I-Graphite crucibleI-silicon carbide graphite cruciblesisikhongozelo esenziwe ngegraphite njengento ekrwada, ke sinokumelana nobushushu obuphezulu kwaye sinokusetyenziswa kwimizi-mveliso yokunyibilikisa isinyithi okanye ukuphosa. Ngokomzekelo, kubomi bemihla ngemihla, unokuqonda ukuba kukho abathengisi kwiindawo ezisemaphandleni abalungisa izimbiza ze-aluminium okanye izimbiza ze-aluminium. Izixhobo abazisebenzisayo zizibonda. Amaphepha e-aluminiyam afakwe kwi-crucible kwaye atshiswe ngomlilo ade anyibilike emanzini e-aluminium, ugalele kwakhona kwi-crack yembiza, uyipholise phantsi, kwaye ingasetyenziswa. Nangona kunjalo, i-graphite crucibles kunye ne-silicon carbide crucibles zisetyenziswa kwishishini. Phakathi kwazo, i-graphite crucibles ine-conductivity enhle ye-thermal, kodwa i-oxidation ixhomekeke kwi-oxidation kwaye inezinga eliphezulu lomonakalo. I-silicon carbide graphite crucibles inomthamo omkhulu kunye nobomi benkonzo obude kuneentsimbi zegraphite. Siye sikhethekileyo ekuthengiseni nasekuveliseni ii-crucibles iminyaka engama-40. I-graphite crucibles esiyivelisayo ifanelekile ngokubanzi ukunyibilikisa igolide, isilivere, ubhedu, isinyithi, i-aluminiyam, i-zinc, kunye ne-tin, kunye neendlela ezahlukeneyo zokunyibilikisa kunye nokufudumeza ezifana ne-coke, i-oil furnace, igesi yendalo, isithando somlilo sombane, njl. iicrucibles zegraphite esizenzayo zidunyiswa kakhulu ngabathengi abatsha kunye nabadala ngomgangatho wabo omhle kunye nokusebenza okuzinzile. Siphinde sazisa ubuchwephesha bokubumba i-crucible crucible - isostatic pressure crucible forming method - esekwe kwiimarike nakwiimfuno zabathengi, kunye nenkqubo engqongqo yovavanyo lokuqinisekisa umgangatho, i-silicon carbide crucible eveliswe yile teknoloji ineempawu zokuxinana komthamo ophezulu, ukumelana nobushushu obuphezulu, ngokukhawuleza. I-thermal conductivity, i-asidi kunye nokumelana ne-alkali corrosion, amandla okushisa aphezulu, kunye nokumelana okuphezulu kwe-oxidation. Ubomi bayo benkonzo buyi-3-5 amaxesha ee-graphite crucibles. Kwangaxeshanye, yonga amafutha kwaye inciphisa ukuqina kwabasebenzi. Ixabiso le-isostatic pressure crucibles yokugcina amandla kunye ne-isostatic pressure crucibles yokulondoloza amandla yenza le mveliso isetyenziswe ngokubanzi kwi-smelting ye-metal non-ferrous.
Iintsimbi zegraphite zingasetyenziswa kwiziko ezahlukahlukeneyo, ezifana neziko lombane, iziko eliphakathi, iziko legesi, iitoni, njl. Indlela yokufakela echanekileyo ye-graphite crucible kunye ne-silicon carbide crucible
1. Isiseko se-graphite crucible kufuneka sibe nobubanzi obufanayo okanye obukhulu njengezantsi kwe-crucible, kwaye ukuphakama kweqonga le-crucible kufuneka libe liphezulu kunombhobho wokukhusela umlilo ukuba ungatshizi kwi-crucible.
2. Xa usebenzisa izitena eziphikisayo njengeetafile ze-crucible, izitena ze-refractory zesetyhula kufuneka zisetyenziswe, ezizicaba kwaye zingagotywanga. Musa ukusebenzisa isiqingatha okanye izinto ezingalinganiyo zezitena. Kungcono ukusebenzisa iitafile ze-graphite crucible.
3. Itafile ye-crucible kufuneka ibekwe kwindawo ephakathi yokunyibilika kunye nokunyibilika, kunye ne-coke powder, i-straw ash, okanye i-cotton refractory njenge-pad ukuze ugweme ukunamathela phakathi kwe-crucible kunye netafile ye-crucible. Emva kokubeka i-crucible, kufuneka ibe kwinqanaba.
4. Ubungakanani phakathi kwe-crucible kunye ne-furnace body kufuneka ihambelane, kwaye umgama phakathi kwe-crucible kunye nodonga olunyibilikayo kufuneka lufaneleke, ubuncinane i-40mm okanye ngaphezulu.
Xa ulayisha i-crucible beaked kwisithando somlilo, i-gap emalunga ne-30-50MM kufuneka igcinwe phakathi komzantsi we-crucible nozzle kunye nesitena esiphikisayo, kwaye akukho nto kufuneka ibekwe ngaphantsi. Umbhobho kunye nodonga lwesithando somlilo kufuneka lulungiswe ngekotoni ephikisayo. Udonga lwesithando somlilo kufuneka lube nezitena ezisisigxina kunye ne-crucible kufuneka ifakwe ngekhadibhodi edibeneyo kunye nobukhulu obumalunga ne-3mm njengendawo yokwandisa i-thermal emva kokufudumeza.
Itekhnoloji yokuvelisa i-graphite crucibles ibonakala ikakhulu kwimiba efana nefomula, izinto ezikrwada, izixhobo zokuvelisa, kunye nobuchwepheshe. Ngokumalunga nokukhethwa kwezinto eziluhlaza, sisebenzisa udongwe olunqabileyo, i-aggregates, i-graphite yendalo, njl. Ngokutsho kwemisebenzi eyahlukeneyo ye-crucible nganye, izithako kunye neefomyula esizikhethayo nazo zihluke, ngokukodwa zibonakaliswa kwimilinganiselo eyahlukeneyo yezinto ezihlukeneyo. Le ndlela ingokubumba ngokucinezela, ukubumba ngokujikeleza, kunye nokubumba ngesandla, okukubumba igraphite. Emva kokwenza ukubunjwa, kubalulekile ukukhumbula ukuwomisa. Emva kokuhlolwa, kuyafaneleka, kwaye iimveliso ezifanelekileyo zinokugqatswa
