, izitini eziyindilinga eziphikisayo kufanele zisetshenziswe, eziyisicaba futhi ezingagobile.Ungasebenzisi izinto zezitini eziyingxenye noma ezingalingani.Kungcono ukusebenzisa amatafula e-graphite crucible angenisiwe.
3. Ithebula le-crucible kufanele libekwe endaweni ephakathi yokuncibilika nokuncibilika, nge-coke powder, umlotha wotshani, noma ukotini ophikisayo njengephedi ukuze kugwenywe ukunamathela phakathi kwe-crucible kanye netafula lokudilika.Ngemuva kokubeka i-crucible, kufanele ibe yizinga.
4. Ubukhulu phakathi kwe-crucible kanye nomzimba wesithando somlilo kufanele bufane, futhi ibanga phakathi kwe-crucible nodonga oluncibilikayo kufanele lufanele, okungenani u-40mm noma ngaphezulu.
Lapho kulayishwa i-crucible enoqhwaku esithandweni somlilo, igebe elicishe libe ngu-30-50MM kufanele ligcinwe phakathi kwephansi lembobo ebhobokayo kanye nesitini esiphikisayo, futhi kungafakwa lutho ngaphansi.I-nozzle kanye nodonga lwesithando somlilo kufanele busheleleke ngekotini eliphikisayo.Udonga lwesithando somlilo ludinga ukuba nezitini ezingaguquki eziphikisayo futhi i-crucible idinga ukugxunyekwa ngekhadibhodi likathayela elinogqinsi olungaba ngu-3mm njengendawo yokunwetshwa okushisayo ngemva kokufudumeza.
Ubuchwepheshe bokukhiqiza ama-graphite crucibles bubonakala ikakhulukazi ezicini ezifana nefomula, izinto zokusetshenziswa, izinto zokukhiqiza, kanye nobuchwepheshe.Mayelana nokukhethwa kwempahla eluhlaza, sisebenzisa ngokuyinhloko ubumba oluphikisayo, ama-aggregates, i-graphite yemvelo, njll. Ngokusho kwemisebenzi ehlukene ye-crucible ngayinye, izithako namafomula esiwakhethayo nawo ahlukile, ikakhulukazi aboniswa ngezilinganiso ezahlukene zezinto zokusetshenziswa ezihlukahlukene.Indlela iwukubumba ngokucindezelwa, ukubumba okujikelezayo, nokubumba ngesandla, okuwukubumba kwe-graphite.Ngemuva kokwenza ukubunjwa, kubalulekile ukukhumbula ukuwomisa.Ngemuva kokuhlolwa, ifanelekile, futhi imikhiqizo efanelekayo ingacwebezelwa
