Iicrucible zegraphite zodongwe, eyaziwa ngokuba yi-graphite piles okanye iileyile zobhedu ezityhidiweyo, zizixhobo ezibalulekileyo kwintsimi yokunyibilikisa isinyithi. Ezi crucibles zisetyenziselwa ukunyibilikisa iintsimbi ezingenayo i-ferrous ezifana nobhedu, ubhedu, igolide, isilivere, i-zinc, kunye nelothe, kunye ne-alloys yazo. Inkqubo yokwenziwa kodongwe lwe-graphite crucibles ibandakanya ukusetyenziswa kwe-graphite ye-flake yendalo njengeyona nto iphambili, kunye nodongwe kunye nezinye izinto eziphikisayo.
Icandelo lodongwe lwe-crucible kufuneka libe msulwa, libe neplastiki eyomeleleyo, iipropati ezizinzileyo zomzimba kunye neekhemikhali, kwaye zibe ne-refractoriness ephezulu kunye nemiphumo emihle yokushisa. Ngokusebenzisa uchungechunge lokuxuba, ukubumba, kunye namanyathelo okudubula, i-crucible ephezulu yokusebenza iveliswa. Enye yeenzuzo eziphambili ze-graphite crucibles zodongwe kukumelana nomlilo okhethekileyo kunye nokuzinza kwe-thermal. Ubukho begraphite buvumela ezi crucibles ukuba zimelane nobushushu obuphezulu, obubalulekileyo ekuqhubeni iinkqubo zokunyibilikisa isinyithi.
Ngaphezu koko, inxalenye yodongwe ye-crucible ibonelela ngokugqwesileyo kwe-thermal insulation, okubangelwa inkqubo yokunyibilikisa isinyithi efanayo. Oku kugquma kunceda ukugcina amaqondo obushushu aphezulu afunekayo ekunyibilikiseni okusebenzayo. Ukongeza, iicrucibles zodongwe zegraphite zibonisa ukuxhathisa ukothuka kwe-thermal. Oku kuthetha ukuba nangona i-crucible idlula ngokukhawuleza kunye nokutshintsha kobushushu obugqithisileyo ngexesha lenkqubo yokunyibilikisa, inokumelana nokutshitshiswa kwe-thermal kwaye iqinisekise inkqubela phambili egudileyo yokusebenza kwesinyithi.
Ngokumalunga nokuzinza kweekhemikhali, i-crucibles ye-graphite yodongwe ibonisa ukuchasana okulungileyo malunga neempendulo zeekhemikhali kunye nezinyithi ezinyibilikayo. Oku kubalulekile ekugcineni umgangatho kunye nokucoceka kwesinyithi esiveliswayo. Ukuzinza kwe-crucible kuthintela nayiphi na intsebenziswano yeekhemikhali ezingafunekiyo ezinokuphazamisa ingqibelelo yesinyithi.
Ngokubanzi, iicrucibles zodongwe zegraphite zizixhobo ezikhethekileyo zokunyibilikisa isinyithi. Ukumelana nomlilo okugqwesileyo, ukuzinza kwe-thermal, ukuxhathisa ukutshatyalaliswa kwe-thermal, kunye nokuzinza kweekhemikhali kubenza basetyenziswe ngokubanzi kwishishini. Nayiphi na ingcali ebandakanyekayo kwi-metal smelting iyakuqonda ukubaluleka kwezixhobo zokusebenza eziphezulu, kunye ne-clay graphite crucibles ihambelana ngokugqibeleleyo ne-bill. Ngokuhlala kwabo kunye nokusebenza okungaqhelekanga, ezi zityhutyhutyhutyhu zinceda ekuqinisekiseni ukunyibilika okuyimpumelelo kunye nokusebenzayo kwesinyithi esingenawo i-ferrous kunye ne-alloys yazo.
Ukuqukumbela, i-crucibles ye-graphite yodongwe yinto ebalulekileyo kwintsimi ye-metal smelting. Inkqubo yabo yokuvelisa ibandakanya indibaniselwano enononophelo ye-flake yendalo yegraphite, udongwe, kunye nezinye izinto ezichasayo. Ezi crucibles zibonelela ngokugqwesileyo kokumelana nomlilo, ukuzinza kwe-thermal, ukuxhathisa ukothuka kwe-thermal, kunye nokuzinza kweekhemikhali. Ukukwazi kwabo ukumelana namaqondo obushushu aphezulu, ukubonelela ngokugquma kwe-thermal, ukuxhathisa ukothuka kwe-thermal, kunye nokuphepha ukusabela kweekhemikhali kubenza babaluleke kakhulu kwishishini lokunyibilikisa. Ngoko ke, nokuba uncibilikisa ubhedu, ubhedu, igolide, isilivere, i-zinc, i-lead, okanye i-alloys yabo, i-crucibles ye-graphite yodongwe lukhetho oluthembekileyo lwenkqubo ephumelelayo kunye nekhwalithi ephezulu.
